I'm sure that you've noticed beer is getting more expensive. There are lot of factors that go into the cost of beer and all of them seem to be costing more and more. One factor, though, seems to come out in every news piece I read; farmers are turning to corn. Growers of hops and barley are increasingly switching to corn as the demand for ethanol continues to go up.
Where will this go? I have no idea but it seems to me that there should be a tipping point when the prices of barley and hops will be so high that the farmers will start growing them again. In the meantime, though, hang on; it's going to be a bumpy ride!
