Beer in Mexico: Beer in Mexico has a long history.  While Mesoamerican cultures knew of fermented alcoholic beverages, including a corn beer, long before the Spanish conquest, European style beer brewed with barley was introduced with the Spanish soon after Hernán Cortés’s arrival.  Production of this beer here was limited during the colonial period due to the lack of materials and severe restrictions and taxes placed on the product by Spanish authorities.  After the Mexican War of Independence, these restrictions disappeared, and the industry was permitted to develop.  Furthermore, the arrival of German immigrants and the short-lived empire of Austrian Maximilian I in the 19th century provided the impetus for the opening of many breweries in various parts of the country.  By 1918, there were 36 brewing companies, but over the 20th century, the industry consolidated until today, only two corporations, Grupo Modelo and FEMSA control 90% of the Mexican beer market.  This industry is one of the most prevalent in the country, with over 63% of the population buying one brand or another.  Beer is also a major export for the country, with most going to the United States, but is available in over 150 countries in the world.

Weyerbacher Brewing Company: Weyerbacher Brewing Company is a brewery in Easton, Pennsylvania, United States, founded in 1995 by Dan and Sue Weirback.  The brewery is well known for its "huge taste" beers.  Most of their brews are high in alcohol, with QUAD clocking in at 11.8% alcohol by volume, and a one-off 10th anniversary ale called Decadence brewed to 13% alcohol by volume.  Hops Infusion is one of the bitterest examples of the IPA style.  Weyerbacher is also a pioneer of aging beer in wooden barrels previously used for aging bourbon.  This process was used to transform Old Heathen imperial stout into Heresy, Blithering Idiot barley wine into Insanity, Merry Monks Belgian tripel into Prophecy, and QUAD Belgian quadrupel into Blasphemy.  These four styles are all very high-alcohol brews with complex flavor profiles; the barrel-aging lends additional oak and whiskey flavors.  The results have been widely praised by fans of huge beers, though persons accustomed to more mainstream beer may find them an acquired taste.

In upper level of vessels with the edges in the wine floated barley, and there was stuck a reed, large and small sizes and who wanted to drink, had to taken a reed in his mouth and pull it through the wine.  Not mixed with water, the wine was very strong, but for local people it was a very pleasant drink".
