Treveri Cellars is a family-owned sparkling wine house that produces some of the finest handcrafted sparkling wines in the United States.

Treveri opened its doors on November 23, 2010 with a mission to put Washington sparkling wine on the map. Since its opening, Treveri wine has been served at White House State Department receptions and the James Beard Foundation in New York.

Producing a wide array of sparkling wines, including non-traditional varieties such as Riesling and Mueller-Thurgau, Treveri largely focuses on 100% varietal sparkling wines, and is also launching a reserve tier of sparkling wine.


“Part of the fun of wine and winemaking is the journey you take.
It never really ends, but continues to develop as the years go by.”
-Jürgen Grieb, Head Winemaker and Owner
Juergen Grieb
Head Winemaker & Owner

Juergen Grieb was born and raised in Trier, Germany, where he received his formal winemaking and sparkling winemaking degrees. While in school, Juergen learned to produce some of the finest Rieslings in the Mosel-Saar-Ruwer at Karthäuserhof Winery. Juergen studied under the tutelage of Herr Breiling and Christoph Tyrell, two of Germany’s most decorated winemakers. With an expertise in Riesling, Juergen also developed his passion for sparkling wine. He pursued a second apprenticeship at the Duhr Sektkellerei in downtown Trier. There, he learned the craft of Méthode Champenoise sparkling wine production.

Wilson Cecil
National Sales & Brand Manager

Wilson’s fascination with wine started in the summer of 2007, but his career in the industry officially began in 2011. After two years spent at loose ends post-college, Wilson settled in Boulder, CO and snagged the only job in wine and spirits he could find: cashiering at a liquor mega-retailer. A month later he had found his way into the store’s wine department and learned all that he could about wine, spirits, and beer from his co-workers. He spent four years in Boulder, moving on to manage a boutique wine shop, and attaining his Certified Sommelier with the Court of Master Sommeliers. In 2015, he followed his then-girlfriend, now-wife, to Yakima, WA in pursuit of her medical education. After a stint working harvest he found his way to Treveri Cellars.

When he is not working, or exploring Philly, you can find Wilson at home: cooking, boning up on his wine knowledge, playing music, or reading a good book.
