Since it is natural and bottled without gas, it produces a weak carbonation, and when Asturian cider is served, it is poured in a particular way, "el escanciado": the bottle is held above the head allowing for a long vertical pour, causing the cider to be aerated as it splashes into the glass below. After drinking most of the content, it is customary to splash a little out onto the ground, as a way to clean the glass of any lees for the next serving. Traditionally, the same glass is refilled and passed around, with everyone drinking from it in turn. Asturian cheeses, especially Cabrales, are also eaten throughout Spain and beyond; Asturias is often called "the land of cheeses" ("el país de los quesos"). Asturias has two main football teams: Sporting de Gijón and Real Oviedo, which have played over 35 seasons in La Liga. Other current notable sports teams are Oviedo CB (basketball) and AB Gijón Jovellanos (handball). Racecar driver Fernando Alonso is a two-time Formula One world champion, and races with Asturias' flag colours on his helmet. Also, cyclist Samuel Sánchez won a gold at the Olympic games. Football players from Asturias include World Cup winner David Villa as well as Quini, Luis Enrique, Juan Manuel Mata, and Santiago Cazorla, among others. These are some notable people of Asturian Literature:  The music of Asturias is varied. The most characteristic instrument in traditional music is the Asturian bagpipe, or "Gaita asturiana", which has a single drone, in common with the traditional bagpipes of other Celtic nations such as Wales and Ireland. The bagpipe is often accompanied by the hand drum, whistles and accordion. In recent years, there has been a resurgence of interest in traditional folk music, and several music ensembles have gained regional and international recognition for their ethnomusicological study and presentation of indigenous Asturian music. Notable examples include traditional pipers such as Xuacu Amieva and Tejedor and fusionist José Ángel Hevia (whose music video provides views of both the gaita and the Asturian landscape), and the groups Llan de Cubel, Xera, Nuberu and Felpeyu. Additionally, numerous rock, ska and heavy metal groups have also found relative success within Asturias, many of which incorporate elements of traditional Asturian music into their sound.
