About Confluence Estate Vineyard & Winery Limited

A firm believer in growing the right variety for the terroir. All work is done by hand including hand harvest. Cover crops are used to encourage beneficial insects and optimize the organic matter in relatively poor soils. Our goal is to grow grapes which require minimal winemaker intervention in the winery to produce premium wines.
