Sonoma Coast


The Russian River Valley climate is defined by its proximity to the ocean and is bordered by the Russian River and the Mayacamas mountains. Coastal breezes bring cooling fog through the Petaluma wind gap in the morning and evening, balancing the afternoon heat enjoyed in this appellation. This temperature differential creates excellent conditions for our Chardonnays as the fruit is afforded a long growing season, allowing time for optimum fruit maturity.

The Purrington Rued Vineyard, Ritchie Vineyard, and Dutton Ranch Sebastopol Vineyards are the fruit sources for our vineyard designated Chardonnays and our True Course, The Voyage, and Absolutely Eloise Chardonnays. The fruit from each of these vineyards comes from very old vines which lends the complexity and intense fruit flavors which are key to the composition of these memorable Chardonnay wines.

Recent Critical Acclaim

Chateau Boswell True Course Chardonnay 2016; Getting a few expletives in the notes, the 2016 Chardonnay True Course is a heavenly Chardonnay that's sourced from the Rued, Ritchie, and Sebastopol Vineyards in Sonoma County. Caramelized orchard fruits, honeysuckle, orange marmalade, and a honeyed minerality all soar from the glass of this opulent, rich, textured effort that hits the palate with full-bodied richness, yet never seems heavy or cumbersome in the least. Possessing terrific acidity, a concentrated, layered mid-palate, and an undeniable minerality, this beauty will be better with a year in bottle and keep for 10-15 years. 98 points Jeb Dunnuck

Chateau Boswell Absolutely Eloise Russian River Valley Chardonnay 2016: Another wine that has a Chablis-on-steroids style, the 2016 Chardonnay Absolutely Eloise boasts a huge nose of lemon curd, poached pear, oyster shell, and white flowers. It's powerful and full-bodied, yet as with all of these releases from Boswell, has a vibrant, elegant, lively style that goes on and on in the finish. This release comes 50% from Sebastopol Vineyard, 30% from Rued Vineyard, and the rest from Ritchie Vineyard, and was fermented and aged in 70% new French oak. 97 Points Jeb Dunnuck

Chateau Boswell Dutton Ranch Sebastopol Vineyard Chardonnay 2016: The 2016 Chardonnay Sebastopol Bursts forth with gregarious white grapefruit, yuzu and lemonade notes with touches of lime cordial, white blossoms, white peaches and chalk dust plus a hint of marzipan. The concentrated, full-bodied palate is packed with tightly wound citrus and mineral layers marked by a crisp line, finishing very long. 96+ points RP Wine Advocate

Chateau Boswell Purrington Rued Vineyard Chardonnay 2016: The 2016 Chardonnay Purrington-Rued Vineyard opens with a rock-star nose of ripe apricots, beeswax, warm melons, guava and honeysuckle with touches of nutmeg, aniseed, baking bread and orange blossoms. The medium to full-bodied palate is bold and decadently fruited with tons of tropical fruit layers and just enough freshness, finishing long and spicy. 95+ RP Wine Advocate

Chateau Boswell Ritchie Vineyard Chardonnay 2016: The 2016 Chardonnay Ritchie Vineyard, aged in 70% new French oak for 16 months, is a little reticent to begin, offering glimpses at apple tart, ripe bosc pears and honeydew melon notes with suggestions of toasted almonds, musk perfume, lanolin and wet pebbles. The palate is medium to full-bodied with a lively backbone of freshness lifting the taut, mineral-accented fruit, finishing very long. 95+ RP Wine Advocate


The beautifully managed Sun Chase vineyard offers everything Pinot Noir needs to achieve perfection. High above the fog line at a 1400 foot elevation on Sonoma Mountain at the confluence of the Petaluma Gap is the location of the Chateau Boswell block. Early morning sun provides a full day of sun exposure while the cool ocean breezes protect the fruit from too much heat. This allows for a long growing season providing us with fully ripe rich fruit for maximum flavor components.
