I like sour beers, so I wanted to try making one, but I wanted to avoid infecting my equipment. I’ve been told that the bacteria you use in a sour beer can get into your plastic and rubber fittings and it’s nearly impossible to get it out.

One way to avoid that problem is to sour some wort first, then boil it to kill the bacteria.

Some people use grain to sour the wort. To do this you just make a small batch of wort, drop some grain in and allow the bacteria that lives on the husks to get to work. I’ve been told that method works, but I hear it’s a pretty smelly process.

A while ago I decided to try my hand at kombucha. You can read a little about that on this page.

Kombucha is fine. I don’t like sweet drinks, like soda, and I try to stay away from too much caffeine, so a batch of decaf kombucha can be nice after work. But I’d rather drink a beer, so I decided to experiment with souring some wort with my kombucha mother and using that in a Belgian-style sour.

Here’s how I did it. These procedures are designed for a 3-gallon batch. I did 3 gallons because I do kombucha in a one gallon jug, and 1 gallon of soured malt in a 3-gallon batch seems to be about the right ratio. Your mileage may vary.

To start you have to have a batch of regular kombucha, which means you’ll need a scoby. You can buy one or you can grow one. Here’s a good page about kombucha.

Assuming you’ve got all that straight, here’s how you make Kombucha Sour Ale.

On the day you’re ready to bottle your kombucha, boil 1.5 cups of amber DME in 13 cups of water and let it cool. When it’s cool, reserve 2 cups of your kombucha and bottle the rest. Inspect your scoby to make sure there’s no black spots, rinse it off and set it on a clean plate.

Rinse out your kombucha jar, add the reserved two cups of kombucha, add the 13 cups of malt you boiled and cooled, then add the scoby. Cover it with a cloth and let it sit for 2 weeks.

On brew day, prepare whatever you’re going to put on your scoby next — whether that’s tea or more malt. Remove the (now soured) malt from the kombucha jar and reserve two cups. You’ll use those for your next batch of kombucha.

Pour all the rest of your soured malt into your kettle then proceed as if you’re doing a very simple extract recipe.

4 pounds amber DME
1 oz. Saaz (60 min.)
1/2 oz. Saaz (30 min)
1/2 oz. Saaz (10 min)
Irish moss (10 min.)

Boil for an hour, cool, add water (if necessary) to get to 3 gallons and pitch Belle Saison Ale Yeast. Ferment and bottle or keg like any other beer. (Since you boiled your soured wort, there’s no risk of infection in your kegging equipment. Also, if you choose to bottle remember to adjust your priming sugar for a 3-gallon batch!)

I’ve tinkered with this recipe a few times — sometimes using a little more DME, sometimes leaving it on the scoby a little longer. But each batch has been very good.

Even if you keg your beer, from time to time you’re going to want to bottle some of it. There are a few things you want to look for when selecting your bottles.

Use brown bottles — Light can damage your beer, so don’t use green or clear bottles. Stick with brown.

Don’t use twist-offs — Your caps won’t fit properly. Stick with pry-off tops.

Use returnables, if you can get them — I imagine this varies from state to state, but if you can get returnable bottles, use them. They’re thicker and stronger than regular bottles.

Stick with bottles of the same general size and shape — It helps when you’re stacking cases. Also, note the distance between the lip of the bottle and that little indentation about a half inch down. (I’ve marked in on the photo to the right.)

Stick with bottles that have about the same distance there. On some bottles that distance is really short and the caps don’t go on quite as well.

Use glass — Modern plastics are pretty good, so you shouldn’t get off flavors from good quality plastic bottles, but I know some pretty smart people who say you should avoid eating food out of plastic whenever possible.

The exception here is if you have trouble with your carbonation. If you think your beer might be overcarbonated, by all means use plastic. Bottle bombs with glass are not a joking matter.

Note how well labels come off — Different brands of beer use different methods of securing the label to the bottle. Some of them come off easily after soaking the bottle in water, while some you need a sand blaster to remove.

I don’t particularly care if my homebrew has some old label on it, but … it’s still nice to have a clear bottle.

Avoid bottles with labels around the neck — Some bottles have a label at the top. This gets in your way when you’re filling, because you can’t see how much beer you’ve put in the bottle.

If somebody hands you a Pale Ale, you have certain expectations about what you’re getting. If it’s the color of a porter, you’re going to have that “this isn’t what I ordered” feeling.

Likewise, if you’re in a bar where they have English Ales on tap, you have a reasonable expectation that the ESB is stronger than the special, which is stronger than the bitter.

Well and good. That’s the right use of styles. Words should mean things.

Some folk seem to take this proper need for defining a style a little too far. In my opinion, there’s usually not a sharp line between one style and the next. There’s some overlap where, for example, a porter could be very like a stout, or it’s a matter of a coin toss whether an ale is a brown ale or a mild.

That is, styles have fuzzy edges — a fact that is recognized in the BJCP style guidelines.

Many styles are quite broad and can encompass multiple stylistically accurate variants.

A few times I’ve run into people who are a little too particular about style definitions. It’s as if they feel the need to show off their beer knowledge and be persnickety about minor things. I find it tiresome.

I like beers to be faithful to their styles (or to come up with a new style, if that’s necessary), but I don’t like to be too precise about it.

Distillation is illegal, because the stinking revenuers want their tax money. But is there a way for crafty people to make their own whiskey without running afoul of the law? Read on, my friend.

All liquors come out of the distillation process clear and most liquors get their color and flavor from the aging process. That got me thinking. If I can’t distill the alcohol (because Governor Tarkin says I can’t), I can still age it. That’s perfectly legal.

Inventive, imaginative, innovative people like homebrewers should be able to get around this. So here’s my idea, and my challenge to other homebrewers.

The idea is to create new and interesting kinds of liquor by focusing on the aging part of the equation. That is, buy some grain alcohol, dillute it as necessary, and mix it with various things to create a new flavor of liquor. (Or age it and then dillute it. I’m not sure yet which is the right approach.)

I’ve tried it, and my first batch turned out pretty well.

The People’s Republic of Maryland recently outlawed the sale of grain alcohol, but it’s still possible to buy very strong neutral spirits. I bought some Everclear that was 151 proof, which worked just fine for my purposes.

For some reason I had the mistaken notion that bourbon is supposed to be aged in charred oak barrels that had been used to age burgundy. That’s not so. Bourbon has to be aged in new charred oak barrels. But proceeding according to my misperception, here’s what I did.

I bought some oak chips from Maryland Homebrew and soaked them in red wine for a week. (I used Merlot because that’s what I had.) Then I took the oak chips out to my mini charcoal grill and smoked / charred them on a small wood fire. Then I mixed my 151 Everclear with enough water to get it close to 80 proof and soaked that on my charred wood chips for a couple weeks.

(I’m not giving you precise figures because I want you to experiment, and I’m not confident my recipe is the best place to start.)

What I ended up with was a very smoky amber-colored drink that could pass for scotch or bourbon. In fact, I think it’s quite good. I’m having a small glass right now.

I need to play with the recipe a bit. I think it’s a touch too smoky, and I want to try it again with oak chips that were simply charred and not soaked in wine. But this idea creates a whole new area of exploration and experimentation for me.

Here’s the best thing about it, in my opinion.

When real distilleries age whiskey or bourbon, they store it in oak barrels and rely on a very slow process by which the alcohol soaks into and out of the barrel because of changes in atmospheric pressure and whatnot. It’s a painfully slow process that can take years.

Since I’m soaking the alcohol in wood chips, it all happens a lot faster. No, it’s not precisely the same as the process that “real” whiskeys go through, but … I’m not trying to duplicate Maker’s Mark. I’m trying to invent my own thing, and I’m too old to wait three years for each batch.

My method — from start to finish — takes a few weeks. And it will take even less time when I skip the soaking in wine part. I think that’s pretty darned cool.

The air temperature in your kegerator or lagering fridge doesn’t always track with the temperature of your beer, so a thermostat that’s measuring air temperature isn’t controlling the right thing. To get a consistent temperature you need to measure the temperature of the liquid.

I tend to be more of a “relax, don’t worry” kind of a brewer. My process makes very good beer, and that’s good enough for me. But that means that one batch of my California Common is not always the same as the next batch. They’re both good, but they’re not consistent. I’m okay with that — at least for now — but if I wanted to fix it, one of the main ways to get more consistency with your beer is to control your temperature better, especially during fermentation.

Recently I heard about the Sure Temp Thermometer and I was curious about it. I asked Chris at Maryland Homebrew about this and she said “we have been telling customers to do just this with empty white labs vials. They drill a hole in the lid and stick their thermostat controller into it.”

There’s the DIY solution if you love to tinker, or if you want to buy one pre-made, go here, or read more about it on this page — Sure Temp Thermometer Measures Product Temperature.

If you want to learn more about the importance of temperature control, here’s a good page. Fermentation Temperature Control. It says “Fermentation temperature control is the single most important thing you can do that will make the most dramatic improvements in your beer.”

Okay, maybe. Don’t people say that about sanitation?
