Wingman Metrics
First Impression
A 300+ bottle cellar that reads like a greatest-hits compilation of Napa's heavy hitters and Burgundy blue-chips. This is a steakhouse playing to type—DRC, Screaming Eagle, Harlan—with the price tags to match. The list has depth, but you'll pay for the privilege.
Selection Deep Dive
The Napa collection is the star here: Opus One, Joseph Phelps Insignia, Silver Oak's Timeless—all the names your boss would recognize. Bordeaux and Burgundy get serious treatment too, with allocations most restaurants can't touch. Italian Super Tuscans round out the old-world side. What's missing? Value-driven regions like the Rhône, Spain, or South America—this list assumes you're not counting zeros. It's built for celebrating closings, anniversaries, and expense accounts.
By the Glass
Twenty-five to thirty-five glasses is a solid rotation for a steakhouse, though we don't have the specific lineup. With a sommelier on staff and this caliber of cellar, expect pours that lean premium—probably starting around $15-20 and climbing fast. The glass program likely mirrors the bottle list: safe, prestigious, and priced accordingly.
Insignia by Joseph Phelps Napa Valley 2018 — $350
Still steep at 40% markup, but it's the most reasonable pricing we found on this list—and Insignia delivers the Napa power to match a ribeye
Italian Super Tuscans section
Most diners gravitate to Napa, but the Super Tuscan lineup offers Old World structure with New World ripeness—often better with beef than Bordeaux
Timeless by Silver Oak Napa Valley 2018
170% markup on a $100 bottle is just greedy—you're paying $170 for the Silver Oak name recognition
Opus One Napa Valley 2018 + Ribeye
If you're going to drop $675 on Opus, do it right—the Bordeaux blend's cassis and cedar need the ribeye's char and fat to justify the splurge
✔️ The Bottom Line
SILO Prime has the cellar to impress and the sommelier to guide you through it, but the markup strategy is old-school steakhouse aggressive. Come here when someone else is paying, or when you want to drink wines you can't find elsewhere in San Antonio. Just don't expect any favors on the bill.
