In detail, the olfactory analysis can be divided into two parts, the first and second nose. At the first nose, when leaving the wine immobile, the most vivid aromas appear. At the second nose, when one gives the glass a turn of the wrist, the wine exhales its hidden scents. The first nose phase reveals the development of the bouquet, its intensity, its persistency, the maturity of the fruit, the use of wood, and a general criterion of quality. The second nose phase defines the families of aromas and each of its perfumes.
