2016 Sonoma Vintage

The 2016 growing season in Sonoma was broadly characterized by moderation rather than adversity. An early budbreak in some areas, triggered by warm February temperatures, set up a long season. Spring rains during flowering reduced cluster size in certain vineyards, naturally limiting yields. The key feature of the vintage was an unusually cool August, locally described as 'Fogust,' when foggy mornings lingered well into the afternoon and temperatures ran roughly 10 degrees below average, allowing fruit to ripen slowly without dehydration or premature sugar accumulation. September brought cool mornings and warm, sunny afternoons without excessive heat, and most producers completed harvest by late September before early October rains arrived.

• Early budbreak in parts of Sonoma from late January to early February, following a mild winter
• Spring rain during flowering produced smaller berries and clusters but did not cause widespread frost damage
• August was exceptionally cool, described by Jordan Winery as one of the most moderate growing months in a decade
• Rains arrived mid-October, creating pressure for any remaining late-ripening Cabernet Sauvignon and Syrah

Russian River Valley emerged as a standout, with the cool marine-influenced summer providing ideal conditions for slow phenolic development in Pinot Noir and Chardonnay. The lack of heat waves kept sugar levels and phenolic maturity in sync, producing wines with genuine complexity and balance. Sonoma Coast benefited similarly, with ocean-driven cooling delivering precise, structured Pinot Noirs. Alexander Valley and Dry Creek Valley saw their Cabernet Sauvignon and Zinfandel ripen steadily through a warm late season, with Rodney Strong's winemaker noting that Bordeaux varietals showed great structure, tannin profile, and intense color and flavors.

• Russian River Valley Pinot Noir: polished tannins from slow vine maturation, bright acidity, red and dark cherry fruit
• Sonoma Coast Pinot Noir: structured and precise, shaped by ocean influence and cool temperatures throughout the summer
• Russian River Valley Chardonnay: lemon oil, pear, and stone fruit with creamy richness balanced by bright acidity
• Alexander Valley and Dry Creek Valley reds: steady ripening, good structure, and strong color intensity

Several established Sonoma producers excelled in 2016. Kosta Browne, founded in 1997 and based in Sebastopol, released a 2016 Sonoma Coast Pinot Noir showing baked berry, cacao, and spice aromas with loganberry and plum on a silky-tannined palate. Emeritus Vineyards produced a verified 2016 Hallberg Ranch Pinot Noir from their 120-acre Russian River Valley estate, with community reviews averaging around 90 points. Dutton-Goldfield, the partnership between Steve Dutton and Dan Goldfield founded in 1998, released a 2016 Dutton Ranch Chardonnay showcasing pear, lemon oil, brioche, and roasted chestnut with bright balancing acidity, as well as a 2016 Dutton Ranch Pinot Noir of deep black cherry, plush black raspberry, and rhubarb earthiness.

• Kosta Browne 2016 Sonoma Coast Pinot Noir: verified release showing baked berry, cacao, spice, loganberry, and silky tannins
• Emeritus 2016 Hallberg Ranch Pinot Noir: estate Russian River Valley wine from 120-acre vineyard planted to Pommard and Dijon clones
• Dutton-Goldfield 2016 Dutton Ranch Chardonnay: lemon oil, pear, brioche, and mouthwatering freshness; a showcase of the vintage
• Dutton-Goldfield 2016 Dutton Ranch Pinot Noir: described as both rich and lively, with juicy blackberry, redwood, and spice box

By 2026, most 2016 Sonoma Pinot Noirs and Chardonnays are in or approaching their peak drinking windows. Williams Selyem noted that 2016 wines exhibit wonderfully polished tannins from long, slow grape maturation, and the best examples have continued to reward patience. K&L Wines observed that the wines 'show focus, delineation, and a terrific upside' and may demand a bit more patience than immediately generous vintages. Top Russian River Valley Pinot Noirs from skilled producers are likely showing evolved complexity now, while Chardonnays from the vintage are generally approaching the end of their optimal window. Alexander Valley Cabernet Sauvignons, harvested with excellent structure and concentration, may still offer a few more years of pleasure.

• Russian River Valley Pinot Noir: peak or approaching peak in 2026; earlier-harvested examples may be fading
• Sonoma Coast Pinot Noir: structured wines from top producers may still benefit from holding through 2027 or beyond
• Russian River Valley Chardonnay: drink now; best examples remain fresh but further aging offers diminishing returns
• Alexander Valley Cabernet Sauvignon: approachable now, with the best structured examples holding through 2028

The 2016 season's moderate temperatures kept sugar levels and phenolic maturity developing in tandem, which winemakers regarded as ideal. Arista winemaker Matt Courtney described ripening as 'slow and predictable,' and Martinelli's Bryan Kvamme noted that the absence of prolonged extreme heat events allowed for the gradual accumulation of flavors rather than reacting to rapidly climbing Brix. Jordan Winery reported Chardonnay harvested at an average of 23.4 Brix, with fruit arriving in pristine condition. Dutton-Goldfield used traditional open-top fermentation for Pinot Noir with cold-soaking for color and flavor, and aged in 40 percent new French oak barrels. The balanced natural acidity meant malolactic fermentation decisions were less fraught than in riper years.

• Jordan Winery reported 2016 Russian River Valley Chardonnay harvested at an average of 23.4 Brix, with pristine fruit condition
• Lack of heat waves kept sugar and phenolic maturity in sync, reducing the need for corrective interventions
• Dutton-Goldfield: open-top fermentation with cold soak, skin contact 14 to 20 days, aged in 40 percent new French oak
• Slow, even ripening produced wines described by DuMol winemaker Andy Smith as 'very pure, with strong specific vineyard signatures'

The 2016 Sonoma vintage is not a dramatic, high-tension year but rather a quietly excellent one that rewards those who sought out skilled producers. Its character lies in balance, delineation, and consistency across price points and varieties, which is rare. For collectors and students of California wine, 2016 offers a useful contrast to the very small, drought-stressed 2015 vintage and the heat-challenged 2017. The vintage demonstrates what a moderate, fog-cooled Sonoma summer can deliver: wines of genuine elegance and site expression rather than extraction and power. Focus on Russian River Valley and Sonoma Coast for Pinot Noir and Chardonnay, and seek out producers with strong reputations for vineyard-designated bottlings.

• Best for: collectors seeking balanced, site-expressive Pinot Noir and Chardonnay with genuine aging potential
• Broader strength than most: quality is consistent from entry-level to prestige bottlings, unlike more selective vintages
• Compare with 2015: 2016 yields were far more normal after 2015's dramatically reduced Pinot Noir crop
• Avoid expecting blockbuster power; 2016 Sonoma rewards patience and rewards those who value restraint and complexity
