Live Like the World is Dying: Sean on Brewing

Margaret: Hello, and welcome to Live Like the World is Dying, your podcast for what feels like the end times. This week we're talking about fermentation. We're talking about little things that eat things and then poop out alcohol. I actually don't really know because I'm the one who's going to be asking these questions and I record these introductions before I actually do the interview. So, I'm going to be learning more about fermentation and we're gonna be talking about alcohol, but we're also gonna be talking about all kinds of other stuff too. And I think you'll get a lot out of it. And first, we're a proud member of the Channel Zero Network of anarchists podcasts and here's a jingle from another show on the network. La la la, la la la la [Margaret making musical melody sounds]

Margaret: Okay, we're back. And so if you could introduce yourself with your name, your pronouns, and then I guess like a little bit about how you got into fermentation?

Sean: So my name is Sean. Pronouns are he/him. Well, I actually started with, with cider and mead because I had a harder time finding commercially available cider and mead that wasn't just kind of like a novelty product or obscenely expensive, you know, imported from like Basque country or whatever. So that's, that was kind of where I got my, my kickoff on fermentation. I worked in commercial fermentation doing sour beer production as well as like conventional clean, you know, canned beer, and then actually worked in sales and distribution with beer for a while.

Margaret:Okay, so this is really exciting because I've always kind of wanted to get into this. Well, I've kind of wanted to get into everything, which is the whole reason I started this podcast, so I could ask people about how to do things. But fermentation...so you can format things and it makes them different? What is fermentation?

Sean: So fermentation basically is either yeast or bacteria breaking down almost always some form of sugar or carbohydrate. The main thing that is being produced by that is co2. But a nice little side effect that is often produced is alcohol, right, or lactic acid is often produced especially in the presence of bacteria, specifically in the presence of lactic acid producing bacteria. We call them you know, LAB is the abbreviation that's used. So, fermentation is happening generally-when people are referring to it--they're referring to yeast fermentation. So the most common yeast, Saccharomyces cerevisiae, right, beer yeast. It's the same. It's called beer yeast. But that's the same yeast that's used to ferment wine. It's used to ferment like a sour mash, if you're, you know, making whiskey in a legal distillation situation as opposed to you know, the other distillation situation. It is illegal to distill alcohol for home use in the US. So, yeah, you have to be very careful you don't do that. On Accident.

Margaret:Yeah, we won't cover that for a while.

Sean: Yeah, right.

Margaret: Okay, wait, is this the same yeast as like sourdough and all of that?

Sean: It's very, very close. So sourdough is--especially if you make like a if you'd like a sourdough starter capture right from the air... I have not done this. It's something I've wanted to do. I've captured wild yeast for brewing from the air but never for baking. But they are a similar blend of airborne yeast, so you'll have wild yeast. You'll have wild Saccharomyces cerevisiae as well as wild other yeasts, Brettanomyces. Yeast strains are very common in air. And then you'll also have lactic acid bacteria in the air. So these are those rod shaped bacteria that are active in the absence of oxygen. They're anaerobic bacteria. So, they will continue to acidify things, even when there is no oxygen present to like kind of fuel or catalyze that reaction in a way that regular beer yeast, or even bread yeast, baking yeast, right, won't necessarily be able to do.

Margaret: I'm really not used to the idea of thinking about bacteria as a positive thing.

Sean: Right. No. So they are extremely a positive thing, Lactic acid bacteria, because they drop the pH as well. And lower pH means you don't have to worry about like botulism, for example. You know, so that's definitely a benefit. Most spoilage...So one number I'm going to be saying probably a few times is 4.2. 4.2 is like the pH level, below which you have a greater degree of protection because of the acidity, right.

Margaret: Okay. Cause botulism doesn't like hanging out in there?

Sean: Botulism is...I'm not 100% sure if it's the pH, the alcohol, or both. But botulism does not like low pH, nor does it like high ABV. So these are, these are both good ways of protecting yourself from that.

Margaret: So it's that kind of...so fermentation probably comes originally, basically...Well, probably by accident. But originally probably comes from people just basically desperately trying to figure out how to make sure food doesn't go bad. And this is and fermentation is like, one of the many ways that humans have developed to keep food from going bad? Is that a?

Sean: My theory is that's why fermentation stuck around. I think it showed up eventually because human... ancient, you know, human beings, proto humans even, you know, proto hominids realized they could get fucked up with it.

Margaret:Yeah. That's fair.

Sean: I think that's the key point. Like human nature hasn't changed that much. That will always be the driving influence on novelty, I think.

Margaret: So, what are some of the things--I'm going to ask you about some of the specifics about how to do this a little bit--but what are some of the things that you can ferment? I know, you can make sauerkraut and you can make pickles? Nope, that's not fermentation.

Sean: No, lacto fermented pickles, absolutely. That's frementation.

Margaret: Oh, yeah. No, I totally knew that. That's definitely why I said it.

Sean: Not like quick pickling with vinegar in the fridge. That's not an active fermentation process. And I do that too, like quick pickled red onions are like...those go well on everything. But no, like actual, like long term pickling. Hot sauces are a big one. You know, I did a batch of...I grew a bunch of jalapeno peppers. And then
