Most guides to Sonoma wine varieties read the same way: an alphabetical list of every grape anyone has ever planted in the county, from Chardonnay down to Zinfandel, treated as if they all matter equally. They don’t.
Six varieties account for nearly 94% of everything crushed in Sonoma and Marin counties’ pricing district (CDFA District 3) in 2025. Everything else — more than 60 other varieties, some represented by a fraction of a ton — makes up the remaining 6%.
This isn’t a complete catalog. It’s the six grapes that actually define what Sonoma tastes like, ranked by what growers here actually grow, sourced to the county’s own crush data instead of guesswork.
Chardonnay
Chardonnay is Sonoma’s largest crush by a wide margin — 44,579 tons in 2025, or roughly 38% of everything crushed in the district. It’s grown nearly everywhere in the county, but it reaches its best expression in the cooler pockets: Russian River Valley and the Sonoma Coast, where fog and marine air slow ripening enough to preserve acidity.
Sonoma Chardonnay ranges wider in style than most people expect — from lean, mineral, barely-oaked wines to the fuller, richer style the variety is sometimes stereotyped for. If you’re tasting your way through it, ask which direction a winery leans before you pour; the label alone won’t tell you.
Where to find it: Russian River Valley is the heart of it — Dutton Estate Winery in Sebastopol is a straightforward place to taste the cooler style — though the Sonoma Coast and Carneros both produce excellent versions too.
Pinot Noir
Pinot Noir is Sonoma’s second-largest crush at 22,425 tons — about 19% of the district — and its highest-value major grape, commanding an average of $3,844 per ton in 2025, well above Chardonnay or Cabernet Sauvignon.
Sonoma’s Pinot Noir story is really a story about specific, small AVAs: Russian River Valley, Green Valley, and the Sonoma Coast each produce distinctly different Pinot, shaped by exactly how much fog and cold air reaches a given hillside. We’ve covered this variety in depth elsewhere — if Pinot Noir is what brought you to Sonoma, our full Pinot Noir guide goes much deeper than this article can.
Where to find it: Russian River Valley, Green Valley, Sonoma Coast — see the full Pinot Noir guide for a region-by-region breakdown.
Cabernet Sauvignon
Cabernet Sauvignon is Sonoma’s third-largest crush at 19,703 tons, about 17% of the district, and the grape most associated with Alexander Valley specifically. The valley’s warm days and cool, marine-influenced nights give the wine structure without the heaviness that Cabernet can pick up in hotter inland regions.
It’s worth remembering Sonoma Cabernet is often overshadowed by Napa’s, but it’s a distinct style — generally more approachable earlier, less reliant on new oak, and considerably better value per bottle.
Where to find it: Alexander Valley is the clear center of gravity here — Trione Vineyards & Winery is one of the family estates farming it — and see also our Jordan Winery visit guide for one of the region’s defining producers.
Sauvignon Blanc
Sauvignon Blanc is Sonoma’s fourth-largest crush at 13,533 tons, roughly 11% of the district. It doesn’t get the attention Chardonnay does, but it’s a genuine workhorse variety here, grown widely across the warmer valley floors.
Style-wise, Sonoma Sauvignon Blanc tends to split between a crisp, citrus-forward approach and a rounder, more textured style with some barrel influence. Neither is more “correct” — it’s worth trying both before deciding which you prefer.
Where to find it: Grown broadly across Dry Creek Valley, Alexander Valley, and Chalk Hill — Ferrari-Carano has poured a Dry Creek Fumé Blanc long enough to serve as a reference point for the barrel-influenced style.
Zinfandel
Zinfandel is Sonoma’s fifth-largest crush at 5,489 tons — just 4.6% of the district’s total tonnage, well behind the four varieties above it. But tonnage isn’t the whole story: Zinfandel commands a higher average price per ton ($3,125) than Chardonnay or Cabernet Sauvignon in this district — a reflection of old-vine premiums and buyer demand, not a claim about quality.
Dry Creek Valley is Zinfandel’s home in Sonoma, home to some of the oldest continuously farmed vines in California. These aren’t young plantings chasing a trend — many of the best examples come from vines planted 80 to 100+ years ago, farmed by the same families for generations.
Where to find it: Dry Creek Valley, where Dutcher Crossing Winery is one of the stops that makes the old-vine case well — see our wine weekend planning guide for a suggested Dry Creek itinerary built around it.
Merlot
Merlot rounds out the top six at 4,412 tons, about 3.7% of the district. It’s easy to overlook — Merlot fell out of fashion in the broader wine conversation years ago — but Sonoma still grows a meaningful amount of it, often in the same warm valleys that produce good Cabernet.
Well-made Sonoma Merlot is worth seeking out precisely because it’s not chasing a trend: what’s still being planted and replanted here is being kept around because growers and winemakers believe in it, not because it’s currently popular.
Where to find it: Alexander Valley, Dry Creek Valley, and Bennett Valley all produce it in smaller quantities alongside their headline varieties — Matanzas Creek Winery in Bennett Valley has stuck with the grape through the unfashionable years.
What This Means for Tasting
Knowing what’s actually grown here is only useful if it changes how you plan a visit. A few ways to use this:
- Tasting by variety: browse wineries by varietal to find tasting rooms pouring the grape you’re chasing.
- Tasting by region: pair this guide with our complete guide to Sonoma’s 19 AVAs — variety and place are inseparable here, and knowing both gets you to a better glass faster.
- Planning a weekend: if you’re building an itinerary around two or three of these varieties, our wine weekend planning guide has a structure that keeps you from over-scheduling.
