US wine distributor Wilson Daniels has added labels from Sonoma Valley winery Gundlach Bundschu to its portfolio.

The two companies announced the agreement yesterday (7 August). Gundlach Bundschu head Jeff Bundschu said the deal would help build national awareness of the company's wine after several years of investment.

"I have never been more confident in the quality of Gundlach Bundschu wines," he said. "Our partnership with Wilson Daniels will raise the quality standard of our distribution while allowing us to focus on what we do best - growing and making great wine."

The winery produces 35,000 cases of wine a year, primarily Gewurztraminer, Chardonnay, Pinot Noir, Merlot and Cabernet Sauvignon.

Andy Fromm, president and COO of Wilson Daniels, said: "We are excited about the future of Gundlach Bundschu and Jeff's visionary leadership, as the winery melds its rich history and quality, estate-focused wines with a spirited and irreverent culture that is both fun and infectious."

Financial details of the deal were not disclosed.
