Woodson is an oenophile who developed his interest in wine while playing football for the first time in Oakland, near the Napa Valley. He partnered with former Robert Mondavi winemaker Rick Ruiz to develop a signature wine label, "Twentyfour by Charles Woodson". The company is based in Napa, California, and is a small boutique winery, producing fewer than one thousand cases per year of its two varieties, Cabernet Sauvignon and Cabernet Franc. Although the wine bears his name and signature, Woodson was warned by the NFL not to be seen endorsing the wine himself because of the league's alcohol policy.
