General term for the dry, earthy smell or taste of a wine in the context of a wine address. This is defined more precisely by the aroma spectrum of concrete, soil, potato, fungus and mould. If it is less pronounced, this is understood as positive and is the characteristic (goût de terroir) of certain French red wines (see Stinkerl).
The reason for this is the type of alcohol Geosmin produced by soil bacteria. If it is more pronounced, this indicates various wine faults such as geranium tones, cork tastes or horse sweat. Related terms are musty, musty and mouldy, which also describe wine faults.
