Aroma and Bouquet
When it comes to the “nose” of a wine, there are really two aspects: aroma and bouquet. The “aroma” is the smell of the grapes themselves, sometimes called the “fruit”. Every variety has characteristic smells and the more tasting you do the more you build up that library of characteristic, varietal smells in your brain that can be retrieved when you sniff a wine. The “bouquet”, on the other hand, is different. It may include the aroma (smell of the grapes), but is complicated by all that is done to the wine when processed and new smells evolve. This could include oak contact and other procedures that can add or alter aromatics to the nose. Most tasters don’t usually break the nose down to this degree, but it’s important to understand.
