Term for the positive taste impression of a wine in the context of a wine address. This is attributed to dry wines that have grown on soils with a flint content and are characterised by great purity. The French white wines Chablis, Pouilly-Fumé and Sancerre, as well as the Italian Vernaccia di San Gimignano are often mentioned in this context. This flavour is due to sulphurous soaps. Responsible for the smoky aroma are certain thiols (mercaptans - benzyl mercaptan), which are produced by chemical reactions after fermentation. The flint aroma is assigned to the group of mineral tones.
The wein.plus encyclopaedia is a comprehensive, well-researched reference work. Available anytime and anywhere, it has become an indispensable part of teaching, used by students and myself alike. Highly recommended!Dominik Trick
