Degrees Brix (symbol °Bx)'s a measurement of the dissolved sugar-to-water mass ratio of a liquid. It's measured with a saccharimeter that measures specific gravity of a liquid or more easily with a refractometer. A 25 °Bx solution's 25% (s/w), with 25 grams of sugar per 100 grams of solution. Or, to put it another way, there're 25 grams of sucrose sugar and 75 grams of water in the 100 grams of solution.
