i'm not so sure it would be a very pronounced difference in the end product, but black bean paste and gochujang are both delicious.
i'd be happy with a tasty liquid version of either.
i imagine it would precipitate out too quickly. a little oat milk in the glass after you pour one might be interesting, though. or disgusting, who knows until you try.
i always do a single pint trial first just to see if i'm way off base. it doesn't even need to be the beer in question, just add progressive additions to any pint of beer, to see how much it takes to taste the difference. then scale up to total volume.
