Emerald Riesling

Emerald Riesling is a white grape variety. It is a new breed between Muscadelle and Riesling. The crossing was made in 1935 by Harold Olmo at the University of California at Davis. The launch of the grape was in 1948. Currently, only small populations in California are planted with the variety Emerald Riesling ( in 2008 about 235 acres = 94 acres ). In addition, stocks in Australia, Israel, New Zealand, Slovenia, Spain, South Africa, Hungary and Cyprus are known. Emerald Riesling produces wines with good acidity levels, which are used for blends.

Ampelographic varietal characteristics

In the ampelography the habit is described as follows:

• The shoot tip is open. She is hairy spinnwebig. The young leaves are almost glabrous.
• The large leaves are five-lobed and barely sinuate. The petiole is U-shaped open. The blade is serrated blunt. The teeth are medium in size compared to other varieties.
• The cone - shaped to cylindrical cluster is large, shouldered and mitteldichtbeerig. The roundish berries are medium in size and of a light yellow color.

The strong growing variety is particularly suited to the warm coastal areas of California. It ripens about 20 - 25 days after Chasselas. After the harvest, the grapes must be processed very quickly, as they tend to oxidation.
