A wine that starts out as a lighter bodied and perhaps weaker flavor that is blended with a stronger, more robust wine. Sparging A process of adding carbonic gas to a wine just before bottling in order to add some slight effervescence to the wine. Spinning cone column Used to reduce the amount of alcohol in a wine. Stabilization
Wine press – device used to extract juice from crushed grapes during wine making. History of the wine press; Must – freshly pressed fruit juice (usually grape juice) that contains the skins, seeds, and stems of the fruit. Pomace – solid remains of grapes, olives, or other fruit after pressing for juice or oil. It contains the skins, pulp ...
The biochemical process of fermentation itself creates a lot of residual heat which can take the must out of the ideal temperature range for the wine. Typically, white wine is fermented between 18–20 °C (64–68 °F) though a wine maker may choose to use a higher temperature to bring out some of the complexity of the wine.
The space between the wine and the top of a wine bottle. As a wine ages, the space of ullage will increase as the wine gradually evaporates and seeps through the cork. The winemaking term of "ullage" refers to the practice of topping off a barrel with extra wine to prevent oxidation. Unctuous A wine that has layers of soft, concentrated ...
Wine grapes from the Guadalupe Valley in Ensenada, Baja California, Mexico. Winemaking, wine-making, or vinification is the production of wine, starting with the selection of the fruit, its fermentation into alcohol, and the bottling of the finished liquid. The history of wine-making stretches over millennia.
Grape-treading or grape-stomping is part of the method of maceration used in traditional wine-making. [ 1 ] [ 2 ] [ 3 ] Rather than being crushed in a wine press or by another mechanized method, grapes are repeatedly trampled in vats by barefoot participants to release their juices and begin fermentation .
Chaptalization is the process of adding sugar to unfermented grape must in order to increase the alcohol content after fermentation. The technique is named after its developer, the French chemist Jean-Antoine-Claude Chaptal. [1] This process is not intended to make the wine sweeter, but rather to provide more sugar for the yeast to ferment into ...
The wine can then be siphoned or "racked" off the compact solids into a new container. [3] But this process may take many months, or even years, as well as several rackings, in order to produce a perfectly clear wine. Producers can accelerate the process by using fining agents, filtration and/or flotation. [1]
