Merriam Vineyards

Peter and Diana Merriam purchased the Windacre Vineyard in 2000, one of the oldest vineyard sites in Sonoma County. The couple chose this winery in part because of the land’s unique qualities, ideal for growing Bordeaux-style varietals, and the micro-climate’s similarity to the Bordeaux region of France. From the start, Merriam Vineyards has been committed to sustainable farming practices and environmental stewardship, which means minimal intervention to the natural growing process while allowing vines to thrive.


Merriam Vineyards wines are inspired by traditional French styles of farming and winemaking. Our commitment to delivering vineyard-designated wines allows us the opportunity to create unique wines that will live up to their old-world inspiration. Much of this dedication is evident in the fields and on the vines, where a commitment to sustainable farming practices and environmental stewardship thrives. Our award-winning wines, inspired by Bordeaux and Burgundy styles, serve as a testament to our inspiration and ideals as grower and winemaker.

Wine Making

Winemaking: In the less-is-better tradition of winemaking, Merriam Vineyard wines are crafted with minimal intervention. Winemaker Jonathan Bomberg and his team take extreme care with every step of the process; grapes are picked, sorted of debris, and placed in small batch fermentation tanks by hand. After fermentation, the wine goes into medium-toast, one hundred percent French oak barrels, where it is racked throughout the year on what is known as a Bordeaux schedule; three or four times in the first year and twice the following year, which eliminates the need to filter our red wines.
