Fossil Fuels Brewing Company is a beer maker based in Manteca, California, United States. The beer is brewed with ancient yeast that medical mycologist and co-owner Raul Cano extracted from amber and revived after 25 to 45 million years. The company launched a German-style wheat beer in the Northern California area on July 27, 2008. The process that the company used to extract yeast from amber is similar to the process described in the fictional book Jurassic Park that was used to retrieve dinosaur blood from mosquitos trapped in amber. The beer has received mixed critical reviews, including that it has a unique taste.
