Recently opened Napa Costco might just feature the best wine selection in the entire United States, according to the San Francisco Chronicle. The new store, which opened on October 18, has already garnered attention for its impressive wine section, thanks largely to one exceptional employee—Selman Medina. A well-known figure in the Bay Area Costco community, Medina has spent 11 years commuting from Napa to work in the wine department at Novato Costco, which has long been regarded as the best wine section among all Costcos in California.
Medina is one of only 30 “wine stewards” employed by Costco across the country and is also a co-founder of two prominent wine stewardship programs. When he learned that a Costco would be opening in his hometown after 35 years, he immediately requested a transfer. His extensive knowledge, charm, and friendliness make him a significant draw for members who might otherwise shop in Novato.
In many ways, Medina’s role resembles that of a sommelier. He engages with customers to recommend wines he believes they will enjoy, seamlessly connecting with Costco’s daily clientele—after all, he is a Costco customer himself. “What I love about wine is its connectivity,” he explains. “Wine is a benefit, a reward.”
For many of his customers, Medina has become a trusted wine expert—not just at Costco, but beyond. “He’s a local celebrity. He could have his own YouTube channel,” says David Wise, a long-time customer from Novato. “He always tells the truth, and he buys all his own wine.”
One notable recommendation from Medina is a wine called “Son of a Butcher,” crafted by French winemaker Yannick Rousseau in Napa. This Tannat-based blend is often overlooked on the shelves, but Medina’s enthusiasm for it struck a chord with customers, leading to a rapid sellout of an entire pallet within three days.
We asked Medina to recommend three fantastic wines available at the new Napa Costco, and here’s what he suggested:
1. **Louis M. Martini Monte Rosso Gnarly Vine Zinfandel, Sonoma Valley, $58.99 (typically retails for $100)**: Medina says, “This vineyard is exceptional for producing Zinfandel.”
2. **Baker & Hamilton Vine Hill Ranch Cabernet Sauvignon, Oakville, $65.99 (usually priced between $125 and $150)**: Coming from one of Napa’s most esteemed vineyards, Medina believes this is one of the best deals in the Napa Costco wine section.
3. **Viñedos del Contino, Contino Blanco, Rioja, $39.99 (rare to find elsewhere)**: While discussing this Viura and Grenache Blanc blend, Medina notes, “It’s a very unique blend, barrel-fermented with a long finish.”
With selections like these, it’s clear why many consider Napa Costco’s wine section to be a standout in the region.
