On Seven is a new boutique Niagara winery owned by passionate wine aficionados Vittorio and Sula De Stefano. The De Stefanos bought an abandoned 7 acre vineyard (hence the name) in 2009 in Four Mile Creek, and under the guidance of consultant viticulturist and founding winemaker Peter Gamble, prepped the site for 3 years before replanting in 2014. The heavy clay loams are laced with calcareous deposits, and sloped north to maintain freshness. The philosophy from the beginning was to be 100% organic certified, and produce wines with minimal intervention. Wines are native fermented with no fining agents, and SO2 is added only at bottling.
