An abbreviation for Klosterneuburger Mostwaage, a measurement of must weight used in Austria. A more widespread equivalent, which is used in Germany, is the Oechsle scale. Elsewhere you are more likely to hear of Baumé and Brix. 1 KMW is equivalent to approximately 5 Oechsle. It is vital for the winemaker to determine the must weight in Germany and Austria because it determines the Prädikat category - Kabinett, Spätlese or Auslese - under which the wine will be labelled.
