Dan Diephouse & Jeanne Feldkamp: Oral History Interview 2025

This interview is with Dan Diephouse and Jeanne Feldkamp of Corollary Wines. We last spoke with Dan and Jeanne during the summer of 2020 after they had just released their brand, Corollary. In this interview, they briefly recap how they got into wine and started the brand, then they talk about what they have been up to since 2020.After initially releasing their wines into the world, they focused on building a wine club starting with family and friends. They also showcased their wines at Winter's Hill, which doubles as their production space, and focused on educating guests about the importance of sparkling wine in the Willamette Valley.The biggest change since our first interview was the purchase of the new vineyard site in Amity, recommended to them by Jessica Cortell. Originally a logging site, they bought it in 2022 and started prepping it for planting. They speak about the need for both a vineyard and a tasting room on the property, as well as the permaculture and sustainability initiatives they have been working towards.Looking ahead to the end of July, they speak about their work in helping to start Method Oregon, an event focusing on Willamette Valley traditional method sparkling wines. They collaborated with Andy Lytle to create the event and Jim Bernau to host the event. They stress the significance of having both an educational component as well as the more traditional grand tasting, showcasing 22 producers and helping participants to view the Willamette Valley as a premier destination for sparkling wines.This interview was conducted by Rich Schmidt at Corollary Wines in Amity on July 7, 2025.
