What distinguishes German Rieslings from those produced in other regions?

The purity of fruit, lively acidity, and distinct minerality of German Rieslings are attributed to the regions' diverse terroirs and cool climate. The grading system, that classify wines by ripeness, is what makes German Rieslings so unique as it gives the consumer clear understanding of sweetness levels. Also, the traditional winemaking practices like the fermentation in large oak barrels or stainless steel tanks play an important role in giving the German Rieslings the unique flavor profiles.
