Annulus Cellars is a family wine venture founded in 2019 by Luke Evnin and Deann Wright, longtime Rutherford residents, alongside their daughters Alexandra and Elena. Winemaker Nigel Kinsman — who also crafts Accendo and Bella Oaks — and consulting oenologist Michel Rolland craft vineyard-designate Cabernet Sauvignon from two of Napa Valley's most prized sites, Beckstoffer Las Piedras and the historic Vine Hill Ranch, planted in 1884. The name is Latin for "ring," inspired by a sculpture the family saw in Florence and the cyclical rhythm of the vineyard year.
