AMASS Brands Group (NASDAQ: AMSS) shares dipped Friday, as the company, a premium, multi-category beverage platform spanning non-alcohol, functional, and alcohol 2.0 products, today announced the expansion of Summer Water Rosé into 37 Costco locations across California, building on the brand's national presence at leading retailers, including Whole Foods, Total Wine, FreshDirect, Foxtrot, H-E-B, Central Market, and more.
In addition, Wine Enthusiast has awarded Summer Water's 2025 vintage 92 points and a Best Buy designation, marking the brand's sixth consecutive vintage rated 90 points or higher. New Nielsen data also confirms Summer Water as the best-selling domestic rosé in the $15–20 price tier nationally.
The streak includes a 93-point Editors' Choice distinction for the 2024 vintage, an honor earned by fewer than 1% of the rosés reviewed by Wine Enthusiast and tied for the publication's highest-rated rosé priced between $15 and $20 worldwide.
No conventional still rosé has ever earned more than 95 points from Wine Enthusiast, underscoring the consistency and quality Summer Water has maintained across vintages.
"In the wine business, consistency is what earns consumer trust, and consumer trust is what earns long-term retail partnerships," said CEO Mark Thomas Lynn.
According to Nielsen data for the 52 weeks ended July 11, 2026, Summer Water holds a 17.3% share of the domestic rosé category priced between $15 and $20, the largest share of any domestic brand in the category.
Summer Water also outsells the next-largest domestic rosé at that price point by more than 20%. Including imports, Summer Water ranks sixth among all 613 rosés sold nationally in the $15–20 range, and 17th among all 2,144 rosé brands tracked across every origin and price tier in the U.S.
AMSS lost five cents, or 3.8%, to $1.19.
