Grapes being pressed to create must. Must (from the Latin vinum mustum; lit. ' young wine ') is freshly crushed fruit juice (usually grape juice) that contains the skins, seeds, and stems of the fruit. The solid portion of the must is called pomace and typically makes up 7–23% of the total weight of the must. Making must is the first step in ...
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 grape reaction product (GRP, GRP1 or 2-S-glutathionyl caftaric acid [1]) is a phenolic compound explaining the disappearance of caftaric acid from grape must during processing. [2] It is also found in aged red wines. [3] Its enzymatic production by polyphenol oxidase is important in limiting the browning of musts, [4] especially in white ...
Malolactic fermentation can aid in making a wine "microbiologically stable" in that the lactic acid bacteria consume many of the leftover nutrients that other spoilage microbes could use to develop wine faults. However, it can also make the wine slightly "unstable" due to the rise in pH, especially if the wine already was at the high end of ...

To make crack grapes, simply melt a few Jolly Rancher candies in the microwave in a silicone baking cup, then dip fruit stabbed onto wooden skewers into the mixture to lightly coat.
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 ...
