German wines are primarily known for their high-quality white varieties, particularly those made from the Riesling grape. The country’s cool climate allows for a long growing season, which helps develop the grapes' natural acidity and aromatic qualities. German wines are often categorized by their sweetness levels, ranging from dry to sweet, with designations like Trocken (dry) and Eiswein (ice wine) indicating the style. Germany is divided into 13 wine regions, known as Anbaugebiete, with the most famous being the Mosel, Rheingau, and Pfalz. These regions are characterized by their unique terroirs, which influence the flavor profiles of the wines. The country also produces notable red wines, primarily from the Spätburgunder (Pinot Noir) grape, showcasing a diverse range of wine styles.
