The natural occurrence of fermentation means it was probably first observed long ago by humans. [3] The earliest uses of the word "fermentation" in relation to winemaking was in reference to the apparent "boiling" within the must that came from the anaerobic reaction of the yeast to the sugars in the grape juice and the release of carbon dioxide.
Carbonic maceration is a winemaking technique, often associated with the French wine region of Beaujolais, in which whole grapes are fermented in a carbon dioxide rich environment before crushing. Conventional alcoholic fermentation involves crushing the grapes to free the juice and pulp from the skin with yeast serving to convert sugar into ...
Maceration is the chief means of producing flavored alcoholic beverages, such as cordials, liqueurs, and Geister. [ citation needed ] Maceration of byproducts from food processing plants and other organic byproducts such as cooking oil, stubble, wood chips or manure can involve the use of a chopper pump to create a slurry which can be used to ...
Spanish winemaking term describing a wine that is macerated with double the normal ratio of grape skins to juice. This is achieved by the winemaker bleeding off and disposing of extra juice in order to increase the ratio of grape skin and concentration of phenolic compounds. Doppelstück A German oak barrel that holds 635 gallons (2,400 liters).
Maceration continues during the fermentation period, and can last well past the point when the yeast has converted all sugars into alcohol. The process itself is a slow one with compounds such as the anthocyanins needing to pass through the cell membrane of the skins to come into contact with the wine.
Madeira blueberry or Uva-de-serra [1] (Vaccinium padifolium) is very common at elevations between 800 and 1,700 metres (2,600 and 5,600 ft). It grows mainly in crevices and exposed slopes and mountain plains.
Orange wine (a.k.a. skin-contact white wine) is wine made with maceration in the manner of rosé or red wine production, but using white wine grape varieties instead of red. To start primary fermentation, yeast may be added to the must for red wine, or may occur naturally as ambient yeast on the grapes (or in the air).
Blueberry jam is made from blueberries, sugar, water, and fruit pectin. Blueberry sauce is a sweet sauce prepared using blueberries as a primary ingredient. Blueberry wine is made from the flesh and skin of the berries, which is fermented and then matured; usually, the lowbush variety is used.
