I'm obsessed with BSA's raspberry sour, a non alcoholic beer that tastes like sour raspberries with a hint of beer or grain or something. I want to make something similar.
It doesn't have to be exact. I don't need it to taste like beer at all, I just want a fizzy sour raspberry drink with a hint of... unpleasantness? to make it a beverage you'd sip slowly, like wine or coffee instead of guzzle like a raspberry italian soda. I'm thinking something like kombucha or water kefir?
I'm also ok with a higher alcohol content than NA beer, although not by much - I'm not avoiding it for medical or sobriety reasons, it just makes me feel gross. I don't plan to drink a ton of this stuff though, I usually have one, rarely two of those beers in one night.
