葡萄酒與食用水果葡萄不同：釀酒的葡萄較小，甜度較高，種子很多。大多數葡萄酒都是由一種起源於高加索的葡萄品種葡萄釀製而成的。葡萄品種中有數千種不同的品種 – 最常見的是卡本內蘇維翁（Cabernet Sauvignon）。

What is Wine?
Wine is an alcoholic beverage made with the fermented juice of grapes. Technically, wine can be made with any fruit (i.e. apples, cranberries, plums, etc) but most wines are made with wine grapes (which are different than table grapes). Speaking of differences, the difference between wine and beer is that beer is made from fermenting brewed grains. So very simply, wine is made from fruit and beer is made from grains.
Wine grapes are different than table grapes: they are smaller, sweeter and have lots of seeds. Most wines are made with a single species of grape that originated in Caucasus called Vitis vinifera. There are thousands of different varieties within the Vitis vinifera species–the most common is Cabernet Sauvignon.
The Origin of the term “Vintage”
Wine grapes take an entire season to ripen and thus, wine is produced just once a year. This is where the term vintage comes from: “Vint” stands for “Winemaking” and “age” implies the year it was made. So, when you see a vintage year listed on the label, that’s the year the grapes were picked and made into wine. The harvest season in the northern hemisphere (Europe, US) is from August–September and the harvest season in the southern hemisphere (Argentina, Australia) is from February–April.
Non-Vintage (NV) Wine
Occasionally, you’ll find a wine without a vintage listed on the label. Typically, this is a blend of several vintages together; and in the case of Champagne, it will be labeled with “NV” which stands for “Non-Vintage.”
A single-varietal wine is made primarily with one type of grape. It’s common to see these wines labeled by the name of that grape variety. For example, a bottle of Riesling is made with Riesling grapes. It’s useful to note that each country has different rules for how much of the variety should be included in order to be labeled as a varietal wine.
A wine blend is a wine made with a blend of several grape varieties. Blending is a traditional method of winemaking, and today there are several famous wine blends produced in classic winemaking regions. Just so you know, most wine blends are mixed together after the fermentation (and aging) is complete. When grapes are blended and fermented together it is called a field blend. A famous example of a field blend is Port wine.
