Grappa is an alcoholic beverage, a fragrant, grape-based pomace brandy of Italian origin that contains 35 to 60 percent alcohol by volume (70 to 120 US proof). ==Overview== The flavour of grappa, like that of wine, depends on the type and quality of the grapes used, as well as the specifics of the distillation process. Grappa is made by distilling the skins, pulp, seeds, and stems (i.e., the pomace) left over from winemaking after pressing the grapes. It was originally made to prevent waste by using these leftovers. A similar drink, known as ''acquavite d'uva'', is made by distilling whole must. Grappa is now a protected name in the European Union. To be called grappa, the following criteria must be met: # Produced in Italy, or in the Italian part of Switzerland, or in San Marino # Produced from pomace # Fermentation and distillation must occur on the pomace—no added water Criterion 2 rules out the direct fermentation of pure grape juice, which is the method used to produce brandy. Criterion 3 has two important implications. First, the distillation must occur on solids. Thus, it is carried out not with a direct flame but with a bain-marie or steam distillation; otherwise, the pomace may burn. Second, the woody parts of the grapes (the stems and seeds) are co-fermented with the sugar-rich juice; this produces a very small amount of methanol, which is much more toxic than ethanol. Unlike in the similar process of making red wine, in grappa the methanol must be carefully removed during distillation. That is why there is an Italian law requiring winemakers to sell their pomace to grappa makers; this is a measure that was taken against moonshine operations, which are now very rare in Italy. In Italy, grappa is primarily served as a ''digestivo'' or after-dinner drink. Its main purpose is to aid in the digestion of heavy meals. Grappa may also be added to espresso coffee to create a ''caffè corretto'', meaning "correct" or "proper" coffee. Another variation of this is the ''ammazzacaffè'' ("coffee-killer"): the espresso is drunk first, followed by a few ounces of grappa served in its own glass. In Veneto, there is ''resentin'' ("little rinser"): after finishing a cup of espresso with sugar, a few drops of grappa are poured into the nearly empty cup, swirled, and drunk down in one sip. Among the best-known producers of grappa are Nonino, Bocchino, Berta, Sibona, Nardini, Jacopo Poli, Brotto, Villa de Varda, Domenis, Bepi Tosolini, and Distilleria De Negri. These grappas are produced in significant quantities and are exported; there are also many small local or regional grappas. Most grappa is clear, indicating it is an unaged distillate, though some may retain very faint pigments from their original fruit pomace. Lately, aged grappas have become more common, and these take on a yellow, or red-brown hue from the barrels in which they are stored. Use of the word grappa for product distilled in the United States is still allowed, and falls under the Class definition of Brandy further classified type as Pomace, specifically grappa or grappa brandy 〔(【引用サイトリンク】title=eCFR — Code of Federal Regulations )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「grappa」の詳細全文を読む スポンサード リンク
