Rheingold Beer, introduced in 1883, is a New York beer that held 35 percent of the state's beer market from 1950 to 1960.
 The company was sold by the founding German American Liebmann family in 1963.
 According to the "New York Times," "Rheingold Beer was once a top New York brew guzzled regularly by a loyal cadre of workingmen who would just as soon have eaten nails as drink another beer maker's suds."
 Its VP-Technical Joseph Owades claims credit for Rheingold's developing the first light beer.

Bad Frog Beer is an American beer company founded by Jim Wauldron and based in Rose City, Michigan.
 Jim Wauldron did not create the beer to begin with.
 The company that Wauldron worked for was a T-shirt company.

 His boss told him that a frog would look too wimpy.
 Wauldron decided to call the frog a "bad frog."
 The idea sparked much interest.
 People all over the country wanted a shirt.
 The only problem with the shirt was that people started asking for the "bad frog beer" that the frog was holding on the shirt.
 Wauldron learned about brewing and his company began brewing in October 1995.
 The company has grown to 25 states and many countries.
 The beer is banned in eight states.

 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.
