Ysidro Sake Spritz Returns to Thomas Keller's Addendum for Third Consecutive Season

YOUNTVILLE, CA — Ysidro, the premium sake spritz from Montecito, has officially returned for its third consecutive season at Thomas Keller's Addendum in Yountville. In a region defined by world-class viticulture, Ysidro's sustained presence in one of the most respected beverage programs in Napa Valley signals a growing appetite for high-end alternatives that prioritize quality and craftsmanship.

For emerging brands, a third season at a Michelin-caliber establishment is a different kind of milestone. It marks the transition from discovery to mainstay and confirms that the product is meeting the standards of one of the most discerning beverage programs in the country. The Addendum reorder is part of a larger pattern for Ysidro: a second consecutive season at the Hollywood Bowl, statewide retail expansion through Breakthru Beverage Group, and new placements at Bristol Farms, Lazy Acres, and 99 Ranch Market. The brand's 92% reorder rate across accounts reflects the same story: once it's on a menu or a shelf, it tends to stay there.

"Our continued presence at Addendum is a cornerstone of our brand story," said Monica Epstein, Co-Founder & CEO of Ysidro. "To be invited back for a third season in the heart of wine country is the kind of validation that speaks for itself. Napa sets the bar."

Fans of the brand can find Ysidro Sake Spritz available at Addendum throughout the 2026 season, paired perfectly with the legendary garden-side atmosphere that has made the venue a Yountville destination.

Ysidro Sake Spritz is made with super-premium Junmai Ginjo sake, organic grapefruit, and sea salt — 6.9% ABV, 250ml can, gluten-free, sulfite-free, and non-GMO. Crafted by the oldest Master Sake Brewer in the U.S. Available at Addendum throughout the 2026 season and statewide at Whole Foods, Bristol Farms, Lazy Acres, and 99 Ranch Market, and at ysidro.com.
