Secondary fermentation is a process commonly associated with winemaking, [1] which entails a second period of fermentation in a different vessel than the one used to start the fermentation process. An example of this would be starting fermentation in a carboy or stainless steel tank and then moving it over to oak barrels. Rather than being a ...
Secondary fermentation Most commonly the term is used to refer to the continuation of fermentation in a second vessel – e.g. moving the wine from a stainless steel tank to an oak barrel. The Australian meaning of this term is malo lactic fermentation MLF, as distinct from primary fermentation, the conversion of sugar to alcohol. Skin contact
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.
Before fermentation, pectin-splitting enzymes and, for white wine, fining agents such as bentonite may be added to the must in order to promote the eventual agglomeration and settling of colloids. [1] Pectins are structural molecules in the cell walls of fruits which have the important function of 'gumming' plant cells together.
Pigeage is a French term for the management of acidity and secondary pressing of grapes in fermentation tanks. To make certain types of wine, grapes are put through a crusher and then poured into open fermentation tanks. Once fermentation begins, the grape skins are floated to the surface by carbon dioxide gases released in the fermentation ...
Mead is a drink widely considered to have been discovered likely among the first humans in Africa 20,000 - 40,000 thousand years ago [17] [18] [19] prior to the advent of both agriculture and ceramic pottery in the Neolithic, [20] due to the prevalence of naturally occurring fermentation and the distribution of eusocial honey-producing insects worldwide; [21] as a result, it is hard to ...
Secondary fermentation may refer to: Secondary fermentation (wine) - a second fermentation in wine-making; Secondary fermentation - a second fermentation in brewing beer
It is traditionally a form of mead, an alcoholic beverage produced by fermenting a solution of honey and water, although in modern times the honey is generally replaced with different kinds of sugar, mostly syrup, which makes it a sugar wine. [1] The drink also has a very low alcohol content due to limited fermentation.
