The Name. We were working (and getting way inspired) in South Africa for a vintage when we decided to make our own wine. But what to call it? “Birdhorse” emerged after a few beers while reflecting on a certain NPR news quiz - and it stuck, representing both our personalities and our winemaking philosophy. Adventurous and fun, yet believers in great science and winemaking fundamentals.

The Wine. Birdhorse represents our hope that there is still room to innovate winemaking in California: that new perspectives can succeed; that 80%+ of the market does not have to be dominated by just ~7 grapes from a handful of regions; and that sincere wine lovers are looking for challenging and interesting gustatory experiences. Our toolkit includes intellectual curiosity, transparency, science, and data, but most importantly a passion for delicious libations and sharing them with the wider drinking public.

We’re excited to have you join us for an enological adventure of epic proportions.

Our Team

Corinne Rich


Corinne was born and raised in Sonoma County, California, to parents that had zero ties to the wine industry other than being passionate consumers. She went on to earn her B.A. in Chemistry at the University of Pennsylvania and, after the world’s briefest stint in pharmaceutical research, she returned to her native northern California and dove head-first into wine production. She spent time working the harvest circuit across a variety of regions, including Sonoma, Willamette Valley, New Zealand, and Australia before returning to school for her M.S. in Viticulture & Enology from UC Davis. There she met Katie Rouse and, well, the rest is history! The two worked a harvest in South Africa, got a wallop of inspiration, and returned home to start Birdhorse. When she’s not elbows-deep in a Birdhorse ferment, Corinne has a day job as a Cellar Master at a beloved St. Helena winery.


Katie Rouse


Katie did her undergrad at Whitman College, where her rampant enthusiasm for all things rock-related earned her a B.A. in Geology. Born of the grapes into a winemaking family in Rockbridge County, Virginia, Katie naturally gravitated back to winemaking while living in Sonoma, California where she was working in the Carneros. Whilst nerding out and earning her M.S. in Viticulture & Enology from UC Davis, she joined up with Corinne, and is now thrilled to have found a partner in, well...everything! Katie just wrapped up a harvest exploring the wines of the Côte de Beaune at Domaine Dubreuil-Fontaine in Burgundy, France.


Tyler Ernst

Tyler earned a B.S. in Chemical Engineering, a B.S. in Economics from the Wharton School, and a Master of Biotechnology while at the University of Pennsylvania. Most importantly from Penn, though, came a now-decade-long friendship with Corinne (which featured an odd amount of Lady Gaga and flavored vodka — tastes have improved, we promise). He worked for five years in management consulting and private equity, and is pursuing his MBA at the Stanford Graduate School of Business. His background in wine is limited to enthusiastic consumption, so he tries to stay out of the way while Corinne and Katie do the important stuff.
