Source of Tannins Found!
Hey Everyone! Tannins are a compound vital to wine making. It’s what gives body to red wines (white wines usually don’t have tannins because they’re not fermented on their skins and/or the white grape varieties weren’t bred to have many tannins). But until now, we have had no idea where they originated in the cell. I thought this was a nice interest piece for here in Napa.
