Until the early 1990s, Brau und Brunnen was the largest beverage company in Germany, but its market share steadily declined throughout the 1990s. An additional cause for the decline was the company's purchase of Bavaria – St. Pauli Brewery and Jever for an estimated 800 million DM, although these purchases were later estimated to only be worth closer to 250 million DM. Other companies engaged in a series of mergers and acquisitions, and by 1999, it had sank to the fourth-largest beverage company and was continually losing money.

Document 11: 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.
