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.
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
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 prior to the advent of both agriculture and ceramic pottery in the Neolithic, [17] due to the prevalence of naturally occurring fermentation and the distribution of eusocial honey-producing insects worldwide; [18] as a result, it is hard to pinpoint the exact historical origin of mead given the possibility of multiple discovery or ...
The duration of fermentation affects the quality; longer fermentation preserves the wine's aromas better and gives finer and more durable bubbles. [ 18 ] This production method is widely used in the U.S., in Italy, especially in the Asti province , and in Prosecco wines, and in Germany to produce variants of Sekt such as Henkell Trocken.
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.
This secondary fermentation process is often utilized by more advanced home brewers to enhance flavor. While not required, it is generally practiced by home brewers who wish to age or clarify their beer by removing it from the sediment left behind by primary fermentation, often through the addition of isinglass, colloidal silicon dioxide, or ...
