I actually have the gear to 'brew' the higher octane stuff ;-)
I got started back in the 90s when I did a research paper on it.
Funny thing was my old scoutmaster had been brewing for years and taught me a lot. My favorite were the laugers, however, you have to ferment at 55* and I had to get a fridge to do it. Awesome stuff with a good kick.
Tasted like sweet tea with a little carbonation to it. Alcohol content was 8%
