Pressing (wine) red wine production the timing of when to press is one of the most important decisions in the wine making process since that will be the moment that maceration and phenolic extraction ceases. Some winemakers use the decreasing sugar level (such as brix measurement) scale and press once the wine has reached complete dryness. Often winemakers will use taste to determine if the wine has extracted enough tannins to produce a balanced wine and may press before complete dryness (such as at 3-8 brix). Though removing the skins by pressing often removes some solids that the wine yeast need to
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
