Mosel is most famous for its vertiginous slate vineyards, home to some of the world`s finest Riesling. It is a northerly region and the wines are no strangers to high acidity, so a touch or more of residual sugar goes a long way in balancing this. Wines can be very long lived, but I find they are drinkable from the off and don`t seem to close down. (CW 23/01/12)
