The Short Version
Sonoma’s heavyweights are staging technical rebellions through experimental side brands, using "alter egos" to test pet-nats and orange wines. These strategic sub-labels protect legacy reputations while offering a playground for wilder fermentations and a fresh entry point for younger drinkers.
Long-established wineries are increasingly using secondary brands to stage technical rebellions. Rather than risking a legacy label’s reputation on unproven methods, these producers launch adventurous alter egos that allow winemakers to experiment with low-alcohol profiles, orange wines, and natural fermentation. These side projects serve a dual purpose: providing a creative playground for the cellar and offering younger consumers a more approachable entry point into diverse wine styles.
The idea is to give winemakers a chance to have fun and experiment while offering consumers a variety of wine styles to explore.
Breaking Tradition Through Secondary Labels
In Healdsburg, winemaker Erik Miller has spent decades building a reputation for terroir-driven classics like Dry Creek Zinfandel and Alexander Valley Cabernet Sauvignon under his Kokomo label. However, since 2018, he has utilized his Breaking Bread brand to explore lighter, less formal expressions. The lineup moves away from heavy structures toward zinfandel-based pet-nats, whole cluster Pinot Noir, and Al Dente, a blend specifically designed to be served chilled. The idea is to give winemakers a chance to have fun and experiment while offering consumers a variety of wine styles to explore. This allows Miller to maintain his serious standing at Yountville-based Stewart Cellars while simultaneously pushing boundaries with an orange wine or a rosé.
Similarly, Blair Guthrie balances two distinct identities. While producing high-end wines for Stewart Cellars—a winery founded in 2000 by his father-in-law Michael Stewart—he operates Guthrie Family Cellars with a minimalist, organic focus. His personal brand prioritizes bright, fresh profiles through varieties like Vermentino, Grenache Blanc, and Gamay Noir, creating a sharp contrast to the more structured wines associated with his primary work.
Exploring the Natural Path
The trend toward experimentation also manifests in Lake County via Obsidian Ridge. Since launching their Cabernet Sauvignon brand in 2002, brothers Arpad and Peter Molnar have maintained a steady presence in the region. In 2020, they pivoted toward a more radical direction with The Rabbit Hole. This line leans into natural-leaning techniques that depart significantly from traditional Cabernet production.
Current releases under The Rabbit Hole include Pezsgő, a sparkling Pinot Noir pet-nat, as well as Máslás red piquette and a sweet white vermouth. By separating these wilder expressions from the core Obsidian Ridge identity, the Molnars can explore unconventional fermentations without disrupting their established market position. It is a strategic way to embrace the shifting tastes of a new generation of drinkers.
Do you prefer sticking to classic, terroir-driven varietals, or do you find yourself hunting for the experimental “side brands” on a wine list?
