Sonoma Wine Facts
Sonoma County, adjacent to Napa Valley, is one of the most diverse wine regions in the world. It boasts towering mountains, 50-plus miles of Pacific coastline, oak-studded hills, and sun-kissed valleys - which gives it a wide variety of terrain and climate within its wine-growing regions.
Sonoma Wine Country lays claim to being the birthplace of California's modern wine industry and has the state's oldest premium winery (Buena Vista) and the oldest, continuously operating family winery (Gundlach-Bundschu). In 2019, it was named the Wine Region of the Year by Wine Enthusiast magazine.
Great wine begins in the vineyard and Mother Nature blessed Sonoma County with the amazing combinations of topography, microclimates, and soil types, all of which create 18 American Viticultural Areas (AVAs, or appellations) - regions with unique soils and climates that allow 60+ grape varieties to grow particularly well.

Sonoma County has a diverse landscape of terroir and microclimates that make way for over 64 different varietals to be grown in the 18 AVAs across the county. Although wines can be made in many different styles, some flavors and characteristics are common to these predominantly planted grape varieties. This list is in the order used during a wine-tasting experience - lightest to boldest.
Sauvignon Blanc: Crisp and lively, with citrus flavors, a slight grassiness, medium to high acidity, and little or no oak influence.
Chardonnay: Can run the gamut of styles from crisp and minerally to creamy and buttery. Yellow apple, vanilla and lemon are common descriptions. Chardonnay responds well to oak, so many have toasty, spicy flavors as well.
Pinot Noir: Nuanced and ethereal, Pinot Noir is an elegant wine that can be surprisingly structured, offering flavors of red and black cherries, raspberries, and a hint of earthiness.
Merlot: Plump, ripe fruit, smooth tannins, and flavors of red and black cherries and red currant characterize this popular grape. Can range in structure from soft and approachable to intense and almost as structured as Cabernet Sauvignon.
Zinfandel: Known for its spicy pepperiness, jammy blackberry fruit, and brambly characteristics. Usually medium to full-bodied wines that aren't overly tannic.
Syrah: Fast growing in popularity, Syrah grows well in almost all of Sonoma County's wide-ranging climates. In the warmer areas, it exhibits rich black fruit, mocha, and spice flavors, while cooler climates allow for longer hang-time on the vine that brings out the wine's acidity and pepperiness.
Cabernet Sauvignon: One of the most widely planted red grapes in Sonoma County, Cabernet is concentrated and structured, with flavors of black currant, anise, and cedar. Often best after a few years of aging.
