Copain Winery Fermentation Facility, Healdsburg, Calif.

Owned by Copain Wine Cellars LLC, the Copain Winery distributes top-quality wines across the United States. The company uses "Old-World" techniques in its wine making to avoid little intervention in its process. This technique employs natural primary and malolactic fermentations without the addition of cultural yeasts and bacteria, creating wines that are bottled unfined and unfiltered to avoid any stripping of flavors or aromas that are characteristic of the source vineyard. The Copain Winery produces wines that allow for a unique expression of each vineyard's qualities and characteristics while creating a wine that is complementary to food.

For this project, the Metallic Building Co.'s pre-engineered metal buildings that were incorporated on the 20 acres (8 hectares) of land also needed to fulfill the company's approach to wine making.


The first metal building houses the fermentation tanks, while the other holds the barrels in which the grapes are crushed and processed. Both buildings are lean-to structures that total 10,000 square feet (929 m2). The fermentation storage building is 32 3/4 feet by 127 11/12 feet by 20 1/2 feet (10 m by 39 m by 6 m) and the second building is 33 3/4 feet by 75 1/3 feet by 20 1/2 feet (10 m by 23 m by 6 m). Both buildings incorporate Lokseam roof panels and PBC endwall and sidewall panels by Metallic Building. The Lokseam roof, in a Signature 300 Colonial Red Kynar finish, was installed over 4-inch (102-mm) API and was chosen for its low maintenance and aesthetics. Other metal accessories in the project included large peak skylights, chosen for their energy efficiency.

Construction took place between June and November 2007.
