OK, am I freaking you out yet? First kerosene then pee? Yes, cat pee!
I know, don’t blame me, I’m not the guy who first thought of this, but you know what? It’s pretty accurate! Some wine actually contains a particular sulfur compound: p-mentha-8-thiol-3-one. It’s found primarily in the Sauvignon family of grapes: Cabernet and Blanc.
In Cabernet Sauvignon, it contributes to the blackcurrant aromas of the wines. With Sauvignon Blanc on the other hand, it contributes, well, mostly cat’s pee.
