If you’re skeptical about the One Pot Brewing system, you should be. Here are some questions and answers (or lack thereof), based mostly on experience and some knowledge.
You must make shitty beer, right?
That’s not an option for me. I love beer. If my beer didn’t taste really good, I wouldn’t brew. My goal is not only cheap and easy beer, but good beer. I hold my beers to the same standard as you do: commercial craft beer. Many times I prefer my IPA over theirs (of course I’m a little biased). I do not have a super refined, certified judge palate; but I know good beer when I taste it.
Q: You ferment in a 7.5 gallon pot, with only 5.5 gallons of beer in it. Isn’t that a problem? Won’t that “oxidize” your beer?
Don’t think so. Here’s another problem: having to clean and sanitize yet another vessel, or cleaning up a huge mess when your fermenter has popped the top (be honest: it’s happened to you or someone you know). Or worrying about whether you need to hook up a blow tube or not. I don’t know the science, but I have heard that a layer of CO2 protects my beer against oxidation, which makes some sense to me. Secondly, I have heard that if the vessel is taller than it is wide, it’s all good. What really matters to me is taste: I don’t taste oxidation off-flavors in my beers (so far…that’s over 60 batches).
Q: You bottle directly from a spigot attached to your pot. And you don’t use a bottling wand!
Yes, that’s true. I never have. And yes, some oxygen gets in while bottling. However, I drink my beer within a month or two. I believe that oxidation takes a little while to present itself (I could be wrong about that). Third, if you transfer your beer into different vessels (secondary, bottling bucket), you also have oxidation issues bro. But honestly I’m not super happy with my current spigot. I would prefer a spigot with a smaller opening, so that it could attach to a bottling wand. I simply cannot find one, anywhere. Let me know if you can.
You tie up your only brewing vessel vessel for weeks?
Yes, about 1.5 to 2 weeks while it ferments. How much do you brew? More than that? Holy shit: are you selling it? Are you a raging alcoholic? Are you doing all your brewing at once? Procrastinator!
Your beer tastes like Aluminum, right?
No. I was worried about this from the start, and I was worried for a second about my first batch, but it turns out that aluminum is a fine vessel for fermenting beer in. However, apparently you have to “break it in” so to speak, by boiling water in it first, which creates a protective layer between the aluminum and the beer. I don’t know the science that well, only that it works. Now, of course you could do One Pot Brewing with stainless steel. The pots are just more expensive and heavier. I like cheap and light.
