The rising cost of Beer

It appears as though an abnormally hot year, causing an abnormally lower crop yield will result in the rising cost of bread, pasta and beer.These are three staples in my diet.

On a side note; the article also mentions corn. Corn, the miracle grain that we're going to turn into ethanol in order to run our cars on something other than a petroleum product, and break our addiction to middle east oil. Does anyone else see this and make the following connection(s)? Corn crop yield is used for making ethanol. Corn crop yield is also directly proportional to the amount of fertilizer used. Most fertilzers are petroleum based. We're not any further ahead using ethanol. This technology seems doomed.
