I lost count at about a dozen. There have been an abnormally high number of coffee shops closing recently. Just this morning reading the comments on Arizona Coffee I learned that Areopagus Coffee has closed its store and decided to focus efforts on coffee roasting. Its made me ponder the future of coffee shops in Arizona, and quite a bit of the discussion on this site has been about that as well lately. Warren Buffett often talks about diversification. He has been wildly successful because of his ability to invest in many different business types. Is it time for coffee shops to diversify? To break out into new areas? Can a coffee shop just serve coffee and really be successful in Arizona in the summertime? Coffee shops have tried everything from serving a full food menu, to operating a gelato lounge on the side. In a few cases we have wine bars and live music events. Scottsdale based Intatto Coffee even serves pizza and I hear it is quite popular. I don’t have the answers, but it’s an interesting discussion topic. Should coffee shops in Arizona diversify?
