Growing Mushrooms

A Combination of Art & Science

At Premier Mushrooms we produce over 15 million pounds annually in our 64 growing rooms located in the agriculturally rich region of the Colusa Valley, just north of Sacramento. The pasteurization processes take place in a fully enclosed wharf area. The covered wharf provides several benefits which can be seen in the final product.
