Cheesemaking is an ancient tradition in most Alpine countries. A wheel of cheese from the Emmental in Switzerland can weigh up to 45 kg (100 lb), and the Beaufort in Savoy can weight up to 70 kilograms (150 lb). Owners of the cows traditionally receive from the cheesemakers a portion in relation to the proportion of the cows' milk from the summer months in the high alps. Haymaking is an important farming activity in mountain villages which has become somewhat mechanized in recent years, although the slopes are so steep that usually scythes are necessary to cut the grass. Hay is normally brought in twice a year, often also on festival days. Alpine festivals vary from country to country and often include the display of local costumes such as dirndl and trachten, the playing of Alpenhorns, wrestling matches, some pagan traditions such as Walpurgis Night and, in many areas, Carnival is celebrated before Lent.
