June Mountain Vineyard

A 1990 Haas School MBA, Michael Bloch had a 30-year career in the information technology field, ultimately becoming CIO for his wife June Ressler’s global consulting firm. Looking ahead to retirement, in 2013 June and Michael purchased 100 hillside acres in the Fountaingrove District AVA of Sonoma County. They planted 22 acres with multiple grape varieties to sell to other wineries, reserving one acre for themselves. Upon tasting the wines made from those grapes, what started as a hobby became a business, and the June Mountain Vineyard brand was established. The first vintages were field blends of the five red bordeaux varieties plus zinfandel and syrah, but as yields grew, they concentrated on single-vineyard cabernet sauvignon and zinfandel varietal releases.

Tasting Notes
A beautiful wine, with aromas of plums, cherries and pepper. This structured zinfandel lingers on the palate, yet a smooth peppery finish is what makes this wine a classic. The mouthfeel is juicy, and leaves us wanting another sip. This wine is delicious now but will age for another 5 years.

Brown Estate is the first Black-owned estate winery in the Napa Valley. Located in the hills east of Rutherford, the remote property was purchased in 1980 by Bassett & Marcela Brown. Between 1981–1990 they restored the long-abandoned homestead and planted vineyards that gave rise in the mid-90s to an eponymous wine label founded by next-gen siblings Deneen, Coral, and David Brown, whose first offering was 700 cases of 1996 Brown Estate Zinfandel. The Brown lineup has expanded over time to include cabernet sauvignon, chardonnay, petite sirah, and a popular red blend known as Chaos Theory, along with a suite of single vineyard zinfandels and numerous small lot specialty wines. You can follow @brownestate on Instagram and/or visit their Brown Downtown Napa tasting room by appointment.

2021 Chaos Theory Red Blend

Tasting Notes
Chaos Theory began as a one-off and, back then, irreverent blend of cabernet sauvignon and zinfandel that David created for our first participation in the annual Premiere Napa Valley trade auction some 15 years ago. After it made a splash, he went back to the cellar to incorporate details so we could make it a permanent part of our lineup. Over the years, though, Chaos Theory has become a shape-shifter, each vintage its own unique blend reflecting the nature of our journey in the world of wine—a constant adventure that reminds us year in and year out that no matter how random or chaotic conditions may seem, amidst the mayhem there is reason, if not always rhyme… and from each season, great wine. This is vintage no. 17.

I was born in the United States shortly after my  parents and sibling moved here from Paris. As was the tradition in France, I grew up having water with a splash of red wine with dinner from an early age. Soon after graduating from Cal, I was reintroduced to wine by a sommelier friend and soon developed a passion for expanding my wine knowledge and developing my palate. That passion eventually led my wife and me to buying a small plot of land in Sonoma in 2015 and planting vineyards with pinot noir and chardonnay. My goal was to make a Burgundian style pinot from the Russian River Valley—light-bodied with complex flavors and a mouth pleasing finish. We hope you will enjoy it!

Tasting Notes
Desforges Vineyards is a small family estate nestled in a peaceful valley near the historical town of Healdsburg in Sonoma County. The vineyards were planted with a combination of two pinot noir clones, pomard (deep dark fruit notes) and martini (bright red fruit notes), giving the wine a balanced and complex character typical of the Russian River Valley. The grapes were hand-picked and sorted, vinified with a light hand, then aged for 20 months in French oak. The result is a Burgundian-style pinot noir reflecting the French heritage of the Desforges family. We hope you enjoy our wine! Santé!
