My wife and I both have problems with gluten so we’ve been brewing our own GF beer for the last ~7 years. It was difficult to get started but the output is well worth the effort!
Most of them are darker brews (stouts, tripels, etc). This is one of our lighter holiday ales that came in ~8% ABV.
Welcome to Mander!
Ginger-Millet beer sounds amazing. I haven’t yet tried a lot of non-malt brews for beer. I personally love hops so we always add a few from our little planter outside for flavor. Originally we were trying to make GF clones of regular gluten beer, but as we progressed it became easier to work up unique combinations.
The holiday ale that’s pictured above is much heavier on spice than malt flavor. When combined with the naturally lighter gluten-free malts like sorghum you don’t get that heavy malt hit. It may be close to what you’re looking for. I’m traveling on vacation right now but can pull some recipes from my log book when I get back.
On a slightly different note, have you ever tried making mead? It’s the classic honey, spice, and herb beverage.
edit: I forgot to add that my standard brew is much heavier. Stouts and tripels are my go-to. I’ll pull up some of those recipes too.
