What is BPA, and do Sierra Nevada cans have a liner containing BPA?

BPA (Bisphenol A) is a chemical that is found in trace amounts in the protective epoxy liner used to coat many food grade surfaces. Almost all cans (food, soda, and beer) have this type of epoxy liner which is designed to maintain the flavor integrity and freshness of product. For us, the liner has an important role: keeping beer from coming in contact with the metal, which could impact beer flavor. BPA is a chemical that has shown to be toxic in high doses. Although opinions vary as to the risk, some studies show that you’d have to eat and drink the contents of roughly 450 cans per day, every day, to ingest enough BPA from a can liner to reach unsafe levels. However, we encourage you make the best decision for you. Sierra Nevada can liners do contain trace amounts of BPA because there is currently no alternative for beverage container liners. The industry is focused on developing a satisfactory alternative to the current liner technology, but so far none has been found to meet the performance and safety of the materials currently available. We have diligently petitioned our can manufacturer to develop a liner that doesn’t contain any measurable BPA and would protect the flavor of our beer. We are one of the first companies in line to use a BPA-free liner as soon as it’s available. In our opinion, the benefits of cans—portability, lower carbon footprint, recyclability, and absolute protection from light and oxygen—outweigh the risk.
