One way to chase away the chill of a cold December evening is to open a bottle of a big, brash zinfandel from California. Powerful and intensely fruity, these red wines often taste of concentrated berries, black pepper and spices. Old vine zins, made from vines that are typically more than 50 years old, are particularly known for their intensity and flavor. These robust wines are a great choice for hearty, winter foods, but be aware that some are high in alcohol.
