Term for grapes of those grape varieties that are primarily used to make wine. It is derived from the term Keltern (for pressing). Within the European Union, cultivation is bound to the quantities of vineyards for wine production specified in the respective vineyard register. Only grape varieties that have been classified as such by the wine-growing countries may be planted for wine production in the specified quantities (see Quality wine grape varieties). The picture shows the six most common wine grape varieties worldwide: Cabernet Sauvignon, Merlot, Tempranillo, Airén, Chardonnay and Syrah.
The glossary is a monumental achievement and one of the most important contributions to wine knowledge. Of all the encyclopaedias I use on the subject of wine, it is by far the most important. That was the case ten years ago and it hasn't changed since.
