Description for especially the smell but also the taste of a wine in the context of a wine address. The aromatic substance megastigmatrienone is responsible for this. Especially wines from the varieties Chardonnay, Merlot, Sauvignon Blanc and Syrah have this unique dry-sweetish note of tobacco, which is typical for cold cigars. But this is also typical for wines that have undergone barrique ageing. A taste of roasted tobacco is caused by Sotolon.
