Don't miss the chocolate and wine pairing at Keuka Lake Vineyards!! My personal favorites for 2012 are the Cabernet Franc and the Kashmir Spice chocolate. The vineyard setting is gorgeous and the wines are delicious. The staff is friendly and knowledgeable but after several visits this summer, I have noticed that they do tend to rush you through your tasting if there are a lot of people there. Make sure you enjoy the tasting at a pace that is comfortable for you.
A quick note - if you like the chocolates (Chocolate Moderne), make your purchase at the winery. It's cheaper there than you will find anywhere else.
