About Riesling Riesling is a hardy vine that is well-suited for cool-climate wine regions. It is perhaps most associated with the white wines of Germany, where it produces wines that range from dry to sweet. On the vine, ripe Riesling grapes are deep golden yellow in color, and the resulting wine can range from pale yellow to richly golden in the glass. Riesling is most known for its sharp acidity, which lends ample structure and lift to the wine, even in the sweetest of offerings. This bold acidity contributes the ageability of these wines, some of which can last for decades.
