"The key, we think, is not only the age of his vines but the fact that they are nearly all naturally low-yielding ancient clones: Corvinone (40%), Corvina Grossa (25%) and Rondinella (20%). Corvinone, in particular, is quite rare today because of its low yields and finicky growing habits. Yet, Tommaso claims it is the Corvinone that gives his wines their depth. He calls it the 'Super Corvina,' saying that it produces stronger, denser, richer, more perfumed wines.
Small percentages of old vine Cabernet Franc, Cabernet Sauvignon, Dindarella and Pindara round out the cepage, along with new experiments like Teroldego. Tomasso makes two ranges of wines: BG is his standard tier; TB is a selection he makes in the vineyard and winery of his very best wines. Despite being Tomasso's "standard" wines, the quality of his BG selections rate near the summit of the Valpolicella pyramid. All of the production comes from estate fruit -- including declassified wine from top vineyards like Alto, Soto el Barbi, Casali, and Quarer Longhe." -Importer
