(Germany) A scale of must weight based on specific gravity. It is vital to assess the must weight in Germany as it determines the Prädikat classification. An Oechsle unit is equal to one unit of specific gravity above 1000. For example, the must of a Mosel with specific gravity of 1090 has an Oechsle of 90 and therefore qualifies as an Auslese. Other measures of must weight include Baumé, Brix and KMW. My article on must weight in my Sweet Wine series gives more information.
