I just returned from a vacation in Italy and visiting wineries in Montalcino. We visited 13 wineries in 4 days and it was quite the experience. All the wineries except one gave us a detailed tour of the vineyards, wine fermentation area and tanks, and wine cellars. Naturally they all had tastings. The one winery that did not include a detailed tour was in the middle of their harvest.
During the tastings I asked 12 of the hosts “Should I decant your Brunello and if so for how long?” The all replied “Do NOT decant!” They were adamant. They said pour a little out to test the wine taking it to the middle of shoulder and let it set for a few hours. As an alternate some said you could pour into the glass and let it breathe for 30 to 45 minutes before drinking.
I thought that was interesting because so many people say to decant Brunello.
P.S. I plan to post a review of all the wineries as time allows.
