Companion was born out of the idea that delicious, terroir-driven, natural wine from California could be sold at a cost and in packaging that is accessible to all. This is an endeavor that celebrates Riesling, sunny days, the beach, the park, granite boulders, spicy food, and good friends. 

Ryan Stirm began his winemaking career first through a love of farming. His passion was for the land and what could be grown but eventually turned towards vineyards specifically, wine became his way of documenting a place and time. While most of his winemaking pedigree has been etched in California, he spent time in the Wachau in Austria (Weingut Tegernseerhof) and also in Margaret River, Australia. Abroad he was able to hone his craft making Riesling and Grüner Veltliner as well as learning about the best practices in vineyard management. Ryan currently splits his time between the cellar and the vineyards he is contracted to tend in the Santa Cruz Mountains. Companion is his platform for showing the vast potential of Riesling and California viticulture.
