Some grapes are easier to recognize than others. Sauvignon Blanc is easy but not the easiest. That distinction goes to Muscat and Gewürztraminer. But still, in a blind tasting you have a fair chance of identifying the Sauvignon Blanc.
However, Sauvignon Blanc, like most other grapes, is influenced by their environment, be it the soil, the climate or the winegrower. In a small area like the Pouilly Fumé appellation in the Upper Loire there are a number of different soil types. You have different kinds of limestone present in different proportions, you have flint stone, you have clay etc.
All this is reflected in the wine and although sometimes, to be honest, the differences are very subtle, in a well-made, good quality wine you feel them if you make an effort.
