- Essential phenolics
Steven Price of ETS laboratories explored the chemistry of wine and grape structures to create the tests used in the lab. Below are a few of the compounds that make up that unique red wine feeling.
Tannin: Comes from seeds and skins, holds a stable red color and provides that astringent mouth feeling.
Catechin: Comes from seeds only, helps sort out where tannins came from .
Polymeric anthocyanins: Creates redness in tannins, marks mature grape skin.
Quercetin glycosides: One of several markers (including tannins) to test how much sun grapes get.
