Sunday of September. Wine The three neighbouring Provinces of Asti, Cuneo, and Alessandria incorporate the Langhe and Monferrato Hills region in the centre of Piedmont, limestone and sandstone deposits laid down by the retreating Adriatic some 5 million years ago, and are home to some of Italy's most known red wines, plus some white ones. Asti is the center of production of the sparkling Asti (DOCG, often known as Asti Spumante). Asti is typically sweet and low in alcohol (often below 8%). It is made solely from the moscato bianco white muscat grape. Other wines include a premium version known as Moscato d'Asti (DOCG) and the red Barbera. The first products from the province of Asti to become known internationally are Martini and Rossi, Gancia and Riccadonna, which made commercial wines like Asti Spumante; red wines such as Barbera d'Asti, Freisa d'Asti, Grignolino d'Asti, Bonarda, Grignolino and Ruché di Castagnole Monferrato are also becoming widespread worldwide. These wines and many others can be sampled during the week-long Douja d'Or wine exhibition which is held at the same time as the Palio and Sagre. The first documentation on the variety Freisa d'Asti are from the beginning of the 16th century. Food Asti is also famous for its Asti's Festival of Festivals, held in September a week before the Palio. During the festival most of the towns in Asti's province meet in a great square called "Campo del Palio", here they offer typical food and wine for which they are known. On the Sunday of the Sagre all the towns involved stage a parade with floats depicting traditional farming with everyone in costume along Asti's roads to reach "Campo del Palio" square. Asti province becomes a gourmand's delight from October to December in the white truffle or "tartufo bianco" season. Although neighbouring Alba is better known for its October truffle fair, some of the best truffles are found around Asti's hills, and every weekend there is a local truffle festival. Sport The main football club of the town was Asti Calcio F.C. (ex-A.C.D. Asti), which folded in 2017. Another football club, A.S.D. Colline Alfieri Don Bosco (ex-A.C. Celle, from Celle Enomondo), relocated to the city and was renamed to "A.S.D. Alfieri Asti" in 2017. Since 2019 it was known as A.S.D. Asti. Former futsal league champion, A.S.D. Asti Calcio a 5 is also based in Asti. Transport Asti railway station, opened in
