Claire Weinkauf

Winemaker, Owner, Calistoga Lover
Meet Claire Weinkauf, a French native who grew up in Auvergne: the land of Volcanoes and fabulous cheeses. Inspired by the power of a Mouton Rothschild, she earned a wine degree in Chile and then embarked for France to work harvest in St Emilion and the Côte du Rhône. While working in South America, she met Paul Hobbs and got a job first at Viña Cobos in Mendoza, Argentina, then later in his winery in California.

In 2010, Claire started a a business development company focused on helping California wine producers including Matthiasson Wines, Long Meadow Ranch, Morlet Family Estate. 

Picayune Cellars was founded in 2011 with Claire' good friend Jennifer Roberts. They both shared the same love for drinking quality wines and the same drive for searching great value. Surrounded by a pool of amazing winemaker friends, Claire and Jennifer decided to follow the classic French Negociant model as a California winery and buy small lots from the hands of our talented friends and give them a new future.


Since 2017, Claire focuses solely on Picayune Cellars. She lives in Calistoga with her husband, Aron Weinkauf of Spottswoode Winery, and their two children.

“The wine was excellent, the cheese and charcuterie were delicious, and Jayne-Marie was a very friendly and knowledgeable host. Add to that a unique selection of souvenirs for sale, and it was a wonderfully memorable experience all around. They are also conveniently located in the midst of Calistoga with easy parking.“
