As an avid beer lover, the following is provided without further comment from the December edition of the Bulletin of the American Meteorological Society:
"...Researchers have found that warmer temperatures are threatening the quality of beer. A team led by Martin Mozny of the Czech Hydrometeorological Institute compared data on weather patterns, crop yield, and hop quality in the Czech Republic from 1954 to 2006 to determine the effects of climate on the quality of Saaz hops, which are used to make pilsner lagers. They found that the concentration of alpha acids in the hops had decreased by 0.06% per year during the studied period. Alpha acids give the Saaz hops their unique bitter taste, and the scientists attribute their decline to changing growing conditions and other effects they relate to increasing temperatures in the region. The study was recently published in Agricultural and Forest Meteorology."
