The Riddler Red Wine Napa Valley. This wine has hints of wild raspberries which mingle with the taste of plums and violets and a finish of dark chocolate. It is a blend of mostly Merlot, some Cabernet Sauvignon and a bit of Malbec, Cabernet Franc, and Syrah. The flavors of the red fruits linger on the tongue. When it is opened, the nose is hit with scents of berry as well as the violets. The result is that the aroma and scent are very puzzling which is why its name of Riddler is most fitting; everything in this wine is a riddle.
