Riesling offers a wealth of highly aromatic and diverse styles of white wine. Riesling can vary from bone dry, all the way through to lusciously sweet Beerenauslese (BA) and Trockenbeerenauslese (TBA). Its ability to age and transmit the terroir of the vineyard without losing its individual character places it amongst the most noble and academic of grape varieties. Germany is seen as Riesling's Old World home with the greatest concentration in the Mosel Valley, however, plantings have steadily increased across the border in the region of Alsace, France. Most Alsation Rieslings tend to be on the drier side. Even though some Grand Crus contain more sugar, they are still very refreshing and appetizing, due to a high level of acidity.
