It’s about the quality rather than quantity
Rheingau is not one of the largest wine regions in Germany, but it sure is quite important and well regarded. With just over 3000 hectares of dedicated vineyard, the quantity of wine produced here is miniscule compared to regions like Rheinhessen and Pfalz. The region is located on the west of Frankfurt and majority of its vineyards are in south facing slopes overlooking the Rhine. The major grape in the region is Riesling, accounting for about 80% of the total vineyards. Unsurprisingly, the classic wine of Rheingau is a dry Riesling with pronounced minerality and with more body than its counterpart from Mosel. Another important wine in Rheingau is a sweet wine made using botryized Riesling.
