I generally pferer Spanish Cava to Champagne, especially at lower price points. They tend to be a touch sweetier, with more fruit flavors, rather than be yeasty. For the money, Cava is often a good value. Try the 2005 Juve Y Camps Brut Cava Reserva ($15.99) or Adar de Elvi Cava Brut ($24). If you are willing to spend more, then go for a Grower's Champagne which usually have more character. Try the Chartogne-Taillet Cuvee Sainte-Anne Brut ($49.99), a blend of about 50/50 Chardonnay and Pinot Noir. It has more of a toasty, nutty and creamy taste.For chocolate truffles, try a 20-30 year old Port, and most any producer will have something good. Dow, Croft, Taylor. The Banfi Rosa Regale Brachetto is another good choice for chocolate. For a local dessert wine, try the Still River Apfel Eis Apple Ice Wine ($25), which is made in Harvard. The apple, that forbidden fruit, also makes a delightful aphrodisiac.
