Different wines constituted of lighter purple grapes may doubtlessly degrade quicker. Professor Sacks added that sauvignon blanc based-wines are a few of “probably the most readily oxidizable.”

Against this, probably the most tannic grapes are likely to make the sturdiest wines, akin to some cabernet sauvignons from California and Bordeaux, some brunellos from Tuscany, that are constituted of sangiovese, some Barolos from Piedmont, that are constituted of nebbiolo, and a few syrahs.
