Designation (also base wine) for a processing wine that is not suitable for consumption for the production of wine spirit or brandy. Acidic grape varieties such as Airén, Baco Blanc, Colombard, Folignan, Folle Blanche, Graisse, Jurançon Blanc, Mauzac Blanc, Mauzac Rose, Meslier Saint-François, Montils, Select and Ugni Blanc (Trebbiano Toscano) are suitable for this purpose. A wine distillate of up to 86% vol. is added to a fully fermented wine with minimal residual sugar, resulting in an alcohol content of 18 to a maximum permitted 22% vol. This is then used for further distillation.
In the past, you needed a wealth of encyclopaedias and specialist literature to keep up to date in your vinophile professional life. Today, Wine lexicon from wein.plus is one of my best helpers and can rightly be called the "bible of wine knowledge".
