Let’s say that you drink local beer because you think it is important to support locally produced products and further the environmentally correct thing to do.
So there’s every chance you expect the local brewery to use local products itself. But what if it is much cheaper for the contract mobile bottling company which happens to be called “Green Bottling” that packages the beer for the brewery to buy from China or Oklahoma than from a plant three miles away.
Kind of complicated, I know. You’ll find the discussion at the Oregon Economics Blog.
