About Stryker Sonoma Winery
Stryker Sonoma Winery sits at 5110 Highway 128 in Geyserville, in the heart of the Alexander Valley AVA, where the winery has been producing estate wines since 1999. The Alexander Valley is Sonoma's warmest and most generous AVA — a place where Cabernet Sauvignon reaches a ripeness and softness rarely found elsewhere in the county, and where Zinfandel and Merlot also thrive in the well-drained benchland and valley-floor soils.
Stryker's program is built around comprehensive Alexander Valley exploration — the winery produces an unusually broad range of varietals from the appellation, including Cabernet Sauvignon, Merlot, Zinfandel, Chardonnay, and several Rhône-inspired blends. This breadth reflects a philosophy of showing visitors the full range of what Alexander Valley can do, rather than betting everything on a single flagship variety. The estate vineyards are farmed sustainably, with an emphasis on low yields and concentrated fruit.
The tasting room is open daily from 10:30am to 5pm with walk-ins welcome — one of the more laid-back and accessible tasting experiences in Geyserville. At $20 to start, it's also among the better value propositions in northern Sonoma County. The winemaking team has maintained consistency across vintages while continuing to refine the estate Cabernet program, which represents the winery's most serious and cellar-worthy expression.
"Stryker is a reminder that Alexander Valley's best wines don't need famous names or famous price tags — just good farming and honest winemaking."
For visitors making their way up Highway 128 through the Alexander Valley, Stryker offers a genuine and unhurried tasting experience with serious wines across a thoughtfully broad range of varietals. The proximity to Geyserville makes it an easy pairing with the area's other notable producers along this stretch of wine country.
