Bottoms up to Joseh Groll! "On October 5, 1842 Czech brew master Josef Groll discovered a unique bottom fermenting process known as “lagering” and birthed the world’s first golden beer. From that day forward, Pilsner Urquell, which translates to “from the original source, Plzen” has been the standard against which all others beers are compared. Today, nearly 90 percent of the world’s beer is a variation of the original golden beer, making pilsner the most popular beer style in the world and further establishing Pilsner Urquell as a true original." http://www.2beerguys.com/blog/2008/09/25/pilsner-urquell-celebrates-its-birthday-on-october-5th%E2%80%8F/ Aug 10 09, 12:38 PM
