Owner and winemaker Byron Kosuge spent the first fifteen years of his winemaking career in Saintsbury in Carneros. His time there established him as a Pinot Noir and Chardonnay specialist. After leaving Saintsbury in 2001, Byron assumed winemaking duties for several small projects, including Miura Vineyards – where he still consults – McIntyre Vineyard and Aiena Wines.
His own label, B. Kosuge Wines focuses on Pinot Noir, Chardonnay and Gamay from several different sites in the Sonoma Cast and Carneros. These are elegant, artisanal wines that showcase California terroir in a classic, yet unique way.
