The CC carmenere and the California Cab Sav are stellar after a year, and better at 1.5 years, as is the Rosso fortissimo. The Rosso has a funk though the wife isn't a fan of, I believe it's a heavy cassis which I enjoy, it's unlike any other wine I've tried. All three kits were made without an additional. The CC amarone and Walla Walla Washington cab Merlot are tasting fantastic so far tweaked only with cellaring tannins, they won't hit their one year anniversary until May though so they still need time. So far I think the California Cab Sav is my favorite but all are excellent. I have not made any others, although I'm curious to try the Washington Merlot and the Malbac. What's your favorite?
