Some wines lack density, complexity and fruit charm despite noticeable alcoholic strength; the tannins often turn out relatively brittle and drying and the ethereal aromas so typical of Nebbiolo sometimes turn camphor-like green. While the best wines gain depth in the air and become smoother and finer, the less good examples hardly develop positively or even in the opposite direction after opening - they become more brittle and even greener.
