David Coffaro himself tends to every aspect of the wine-making process at his namesake winery, where memorabilia of his beloved Oakland Raiders lines the wall behind the bar. (On game days, you might find staffers watching the action on a large screen tucked between the barrels.) Despite the relaxed attitude, Coffaro is serious about wines. He specializes in reasonably priced single-varietal wines—Zinfandel and Petite Sirah are strong suits. He also makes wines using Lagrein, Aglianico, and other less familiar grapes, which also find their way into his unique blends.
