A refractometer is a small, handheld tool that uses a prism to measure the amount of sugar in a grape. The prism shows us how the liquid affects the bending of light. Different substances bend light in varying amounts. Today, we’re checking our Noiret grapes.
Vineyard owner Randy Rice explains how he uses a refractometer to measure the brix (sugar levels) in grapes. A refractometer is an instrument, usually hand-held, that measures dissolved sugar in a small juice sample in the field. Refractometers make it possible to determine ideal harvesting times of grapes so that the product arrives in an ideal state to consumers or for subsequent processing steps such as vinification.
Brix, determined at harvest time, is a measure of soluble solids content in grapes, mostly as sucrose, determined by the use of a refractometer, a hand-held instrument that measures dissolved sugar in a small juice sample in the field.To use a refractometer, you simply squeeze a drop of juice onto a glass plate and look through an eyepiece. The refractometer will show you a scale with numbers indicating the brix level of the juice sample. There are two ways to test for Brix in your grape juice and/or must. Prior to the addition of yeast and fermentation, one may use a hand refractometer to measure the sugar content (Brix) of the grapes. First the sampling method must be discussed.Brix is measured using one of two instruments — a refractometer (pictured above) if measuring grape juice prior to fermentation, or a hydrometer (pictured to the right) if measuring juice during or post fermentation.

Wine refractometers act to measure the Brix present in the grapes, thus allowing you to determine if they are ready to be harvested or if they need to remain on a vine for a longer period of time. Wine refractometers work by using light to measure the density of water-soluble compounds in a sample.Learn how to measure the sugar levels in wine grapes using a refractometer to determine when to pick red wine grapes.This video discusses the use of a refractometer to determine grape ripeness, and total sugar content.
