1. Relentless Napa Valley, 2008
The first on our list of 10 most sold bottles of wine is the Relentless, a product of Shafer Vineyards. This excellent wine is a blend of Syrah and Petite Syrah. The winemakers use French barrels to let the wine age for 30 months, and the result is a dense, silky texture which makes the wine so famous and elite. Being an elite brand, the price is reasonably higher so a bottle of Relentless from Nappa Valley can cost around $162.
