The story behind the name


When friends and winemakers Micah Joseph Wirth and Adrian Jewell Manspeaker teamed up in 2006, they made their first wine together in a Windsor garage. With two French oak barrels, a small basket press, and exactly one ton of Russian River Valley grapes, they produced 50 cases of single-vineyard Pinot Noir. With no winery affiliation or property of their own, they combined their middle names for the new venture and pooled their resources to build their own wine company dedicated to capturing the unique terroir of single-vineyard sites. The success of that first release enabled Micah and Adrian to invest seriously in their project and grow their garage experiment to a 2500-case production of exceptional wines.

Micah_mediumMicah is the fourth generation in a family of wine pioneers. Raised in Alexander Valley, his interest in wine started at only eight years old when he accompanied his winemaker father Chris Wirth to work at Preston Vineyards. Once he was old enough to be helpful in the cellar, Micah learned the basics of winemaking from his father at ElvenGlade and Raptor Ridge in Oregon. The logical next step was enology classes at UC Davis, and then grueling 15-hour days of harvest internships at Chalk Hill Winery.


A year later, he was hired on full-time at Gary Farrell Winery. For the next 7 years, he worked with highly regarded winemakers Gary Farrell and Susan Reed. The hard work fueled Micah’s passion for winemaking and his ambition to start his own label. His tenure as Cellar Master at Gary Farrell was instrumental in developing partnerships with grape growers and securing top-quality fruit for Joseph Jewell.



JJW-411_mediumHaving grown up on the fog-shrouded northern coast of California, Adrian learned early on to appreciate its complicated patchwork of micro-climates. When he moved to Sonoma County, his upbringing sparked an interest in the origin of wine and the evolution from vineyard to barrel to bottle.


His wine country location allowed him to conveniently study winemaking and viticulture at UC Davis’s extension program and take business management courses on the side. He put theory into practice at C. Donatiello for the 2007 crush, and lent a hand at Peay Vineyards during the 2008 harvest.


Around that time, he teamed up with Micah and the two became business partners. Adrian’s intense drive and commitment are apparent in every detail of his work, from his relationships with the growers to the design of the labels to the overall quality of the finished product.
