Vernaccia di San Gimignano, potentially distinctive dry white wine made from the historic local vine variety of the same name, probably unrelated to any other Vernaccia, cultivated in the sandstone-based soils around the famous towers of San Gimignano in the province of Siena in tuscany in central Italy. There are references to Vernaccia in the archives of San Gimignano as early as 1276. The wine was the first ever awarded doc status, in 1966, and was elevated to docg status in 1993 in recognition of its unquestioned superiority over the standard bland Tuscan white blend of Trebbiano Toscano and Malvasia.
