Sparkling wine the production of still wine with some noted divergence. At the vineyard, grapes are harvested early when there is still high acid levels. In areas like Australia, winemakers aim to harvest the grapes at 17 to 20° brix. Unlike still wine production, high sugar levels are not ideal and grapes destined for sparkling wine production may be harvested at higher yields. Care is taken to avoid tannins and other phenolic compounds with many premium producers still choosing to harvest by hand rather than risk mechanical harvesting which may split the berries and encourage maceration between the skins and juice.

Content (measure theory) any compact "C", λ("C") is the inf of λ("D") for compact sets "D" containing "C" in their interiors. 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
