I'm reviving my old thread to give a little update on progress.
Just last night I opened the result of one of these "test batches." But first I'll back up to the beginning.
I started off buying 4 1-gallon glass carboys from Uline. I then called my LHBS and ordered the smallest grain bill ever - 3.25 pounds. I buy a lot from them, so they were willing to make 10-ounce and 2-ounce bags of some of my grains. I then made a 3L starter from my White Labs yeast, and separated the yeast into three mason jars. I used one of these to pitch my 1-gallon wort, which I brewed BIAB-style and fermented in a 2-gallon bucket.
After about 10-14 days, I transfered the beer into a 1-gallon carboy and let it sit for another week or two. Then I took another carboy, added my priming sugar, and simply transfered from the secondary into a clean carboy. That's right - I have a 1-gallon "bottle" of beer. I primed direclty in my growler!
I truly expected failure (and of course, wasn't worried about throwing out about $10 bucks worth of beer if that was the case). But when I unscrewed the cap to a surprising "WOOSH" of releasing pressure, and then poured one of the most beautiful beers I've ever seen, complete with persistent head and gorgeous lacing, I was frankly amazed.
And the taste? Let's just say having experienced my first beer judging competition this past Saturday, I'm thinking I have a potential BOS on my hands...
This process will be repeated. If anyone has any questions, feel free to ask.
