Sinegal Estate

Napa Valley, United States

Philosophy

Field-first micro-farming and fermenting approach with unrelenting attention to detail. State-of-the-art equipment ensures only the finest fruit enters barrels; 100% off-grid operations reflect commitment to treading lightly on the earth while honoring the terroir inherited from 1881 plantings.

Reputation

Sinegal Estate inherits a storied property on the western edge of St. Helena's benchland, where the first vines were planted in 1881 by Alton Williams. The historic Inglewood estate, purchased by Costco co-founder James Sinegal and his son David in 2013, has been meticulously restored to honor both its 19th-century heritage and modern sustainable farming practice.
