Winemaking taste of the wine. Brix (°Bx) is one measure of the soluble solids in the grape juice and represents not only the sugars but also includes many other soluble substances such as salts, acids and tannins, sometimes called total dissolved solids (TDS). Because sugar is the dominant compound in grape juice, these units are effectively a measure of sugar level. The level of sugar in the grapes determines the final alcohol content of the wine as well as indirect index of grape maturity. °Bx is measured in grams per hundred grams of solution, so 20 °Bx means that 100 grams
Content (measure theory) Content (measure theory) In mathematics, a content is a set function like a measure but a content need not be countably additive, but must only be finitely additive. A content is a real function formula_1 defined on a field of sets formula_2 such that An example of a content is a measure, which is a "σ"-additive "content" defined on a "σ"-field. Every (real-valued) measure is a content, but not vice versa. Contents give a good notion of integrating bounded functions on a space but can behave badly when integrating unbounded functions, while measures give a good notion of integrating unbounded
