The Short Version
As heavy reds lose their luster, veteran winemaker Carol Shelton is pivoting to whites and rosés to burn through a massive 17,000-case Zinfandel surplus. It’s a high-stakes survival play against plummeting tasting attendance and skyrocketing overhead costs.
Carol Shelton isn’t closing her doors just yet. Despite recent headlines suggesting an immediate shutdown, the veteran winemaker plans to continue operations for at least another two years. She is currently navigating an industry downturn defined by sluggish sales and a consumer shift away from the big, burly reds she helped popularize.
I began calculating what I call a ‘burn rate’ — how long it will take to sell through a particular wine.
Managing inventory and changing tastes
The shift in demand has hit Shelton’s production hard, particularly her Wild Thing old vine Zinfandel, which accounts for roughly 70% of her output. As consumers trade heavy reds for lighter profiles, even dedicated groups are struggling; Shelton notes that Zinfandel Advocates & Producers is on its “last gasp,” with annual tasting attendance plummeting from 9,000 people to perhaps 200. I began calculating what I call a ‘burn rate’ — how long it will take to sell through a particular wine. This calculation is critical, as Shelton holds more than 17,000 cases of Zinfandel alone, alongside Cabernet Sauvignon, Barbera, and Petite Sirah. To adapt, she has pivoted her energy toward producing rosé and white wines, including Chardonnay and her Rhône-inspired Coquille Blanc.
Rising tariffs have inflated the cost of essential supplies, from Portuguese corks to Chinese glass. Even the wooden pallets used for delivery have jumped from $5 or $6 at her launch in 2000 to $18 today. These overhead spikes arrive just as foot traffic at her Santa Rosa tasting room has dwindled; weekend guest counts have dropped from nearly 20 per day to as few as seven or eight.
Real estate hurdles in Windsor
While managing current stock, Shelton and her husband, Mitch, also face complications with a 4.8-acre property they purchased in Windsor in 2018. Originally intended for a custom-crush facility and restaurant, the project’s projected costs ballooned from $19 million to over $30 million due to pandemic delays and permit negotiations. A recent moratorium on self-storage facilities in Windsor effectively halved the land’s value after a potential buyer fell through.
Shelton notes that local officials have suggested businesses that generate higher sales tax revenue, but the light industrial zoning makes such developments difficult without significant capital. For now, the priority remains selling through their substantial inventory. Once the winery eventually closes, Shelton intends to transition into traveling, consulting, and painting.
How can specialized producers survive when consumer trends shift so aggressively away from traditional varietals?
