Which of the following is considered a characteristic feature of Riesling wines from Alsace?

Riesling wines from Alsace are known for their high acidity and distinct floral notes, which are key characteristics of this varietal. The high acidity helps to ensure that the wines have a refreshing quality, making them versatile for food pairings and enhancing their aging potential. Additionally, the floral aromas, often reminiscent of jasmine or orange blossom, contribute to the aromatic complexity of Alsace Rieslings, making them particularly appealing to wine enthusiasts.

This combination of high acidity and floral notes typifies the style of Riesling produced in Alsace, distinguishing it from other regions where the grape may be made in different styles. Other characteristics associated with this region can include fruitiness, minerality, and sometimes varying degrees of sweetness, but the high acidity and floral aspect remain central to its identity.
