Sonoma, Calif.—The Chilean cooperage that sold barrels under the Toneleria Nacional and Mistral Barrels brands, has changed its name to TN Coopers. The name change comes as the company also recently completed a new cooperage in the Casablanca Valley of Chile. The company claims its new cooperage represents one of the largest investments in the Chilean wine industry in recent years. TN Coopers operates in the U.S. from a Sonoma, Calif. office.
