With a varied geography, many different micro-climates and a vast array of grape varieties and viticultural traditions, it is not surprising that Italy can offer a full range of sparkling wine in all styles and quality. The Spumante wines of Piedmont, centred around the town of Asti, are the best known; These are usually medium dry and sweet sparkling wines made by the tank method from Moscato grapes. The drier Prosecco Spumante is produced in the Veneto region from Glera grapes using the same tank or transfer method. The cooler Alpine regions are the source of Italy`s finer method traditional sparkling wines, often including blends of Chardonnay, Pinot Blanc and Pinot Noir. Tank fermented sparkling wines are produced in many other of Italy`s warmer regions.
