No, I haven't been getting up to bizarre hijinks with Caribbean beverages. I just made three different types of ginger beer while testing for Vegan in the Sun.
The first one I tried was unfermented. It was basically just ginger and boiling water, sweetened with homemade simple syrup. I didn't add much syrup, so it's pretty much like drinking straight up ginger. Here it is, sitting and steaming:
Making these drinks was a bit of a project (depending on the kind, they took two days to nearly a week to be ready), but worth it, since I'd never had ginger beer that wasn't like a soda before. And I'd never fermented anything before. And I very rarely make drinks (aside from tea). The only other beverage I can think of that I've made is Terry's horchata from Viva Vegan! (which I also recommend). I guess recipe testing inspires me to make things that seem more complicated than I would normally bother doing for myself.
