Memento Mori is a new winemaking venture started by three partners, all with backgrounds in high technology or finance. The partners are Hayes Drumwright, Adriel Lares and Adam Craun. Their winemaker is Sam Kaplan, one of Napa Valley’s rising winemaking stars. Memento Mori sources grapes from top Napa Valley vineyards, including Beckstoffer’s Dr. Crane and las Piedras Vineyards, and Weitz and Oakville Ranch Vineyards in Oakville. The estate makes a premium Cabernet Sauvignon at the rate of about 600 cases per year. It is generally available only through its mailing list, and it has impressed reviewers. Robert M. Parker Jr. awarded the 2013 vintage 97 pts and called it “brilliant.”
