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.
The liqueur d'expédition is a mixture of the base wine and sucrose, plus 0.02 to 0.03 grams of sulfur dioxide as a preservative. Some maisons de Champagne (Champagne brands) claim to have secret recipes for this, adding ingredients such as old Champagne wine and candi sugar.
Grapes being trodden to extract the juice and made into wine in storage jars. Tomb of Nakht, 18th dynasty, Thebes, Ancient Egypt. Sourdough starter. In food processing, fermentation is the conversion of carbohydrates to alcohol or organic acids using microorganisms—yeasts or bacteria—without an oxidizing agent being used in the reaction.
Melt butter, stir in flour; while stirring gradually, pour the wine into the light roux, add salt and lemon zest, bring to a boil, and stir vigorously, remove from heat, and let cool slightly ...
Mirin (味醂 or みりん, Japanese:) is a type of rice wine and a common ingredient in Japanese cooking. It is similar to sake but with a lower alcohol content and higher sugar content. [1] The sugar content is a complex carbohydrate that forms naturally during the fermentation process; no sugars are added. The alcohol content is further ...
In a second experiment, Pasteur used the same flasks and sugar-yeast mixture, but left it idle in 'swan-neck' flasks instead of introducing any extraneous matter. Some flasks were kept open to the common air as the control group, and these exhibited mold and microbial growths within a day or two.
A liqueur de tirage (sugar) is then added to the wine and bottled. A second fermentation then occurs in the bottle from yeast and the sugar from the liqueur de tirage. The wine is then dégorgé or disgorged and a liqueur de dosage or mix (liquor more or less sweet depending on the desired final product: brut, demi-sec, or doux).
Cato wrote extensively on the medical uses of wine, including a recipe for a laxative: wine made from grapevines treated with a mixture of ashes, manure and hellebore. He recommended that the flowers of certain plants, e.g. juniper and myrtle, be soaked in wine to help with snakebites and gout.
