In the German-speaking world, a colloquial term (also called Stinkerchen) is used to describe the smell and taste of a wine in the context of a wine-tasting, which is also described as animalistic or earthy. The minimizing form "Stinkerl" ("small, slight stinker") is to be understood rather positively. However, what exactly is meant by this is interpreted differently or there are no objective criteria (e.g. certain aromas) that allow a clear identification. It is an impression that is foreign to wine and results from chemical compounds. The cause can be, among other things, the type of alcohol geosmin.
