The Effects Of High Blood Sugar Levels

Tannic acid is a particular type of hydrolyzable (basically means that it is able to be split up and broken down by interacting with water) tannin commonly found in the bark and wood of oaks and other plants. It is used commercially in tanning leather and in certain dying processes. So, what type of tannin comes from the bark of oaks and other plants? Hydrolyzable Tannins.

When distinguishing tannins from acidity, it is easier to start by comparing a white wine that has not been aged in oak (perhaps a Riesling-it is usually quite high in acidity) with a deep red wine (perhaps a Cabernet Sauvignon from California or Australia).

When you try the white wine, you’ll notice the tart, zingy flavor that makes your tongue salivate a little. Kind of like drinking orange juice.
