After years of making wine, beer and spirits brands for others, Novato-based WX has taken a much bigger step into having its own branded portfolio with the purchase of two Napa Valley-produced wines.

Maker of more than 80 exclusive brands retailers globally, WX on Tuesday, April 4, said it acquired the Jamieson Ranch Vineyards portfolio and the Bread & Butter brand. The company claims the deal now makes it among the top 20 U.S. wine suppliers.

The Bread & Butter brand has been made at south Napa custom winery Fior di Sole for Carmel-based Alcohol by Volume Family of Wines. WX said it plans to expand the California chardonnay and pinot noir brand’s distribution for across the U.S.

“This is one of the hottest brands in the wine industry,” said Oren Lewin, WX senior vice president of marketing and strategy. “Bread & Butter grew over 70 percent in 2016. It has really struck a chord with consumers.”

Introduced in July 2013, Bread & Butter makes wines in the fast-growing superpremium price category — $12–$15 a bottle. Dollar sales volume in food and liquor stores increased 139 percent for the 52 weeks ended Feb. 25, according to Nielsen data cited by the WX acquisition team.

Santa Rosa-based Zepponi & Company was the exclusive financial adviser to the sellers of Bread & Butter.

Bill Leigon of Rex Goliath wine brand fame and Bill Spears purchased acquired the Kirkland Ranch Winery brands and inventory in September 2015 and renamed it after the Jamieson family that had long farmed the canyon corridor between Napa Valley and Solano County. The property is part of a land grant that dates back to California statehood.

At the same time as the Kirkland Ranch brand buy, Ken Laird of Laird Family Estate acquired the winery and surrounding vineyards on Jameson Canyon Road.

The Jamieson Ranch Vineyards line of wines includes Double Lariat, Reata, Whiplash and Light Horse.

Started 17 years ago as a business-to-business online supplies portal called Winery Exchange, WX quickly morphed into a producer of exclusive brands. In the past few years, the company has shifted into producing its own brands, acquiring Chronic Cellars, an up-and-coming winery from Paso Robles, and Our Daily Wines, a leading brand of preservative-free wines.
