Wine tannin v grape tannin?

[zonkman]

I have a (banana wine) recipe that calls for grape tannin. My local supply store only had "wine tannin" (LD Carlson). It prescribes the same dosage per gallon.

Are the two the same - or near enough - that wine tannin can be used instead of grape tannin?

Probably. The LD Carlson tannin is probably derived from trees (probably chestnut, maybe oak). I suspect it will be a bit harsher than what the recipe calls for, but will likely do the trick!
