It is said that a wine is astringent when, for excessive tannins (found especially in young red wines, particularly those in Tuscany and Piedmont), there is bitterness and harshness. The effect that you feel, when you drink an astringent wine, is to feel your mouth dry and wrinkled. This can be remedied, if the bottle has not been uncorked, letting it rest longer or, if it has been uncorked, letting it aerate for an hour or more.
