Must Weight: Measurement of the sugar content in grape must, or unfermented grape juice, which indicates the potential alcohol of the juice were all of the sugar to be converted to alcohol during fermentation. Like Brix, Baumé and Oechsle, must weight is more accurately a measurement of the must's density or specific gravity.

未发酵葡萄汁的重量：用于测量葡萄汁或未发酵葡萄汁的含糖量，显示出在发酵过程中葡萄汁中所有糖份转化成酒精的潜在酒精含量。像百利糖度，波美度和奥斯勒度一样，未发酵葡萄汁的重量更确切的说是未发酵葡萄汁的密度或比重的量度。
