Joh. Jos. Prüm estate (often just called “J.J.”) is situated in the Middle Mosel valley, around the 50th latitude, i.e. in one of the most northern wine-growing areas of the world. The consequence is an extremely long vegetation period until November, sometimes even December, with relatively cool climate conditions which give the Riesling grape time enough to develop all those typical fruity, floral and herbal aromas and flavours, keep a relatively high acidity and absorb the fine minerals from the slate soils. In order to balance this acidity, the natural grape sugar is typically not totally fermented into alcohol but there is a certain amount of residual sugar kept. This method of vinification together with the cool climate conditions (with the consequence of a lower natural sugar content) result also in a rather low alcohol content.
