Germany is the northernmost winegrowing country, with large climatic differences between regions. There are 13 winegrowing areas in the south-eastern part of Germany. They extend along the Rhine and its tributaries from Freiburg in the south to Cologne in the north. The predominant grape variety is Rhine Riesling. German Riesling usually contains a low level of alcohol, has a pleasant acidity and smells of fruit, most often of green apple, apricot or peach, sometimes even smoke.
