Washington state is considering a bill that would allow beer and wine makers to offer samples at farmers markets. A few states, including Maryland, Massachusetts, New York, Oregon, and Virginia, do allow sampling at markets. But most states, including the #1 wine-producing state, California, still prohibit it. Winemakers say they should be allowed to sample their products just as any other vendor can. Opponents of the bill argue that public wine and beer tastings set a bad example for children.
