Refractometer
A refractometer measures sugar ratio in the grape juice by refracting (bending) light. The higher the sugar content, the more refraction.
Residual sugar
Residual sugar is the sugar left after the wine has finished fermenting.
Refractometer
An instrument to estimate the sugar content of grape juice by measuring the bending of light passing through it.
Region
A geographical area less specific than a district, but more specific than a country.
Refractometer
handheld instrument used by vineyard manager to measure percentage of sugar in grape and thus make decision as to when to harvest ...
Refractometer:A handheld instrument that gauges grapes' ripeness by measuring the ratio of sugar and other solids in the grape juice. Used extensively during harvest by grapegrowers.
When a refractometer is used, it is correct to report the result as "refractometric dried substance" (RDS). One might speak of a liquid as being 20 °Bx RDS.
Winemakers measure the must weight, generally with a refractometer, to calculate the potential alcohol. The three international scales used in this analysis are "baumé", "brix", and "oechsle".
Brix (as Sucrose, for which most refractometers are calibrated), and multiply by 0.00425 and then add 0.9988 to the resulting number. This will give a close approximation to the equivalent figure for the S.G of Sucrose at 20 deg. C.
