White Silo in Sherman specializes in fruit wines: rhubarb, blackberry, raspberry, and black currant. The idea that fruit-based wines are always sweet is a misconception, said winemaker Eric Gorman, who added that the farm is just beginning to grow white Cayuga and red Frontenac grapes for wine making. Dry Rhubarb ($12) wine and the house Sangria, made with Dry Rhubarb and Sweet Blackberry, are the biggest sellers.
