Nebbiolo - Soil Nutrients and Grape Tannins

A colleague sent me this as an explanation for the difference in styles of Barbaresco and Barolo - “The soil in Barbaresco is richer in nutrients and, because of this, the vines don’t produce as much tannin as found in the wines of Barolo.” This info may come from Wine Folly. Is there any truth to this statement? The only thing I could think of was that a grapevine with more vigor would produce larger berries.

Hi T.J., you might try posting this in Wine Talk. I don’t know of anyone ITB on the production side in Piedmont who frequents this board, but there are some extremely knowledgeable enthusiasts of Piedmont wines who would see it there.

Thank you, Doug. I will do that.
