Riesling is a white grape variety which originated in the Rhine region. Riesling is an aromatic grape variety displaying flowery, almost perfumed, aromas as well as high acidity. It is used to make dry, semi-sweet, sweet, and sparkling white wines. Riesling wines are usually varietally pure and are seldom oaked.
In cool climates tend to exhibit apple and tree fruit notes with noticeable levels of acidity that are sometimes balanced with residual sugar. A late-ripening variety that can develop more citrus and peach notes is grown in warmer climates. In Australia, Riesling is often noted for a characteristic lime note that tends to emerge in examples from the Clare Valley and Eden Valley in South Australia. Riesling's naturally high acidity and pronounced fruit flavors give wines made from the grape exceptional aging potential, with well-made examples from favorable vintages often developing smokey, honey notes, and aged German Rieslings, in particular, taking on a "petrol" character.
