Oh man! You need to check out Herbal Academy's Fermentation course online! It's a short course with videos and printables you can order that walk you through how to do all sorts of fermentation - kombucha, beer, mead, keifer, etc. And the beer is all herbal, so there are no grains! Perfectly gluten/wheat free! I wrote a post on a lavender lemon balm beer I made this summer: http://hillsborough-homesteading.com/lavender-lemon-balm-beer-recipe/ It was ridiculously good!
