What device measures sugar content?

refractometer
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.
