I’m pretty sure he’s using a Brix meter, which provides a measurement in degrees of brix. Essentially lets the winemaker know how much sugar is in the grapes
Changes in Brix does not slways correlate exactly with sugar content as other soluable solids are included in reading. Things like carotinoids etc. A little something to pay attention too when comparing varieties.

Slight clarification
A brix meter measures soluable solids in the juice. A major portion of which is sugar.
