Is this oak tannin or grape tannin?

Tannins are derived from the skins, stems, and seeds of the grapes used to produce the wine

Are we sure these are not chestnut or oak tannin, but actual tannin from grape plants?

I’ve used this in the past 6 Berry wine batches. I didn’t detect any oak or chestnut flavor… if that’s possible. But I just thought it was for wine. Not sure
