For many large companies, sustainability can be a buzz term, a simple marketing ploy for sympathy and sales. For Sierra Nevada, the widely-distributed craft beer out of Chico, California, sustainability actually appears to mean something. We stopped in Sierra's headquarters to see what environmental brewing looks like. Many of the raw ingredients (hops and barley) are sourced locally or via ultra-efficient shipping routes. Recycled paper is used for packaging. And the roof of the facility is covered with more than 10,500 solar panels—one of the largest privately-owned solar installations in America.
