As in most old wine producing countries there is in Italy a wealth of grape traditional varieties. Unfortunately they are often overshadowed by the “international” or even Italian grape varieties that have reach international fame (say, sangiovese or nebbiolo). In October there will be a wine fair only for these lesser known grape varieties: Autochtona 2010. (Autochtone/autochthonous signifies “of local traditional origin”.)
If you want to broaden your grape variety horizon this definitely sounds like an interesting place to go: Autochtona 2010, October 25 to 28 in Bolzano.
