to keep the heat in, and covered with plenty of soil. Alcoholic beverages Though wine (vino) has traditionally been the most popular alcoholic beverage in Argentina, beer (cerveza; the Italian birra is frequently used) in recent decades has competed with wine in popularity. Breweries appeared in Argentina at the end of the 1860s, started by Alsatian colonists. The first were nearly all in the downtown of Buenos Aires (el égido de la Ciudad Autónoma de Buenos Aires), and soon Polish brewers began industrial production of beer: San Carlos in the province of Santa Fe, Río Segundo and Córdoba in the province of Córdoba, Quilmes and Llavallol on the outskirts of La Plata (in Buenos Aires Province), San Miguel de Tucumán in the province of Tucumán and on the outskirts of the cities of Mendoza and Salta. The local consumption of beer has risen dramatically in the last generation: Argentines consumed 233 million litres in 1980 and 1.57 billion in 2007 (40 litres per capita). Outpacing that of wine since 2001, the growing production and consumption of beer have supported the existence of related events, for example, beer festivals called Oktoberfests or "Fiestas de la Cerveza" in locations that have a significant German population (Villa General Belgrano in Córdoba, San Carlos and Esperanza in the province of Santa Fe, etc.). Such celebrations copy, in an Argentine manner, Munich's Oktoberfest, and similarly are tourist attractions. However, the presence of a vigorous population of Celtic lineage, principally of Irish origin, has supported the creation of other celebrations of beer, often for marketing purposes, such as Saint Patrick's Day (Día de San Patricio), patron of Ireland, which is celebrated with abundant libations. The consumption of alcoholic beverages in Argentina is similar to that of the United States and somewhat lower than the Western European average. Argentines enjoy a variety of alcoholic beverages and Argentina can boast a varied array of elaboraciones, whether industrial or artisanal. Besides beer and wine, Argentines frequently drink cider (here again, the heritage comes from Spain and Italy, more precisely from Asturias and Campania). Cider is the most popular beverage of the middle and lowers economic classes at Christmas and New Year (the upper classes proverbially preferring to celebrate with locally produced champagne, although real old-line "creole" aristocrats will still drink cider, which is much more traditional). Other widely consumed spirits are aguardiente (firewater) made from sugar cane, known as
