Classic Sauvignon Blanc aromas range from grass, nettles, blackcurrant leaf and asparagus to green apples and gooseberries, and to more esoteric notes such as cats' pee and gunflint. The latter is a sign of a wine from Pouilly-Fumé, where the struck flint aroma (known there as pierre à fusil) derives from the presence of high levels of chert in the local
limestone soils.
