Really quite a nice article on Ste Michelle.
Ste. Michelle Wine Estates, currently the 10th largest wine company in the United States, is a collection of wineries that includes Chateau Ste. Michelle and Columbia Crest, as well as Washington-based wineries Snoqualmie, Northstar and Spring Valley Vineyard, and a couple of joint international ventures, such as Col Solare (with Italy’s Piero Antinori) and Eroica (with Germany’s Ernst Loosen); there are also partnerships with California wineries like Conn Creek and Villa Mt. Eden, and Oregon’s Erath Vineyards. Every one of these wineries has its own market position and production facilities; the company clearly wants them to maintain their individual identities.
