Gary Ardnt:

Hello everyone.

2

:

And welcome to another episode

of respecting the beer.

3

:

My name is Gary Ardnt with me.

4

:

Again, is Bobby Fleschman

brewer extraordinaire.

5

:

And once again, Joel Hermanson, and we

are here to talk once again about history.

6

:

Everything we've talked about so

far with respect to the history of

7

:

the beer, you could almost say that

early beer and beer making was all

8

:

homebrewing to a certain extent.

9

:

Even if like it was a monastery that

was producing large quantities of it, we

10

:

would still kind of consider it having

been done in a method very similar to

11

:

homebrewing, which is very different

than the way beer is produced today.

12

:

It's done at industrial.

13

:

So.

14

:

In this episode, we want to

talk about the origins of the

15

:

industrial production of beer.

16

:

And where would you say that that began?

17

:

Where was the transition point from

this beer being widespread, but locally

18

:

produced and produced kind of on a,

you know consume it as you make it

19

:

kind of basis to what we see today?

20

:

Joel Hermansen: I think a, a wonderful

stat to share with you on this is the fact

21

:

that, that, that last 30, 40 years of the

19th century, there's more change that

22

:

happens in that time period to beer that

maybe happens in all of the time preceding

23

:

those, those brief decades, going

back all the way to the ancient world,

24

:

there are remarkable changes in beer.

25

:

You talked about the transition, and

just to frame this contextually, this

26

:

is in that period after the 30 Years

War, in which the brewing industry takes

27

:

a long time to recover as a result of

the calamity that was, and it returns

28

:

more to that cottage industry phase.

29

:

I think when Europe goes, or when,

particularly when England goes through

30

:

its agricultural revolution in the

early:

31

:

something called scientific farming.

32

:

And the process of, of farming

had changed dramatically.

33

:

They're using a three field

system, they're using fertilizers.

34

:

So their grain yields are,

are growing exponentially.

35

:

And subsequently they have

more, excess grain to work with.

36

:

They also have a population that

was lowered thanks to the, to the

37

:

30 years war and the subsequent

plagues that, that affected it.

38

:

So you can't really just jump

in and say, Oh, well, it was

39

:

the, it was the malting roaster.

40

:

And it was the, the processes that

were changed with, you know, malting

41

:

and drying and things like that.

42

:

You can't, you can't jump into that.

43

:

I don't think without talking

about the agricultural side.

44

:

So I would say that as, as kind of

my initial foray into the question,

45

:

The other thing that I would point out,

and I'm going to lean more on Bobby

46

:

to talk a little bit about this style

of beer cause this is something that

47

:

we haven't focused that much on, but

when beer had been malted and dried

48

:

before I would say before the beginning

of the 19th century, it always had

49

:

a smoky quality about it, which is

actually its own style, that Rauch beer.

50

:

And there's going to be

some substantial changes.

51

:

to the technology that

gets rid of the smoke.

52

:

Do you want to talk a little

bit about that style of beer?

53

:

Bobby Fleshman: Yeah, I think I mentioned

a little bit on another podcast about

54

:

the Rauk beer that's, that you'll

still find today in Bamberg, Germany.

55

:

that's sort of the home of and

the vestibule, or what's the word

56

:

I'm looking, vestige of the style.

57

:

And yeah, there was a time when all beer

would eventually be sour over time, and

58

:

there was a time when all beer was smoky

because you directly heat the grain

59

:

in the process of kilning and malting,

and that heat source is wood burning,

60

:

and the smoke's making its way into the

acid from the, from the smoke, making

61

:

its way into the husk of the grain.

62

:

And it's just part of the it's

just part of the flavor profile.

63

:

No one would have consumed it

and said this is smoky or not.

64

:

That's just part of that baseline profile.

65

:

We recognize it today, obviously,

but back then they wouldn't have.

66

:

So, yeah, you're this, this, this change,

though, with the advent of coke, coke is

67

:

a derivative of coal and it's, it's used

as a clean source of heat and doesn't

68

:

produce these, these smoky flavors.

69

:

But also this is an industrial age.

70

:

But also they've found ways

to indirectly heat their mash.

71

:

So there's a barrier, physical

barrier between the two, the

72

:

heat source in the, in the mall.

73

:

So, yeah, that lead

weight, all kinds of stuff.

74

:

And then also the smoke gives

you darker colors and you're

75

:

able to make lighter kiln malts.

76

:

And then the Pilsner malt is

invented and the rest is literally

77

:

history because the number one beer

in the world is a Pilsner today.

78

:

Still today, but there's a, there's a

several light beers coming, popping up

79

:

in Europe as soon as you can make those.

80

:

And I think previously we

talked about glassware.

81

:

how that grew up alongside having

clear beer or lighter colored beers.

82

:

And it would be a, a signature of

prestige to have a glass with that liquid.

83

:

Joel Hermansen: Because before that

you would use pewter because you

84

:

didn't really want to see your beard.

85

:

It's all black.

86

:

Because it was, you know,

things floating in it.

87

:

Gary Ardnt: Let me ask you

a hypothetical question.

88

:

I podcast once about language,

and a lot of linguists say that

89

:

we could talk to Queen Elizabeth I

better than she could talk to her

90

:

grandmother, that there was a period.

91

:

In the 16th century where the

English language changed so much

92

:

that it just became unrecognizable.

93

:

If you were to take somebody from say

the 16th century and bring them today and

94

:

serve them a beer, do you think that they

would recognize it or, or vice versa?

95

:

If you were to travel back in

time, how different would their

96

:

beer be to a modern palette?

97

:

Bobby Fleshman: That's a great, the

only way I can answer that is the, is by

98

:

giving you my own account of having tried.

99

:

And I'm not throwing anyone under

the bus now because I think that

100

:

styles are always, there's no, from

on high, there was no list of beer

101

:

styles that existed before earth.

102

:

We had to make it, these styles.

103

:

I've had a slushy in the last year.

104

:

Slushy is a beer that is 30 percent fruit

and it's got all these different flavors.

105

:

Vanilla sometimes shows up in it.

106

:

And I had it and I could not myself

recognize that as being a beer.

107

:

I'm not saying it's that extreme,

but I might, I would imagine they

108

:

would have some sort of reaction

that, that, that's related to that.

109

:

Hopefully it wouldn't be as extreme

as mine was to it, but who knows?

110

:

Cause these are wildly different flavors.

111

:

Joel Hermansen: I think your, your

cask beers would, would be closer,

112

:

Bobby Fleshman: closer, but

again, without the smoke.

113

:

And, if we talk a little bit.

114

:

About porters in a moment, I

kind of recapping what I've said

115

:

previously that the porter is based

on sort of three different beers.

116

:

It's sort of a stream of milds

and brown ales and stouts and

117

:

different sourness levels.

118

:

So they were, they were finding ways to

deal with that sourness at some point.

119

:

But yeah, everything had

a certain palette to it.

120

:

I think the sugar sweetness actually

was much higher in these beers.

121

:

Hoppiness was much higher

to balance that sweetness.

122

:

I don't know, Gary.

123

:

That's a good question.

124

:

Joel Hermansen: I don't

think they would like 547.

125

:

Bobby Fleshman: Well, they did actually

hop beers as much as that, but,

126

:

but they were also extremely sweet.

127

:

So they just, they seemed

much more in balance that way.

128

:

Not to say five 47 isn't in balance

with our intentions, but yeah,

129

:

there is a drift in our palates.

130

:

Gary Ardnt: And we we've

mentioned it several times.

131

:

Five 47 is a double IPA that you make.

132

:

It's one of your signature beers, I think,

133

:

Bobby Fleshman: and has its own bell.

134

:

Gary Ardnt: And Joel is a very big fan

of it, which is why we've mentioned it.

135

:

Bobby Fleshman: It's a big ambassador.

136

:

Gary Ardnt: Has anyone ever tried to make.

137

:

Like these historical beers?

138

:

Bobby Fleshman: Yeah, I would think

dogfish head probably of all the

139

:

the commercial breweries out there

that do it Nash Nationally, they

140

:

they probably have tried the more

than most to do that, you know

141

:

Joel Hermansen: I I don't I'm sure there's

European brewers that probably dabble in

142

:

that more than then they would stateside.

143

:

Bobby Fleshman: Because you also

get, you have to get a yeast

144

:

that's not super awesome at

making beer by modern standards.

145

:

It's the one that can't actually

finish all the, consume all

146

:

the sugars that are there.

147

:

And so they built recipes around that.

148

:

That's why they use so many hops.

149

:

You wouldn't have noticed it, for example.

150

:

Joel Hermansen: And for those listening

you can tune into episode two where

151

:

Bobby's wife, Alison, will talk about the

fact that really brewers don't make Beer.

152

:

Yeast does.

153

:

Yeast is, yeast is the driving

force behind this entire.

154

:

Bobby Fleshman: We just run the resort.

155

:

Joel Hermansen: Right.

156

:

Make them comfortable and

they're going to do the rest.

157

:

Yeah.

158

:

They're going to do the rest for you.

159

:

Flush them down the drain.

160

:

Bobby Fleshman: But while they're

here, they're going to get the best.

161

:

Gary Ardnt: You talked about.

162

:

Coke, which allowed for higher, you know,

coke is usually used in steel making.

163

:

Bobby Fleshman: Right.

164

:

Gary Ardnt: It allows

for higher temperatures.

165

:

And it also, as things get more

industrialized, probably allows

166

:

for more consistent temperatures.

167

:

True.

168

:

You know, you'd have a recipe

that was like, you know, boil us

169

:

for, you know, I don't know if

you've ever seen actual recipes.

170

:

There's a YouTube channel called Townsend

where this guy makes 18th century recipes

171

:

and the recipes are always very vague.

172

:

It's like, yes, take a duck and throw

some salt on it and cook vigorously.

173

:

And that's all they say.

174

:

So as we're moving towards this

modern era, we're developing things

175

:

that are like Coke that probably

allow for more consistent heating.

176

:

What are some of the other big

technical innovations that radically

177

:

change brewing in that period?

178

:

Cause you're talking about

that late 19th century,

179

:

Joel Hermansen: Enormous changes, the

rotating roaster is, is another one.

180

:

Bobby Fleshman: Oh yeah.

181

:

You're looking into Germany.

182

:

Yeah.

183

:

I'm sorry, England.

184

:

You get the, the roaster allows you to

make what's called black malt or, and

185

:

they, it actually is called even today

it's called black patent malt because

186

:

that was a patent on that machine.

187

:

So we still call it that.

188

:

Joel Hermansen: Now, all of a sudden you

have the ability to manipulate color.

189

:

Yeah.

190

:

Which otherwise you have.

191

:

Gary Ardnt: What is this,

what does this device do?

192

:

Bobby Fleshman: It's a tumbling

roasting machine that it's not

193

:

that much different than a coffee.

194

:

One, I think 50 percent of the time

you would have though in these times

195

:

a fire breakout, so they didn't have.

196

:

They didn't have any control

because we're talking about 450

197

:

degrees and up in temperature.

198

:

So you're, you're always just on the

edge of igniting the whole damn roaster.

199

:

So only in the very modern times

that we've been able to control that.

200

:

And so no one dared make those

malts intentionally until

201

:

we had that under control.

202

:

Joel Hermansen: Yeah.

203

:

So that with respect to the

transformation of beers color.

204

:

and different profiles of it.

205

:

I think we'd be naive if we didn't

mention railroads which certainly

206

:

brought beers from one place to

another at a much quicker pace,

207

:

probably extended the dominion of beer.

208

:

I think that, that is certainly one,

an instrument that I know you use a

209

:

lot was developed in the 19th century.

210

:

If you could give us just a super

fast overview to the hydrometer.

211

:

Bobby Fleshman: Well, and thermometer.

212

:

They're both because of brewing.

213

:

But, but yeah, the hydrometer is a floaty

device and you can calibrate it so that it

214

:

floats higher if it, if the liquid it's in

is denser and you can put markings on it.

215

:

And once they were able to independently

determine the density of that, of

216

:

that liquid, and they could calibrate

their, these floating devices, it's

217

:

important to measure the amount of sugar.

218

:

That's going into the word,

which becomes the beer.

219

:

And out of that, they can predict the

level of alcohol and the government

220

:

loves it because the government can

step in and say, Oh, when it hits

221

:

this mark, nevermind what beer you're

making, they're going to charge you this

222

:

much for that beer so that they were

basing their taxation on the amount of

223

:

sugar and not the amount of alcohol.

224

:

And there've been others that.

225

:

Modern.

226

:

We in modern context, we actually do

measure the alcohol, but back in the

227

:

day, that was the way it was done.

228

:

I think in Scotland you have shilling

beers and various numbers, and that

229

:

was based on the strength of that work.

230

:

Joel Hermansen: So in other words,

standardization again, where you

231

:

can come back and be reliable Yes,

to the production of, of one style,

232

:

Bobby Fleshman: Two countries

are responsible for industrial

233

:

brewing more than any others.

234

:

Belgium really stuck with its roots.

235

:

It's very much based with monasteries

and some of the sour beer brewers of with

236

:

intent and the saison brewers in France.

237

:

But then you look at the Germany, as

we talked about in the last episode

238

:

with Ryan Heitzke about standardization

and then England as well, they

239

:

became such a global superpower.

240

:

They, they just industrialization changed.

241

:

everything there and they're able to

make, they were ahead of Germany for a

242

:

while in terms of, production volume,

but also in terms of technology, they

243

:

were taking it everywhere in the world.

244

:

They had such a huge

market for their beer.

245

:

Gary Ardnt: What about bottling?

246

:

Joel Hermansen: Before we get to bottling,

we'd also be remiss to, to ignore

247

:

the, the technology of steam power.

248

:

Which can, you know, all of the

machines that are, that are, you

249

:

know, powering these, these breweries

that are starting to appear in

250

:

Europe, putting steam in them as a,

251

:

Gary Ardnt: No, obviously if you're

going to have a gigantic brewery, it's

252

:

going to be machine based and it's

going to require a source of power.

253

:

But the reason I bring up bottles is

because even if you had this industrial

254

:

facility, If it's just creating kegs of

beer and it ships it out, there's going

255

:

to be a limit, I think, in terms of

freshness that as far as how far you can

256

:

transport it and how long it can stay.

257

:

What did bottling do?

258

:

Because once you bottle something,

you're sealing it, which is kind of

259

:

different from the way beer had been

served You know, up until that point,

260

:

Bobby Fleshman: Right.

261

:

I would say though, at the end of

the day, the, the bottle and the cask

262

:

are going to, to some extent, age.

263

:

Similarly, the, the bottle though

allows for, more individual purchasing.

264

:

So I can only, I can only speak

to what I would imagine would

265

:

have been a distribution that

you wouldn't have seen before the

266

:

creation of the single serve packet.

267

:

Joel Hermansen: Yeah.

268

:

And I think World War I accelerated

the use of, of bottled beer because

269

:

when you're supplying that much

beer to the men in the front lines.

270

:

Bobby Fleshman: Steel cans as well, right?

271

:

They had steel cans.

272

:

I'm not sure what they were lined

with, but yeah, it's probably nothing.

273

:

Yeah.

274

:

So that's frightening.

275

:

Joel Hermansen: Yeah.

276

:

And you know, that, that time period after

World War I is you approach, you know, the

277

:

Volstead Act here in the United States,

but in the depression as well, that's

278

:

when people start to drink more at home.

279

:

And, you know, prior to that, if you

were drinking, you were going out.

280

:

to drink, as opposed to,

you know, drinking at home.

281

:

Well, we're, we're

particularly here in Wisconsin.

282

:

We're used to, you know, to doing both.

283

:

Yeah.

284

:

That, that wasn't really an option before.

285

:

Bobby Fleshman: Fast forward hundreds

of years, just a quick comment.

286

:

Since the pandemic, we've seen

people shift, hard into cans

287

:

that take it home and it's, it's

shifted our, our, our approach.

288

:

Gary Ardnt: Oh, with regards

to what the cans were aligned

289

:

with, I believe there were 10.

290

:

so a tin can is not a can made of tin.

291

:

It's okay.

292

:

It's a can that's lined with tin.

293

:

Got it.

294

:

And, I know this because I did an episode

on food canning and the first canning

295

:

of like beans and stuff like that.

296

:

I believe it was the lining with tin

that allowed it to kind of happen.

297

:

Got it.

298

:

So I'm guessing that probably

did the same thing with beer.

299

:

Bobby Fleshman: I assume.

300

:

Gary Ardnt: Yeah.

301

:

Joel Hermansen: So the

greatest technology though.

302

:

of this time period is not the

heat structure for malting, it's

303

:

not the rotating drum roaster, the

train, the steam power, bottling.

304

:

It is the isolation of yeast

and the science behind yeast.

305

:

Bobby Fleshman: Microbiology.

306

:

Yeah.

307

:

Joel Hermansen: Louis Pasteur, they,

they change every, I mean, people

308

:

forget he actually worked in a brewery.

309

:

Yeah.

310

:

Bobby Fleshman: The, the thing that

I, I, maybe I've mentioned this

311

:

previous episodes, but biochemistry

was born, microbiology were born

312

:

from, from the field of brewing.

313

:

There's a lot of, we just glazed over

a lot of engineering accomplishments

314

:

that the Germans were able to

give the world from, from brewing.

315

:

But I was going to say in

the Louis Pasteur Context.

316

:

Louis Pasteur was able to show that

you can take a yeast cell, kill

317

:

it, split it open, and then you can

put sugar into what remains of it.

318

:

And then that sugar will change.

319

:

it'll go from starch to sugars.

320

:

It'll break down the chains.

321

:

And so what he was able to

demonstrate at that moment is

322

:

you don't need something alive.

323

:

to cause biological processes to occur.

324

:

So what he understood at that

point, and, and I maybe even

325

:

named, was the amylase enzymes.

326

:

He was able to identify their enzymes

inside of yeast, they don't require

327

:

the yeast to be alive, and out of

that was born biochemistry, and out

328

:

of that was born everything that

we appreciate in modern medicine.

329

:

Joel Hermansen: Gotta

come back to that quote.

330

:

From Charlie Bamforth, beer is the

basis of modern static civilization.

331

:

It seems that all of these, these

things are being generated from beer.

332

:

I mean, we started with

agriculture and now we're at,

333

:

we're, you know, at microbiology.

334

:

It seems that there are so

many intersections for this.

335

:

Bobby Fleshman: So that's, this

is a long winded answer of why

336

:

would I choose this career, right?

337

:

Everyone's like, why'd you choose it?

338

:

It's just beer.

339

:

No, it's clearly not just beer.

340

:

There's a lot here.

341

:

It will never end.

342

:

Gary Ardnt: As we go

through the 20th century.

343

:

And I should say we are recording this

in Wisconsin, and I would say for most

344

:

of the 20th century, this was the center

of beer making in the United States.

345

:

Many of the biggest brands,

Schlitz, Pabst, Miller, Blatts,

346

:

whatever they were all located here.

347

:

And as these beers became

bigger many communities.

348

:

At least in Wisconsin, I'm

guessing in many other places,

349

:

had a local brewery where we are.

350

:

There was an Adelaide

Brewery just a block away.

351

:

Other communities had them

and they all kind of died out.

352

:

I would say 1960s, 1970s, and we wound

up in this place where we had only

353

:

large industrial beer, you know, makers

and strangely enough, that almost was

354

:

the seeds of it's, you know, every

revolution as the seeds of its own demise.

355

:

Was that kind of then the start of

craft beer making and craft breweries?

356

:

You think, I mean, you can see the

cycle where it gets industrialized

357

:

and it gets so industrialized

that it kind of loses something.

358

:

Bobby Fleshman: Well, the T

Tolar movement, it's definitely

359

:

where this story begins.

360

:

And, and I think that even the

women's right to vote, I think there

361

:

was, there's a whole long story.

362

:

Gary Ardnt: The suffrage movement

and the temperance movement are

363

:

highly intertwined in a way that

I think has been forgotten today.

364

:

Bobby Fleshman: Talk

about a butterfly effect.

365

:

We've just opened up 17

different podcasts, but yeah,

366

:

Gary Ardnt: I, and to be fair, America

had a huge drinking problem in the

367

:

late 18th and early 19th century.

368

:

Bobby Fleshman: It was opportunism though,

for, for people to take advantage of that.

369

:

But yeah, I think to answer, just answer

your, your question on it's on its face.

370

:

Yeah.

371

:

I think that the, the craft beer

movement definitely came about because

372

:

of industrialized and, and monopolized

nature of the beer industry, for sure.

373

:

Yeah.

374

:

Gary Ardnt: I collected beer

cans as a kid in the:

375

:

and there weren't a whole lot.

376

:

There were some regional

breweries you'd find cans for.

377

:

But it's not like it is today.

378

:

You know, Appleton had its brewery.

379

:

Oshkosh had its brewery.

380

:

Now there's how many different

places that brew beer in just this

381

:

city, which is not a huge city.

382

:

Bobby Fleshman: Right.

383

:

It's when, when we, when we were

moving here, planning this, there

384

:

was one brewery and I think now there

are some small ones, but I think

385

:

there's seven now just in our town.

386

:

Yeah, that gives you some.

387

:

Gary Ardnt: But in some ways I

suppose you can think of this as a

388

:

continuation of that same process.

389

:

That the industrialized the

industrialization has made the

390

:

tools and the technology so

available and abundant, right?

391

:

That's something like this is possible.

392

:

Bobby Fleshman: The problem

now is the economics.

393

:

That's the only thing.

394

:

Now, the barrier for the small breweries,

there's a volume you have to hit for

395

:

it to make sense and and that's where

we are in the craft beer industry.

396

:

And that's that's for a

whole other episode for sure.

397

:

Gary Ardnt: Before we close this up,

what are your, your kind of your thoughts

398

:

on the process of industrialization?

399

:

Do you think it was, I

mean, obviously it was good.

400

:

It allowed, you know, beer to

become more standardized, but

401

:

what do you think was lost?

402

:

If anything, because there's

always a, a trade off, right?

403

:

Bobby Fleshman: Yeah, I think, right.

404

:

I think we've definitely lost.

405

:

I think even today we're, we've

discovered what are called kveik

406

:

yeast from Norway, Sweden, some, I

forget which countries they originate.

407

:

These are yeasts that are made, used to

make loggers quote at high temperatures.

408

:

And these yeast were lost to the,

they were lost forever until they

409

:

were discovered in the last 20 years.

410

:

So I think we're now we're,

we're actually playing catch up.

411

:

Trying to connect back with those,

some of the styles that existed,

412

:

I think is a treasure trove.

413

:

I don't think they're gone forever.

414

:

It's not like we're reaching back

10, 000 years trying to discover.

415

:

yeah, I think we, we probably

did lose something there.

416

:

What did we gain?

417

:

Well, we have a stable supply chain

and we have ingredients available to

418

:

us because of the biggest brewers and

tech now technologies that are used

419

:

within and outside of the beer industry.

420

:

Gary Ardnt: In the island of Falsbard

up in Northern Norway, they have a seed

421

:

bank where they're keeping copies of

like all the various seeds for plants.

422

:

Is there anything similar for yeast?

423

:

Maybe not a doomsday fall, but

like, you know, someplace that's

424

:

trying to categorize and create

a library of these yeasts.

425

:

Bobby Fleshman: So it's easy today,

quote, easy today to cryo store yeast

426

:

for perpetually for their forever.

427

:

I would say in the last, well, 60 years.

428

:

That's been the case.

429

:

I'm just throwing a number out there, just

having a very little knowledge about it.

430

:

But I know that any brewer who's of any

scale keeps their beer on ice, so to

431

:

speak, even if they're not using it,

even if they haven't used it in 60 years.

432

:

Budweiser probably has, but

Their own series of yeast.

433

:

They've gone through

over their, their time.

434

:

That's still cataloged away.

435

:

Yeah.

436

:

I don't know if there's like one global

one because there's a lot of proprietary

437

:

nature behind this, but the big boys,

definitely the medium boys to little guys,

438

:

maybe not so much collecting wild yeast in

your backyard as a whole whole new thing.

439

:

And it was done

inadvertently all over time.

440

:

It's uncountable number of yeast.

441

:

Joel Hermansen: There's probably

incredible biodiversity in

442

:

the yeast species, too, that

443

:

Bobby Fleshman: I'll read up on

the origin of lager yeast, and we

444

:

should talk about that at some point.

445

:

Because that's a remarkable story.

446

:

I need to make sure I

get all my notes right.

447

:

Because I'm not a microbiologist,

but I'll do my best to tell that one.

448

:

Joel Hermansen: He could

be by your next episode.

449

:

Bobby Fleshman: Well, let's bring one on.

450

:

I'll find one.

451

:

Gary Ardnt: All right.

452

:

We are going to be talking more about

the history of beer in the future.

453

:

There's a lot more to be said and

there's a lot more deep dives we can

454

:

do on some of the topics we touched

about, but I think that does it now.

455

:

Joel, do you have any last

thoughts about beer history?

456

:

Joel Hermansen: Well, I do.

457

:

I, I, I would be remissed cause

we kind of glossed over it.

458

:

early as something that was

going to change beer, but

459

:

then we never came back to it.

460

:

But we should just give a quick shout

out to refrigeration, which was a

461

:

late 19th century phenomenon that

that, that revolutionized brewing

462

:

almost as much as yeast probably did.

463

:

Bobby Fleshman: Yeah.

464

:

Ultimately it's what led to Anheuser Busch

being the largest brewer in the world.

465

:

Now they're, they're AB and Bev and,

and, but yeah, for sure they, and

466

:

they had the rail, they had access.

467

:

To the rails and

refrigeration on the trains.

468

:

There's so many things that are happening.

469

:

Yeah, for sure.

470

:

Refrigeration is And then the rest

of the world benefits as well, right?

471

:

I think

472

:

Joel Hermansen: my takeaway from

our discussion today is just

473

:

there's so many intersections

between these, these technologies.

474

:

And, you know, we've come back

to it that that beer is the basis

475

:

of modern static civilization.

476

:

It's just a great way to look at, I

think the history of beer that it seems

477

:

to beer is almost like a grain that when

you soak it, it sprouts, it seems to

478

:

sprout all these things, whether it's

writing or government or technology,

479

:

it's, it's, it's an exciting thing.

480

:

And I'm just glad you were

able to have me on today.

481

:

Gary Ardnt: All right.
