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 ...
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 ...
Carbon dioxide gas dissolved in the water content of wine. It is a volatile acid that held in equilibrium with the dissolved carbon dioxide gas and can not be isolated in a pure form. Carbonic gas A natural by product of the fermentation process in which yeast cells convert sugar into nearly equal parts alcohol and carbonic gas. While a small ...
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.
Mead (/ m iː d /), also called hydromel, is an alcoholic drink made by fermenting honey with water, sometimes with various fruits, spices, grains, or hops. The alcoholic content of mead may range from as low as 3% ABV to more than 20%. The defining characteristic of mead is that the majority of the drink's fermentable sugar is derived from honey.
A 16th-century brewery Brewing is the production of beer by steeping a starch source (commonly cereal grains, the most popular of which is barley) in water and fermenting the resulting sweet liquid with yeast. It may be done in a brewery by a commercial brewer, at home by a homebrewer, or communally. Brewing has taken place since around the 6th millennium BC, and archaeological evidence ...
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 ...
