Nice to see the Italians are being pragmatic. If the wine is too bad to drink then why not clean it up, dehdrate it and turn it into useful bio ethanol. Have the Italians got a sensible distribution infrastructure in place?
ReplyDeleteWow! its a very productive way of recycling waste from grapes. We can call it Zero Waste Management. The grape skins may contain less sugar but in large volume as in the vineyard, there would be enough liquid to extract and is viable enough for alcohol production.
