Dosage
Dosage
Dosage is the final step in producing traditional sparkling wine (such as Champagne). A small amount of wine and sugar, known as liqueur d’expédition is added to the wine after sediment is removed (disgorgement), just before corking. The “dosage” balances the high acidity of the sparkling wine, smoothens flavors and determines the final sweetness levels.

Racking
Racking refers to the process of transferring wine from one tank or barrel to another using gravity rather than a pump to separate clear liquid from sediment.
Malic Acid
Malic acid is a naturally occuring organic acid in wine grapes, primarily found in unripe or cool climate berries. It gives a sharp acidity, tartness and freshness to wine.
Anthocyanins
Anthocyanins are natural polyphenol pigments located in the red grape skins, responsible for the red, purple and blue colors in young red wines. They determine the wine's hue, shifting from vibrant red to brownish orange as they age.
Crush
The Crush refers to the period in late summer or fall when harvested grapes are mechanically broken to rupture their skins and release the juice, initiating the winemaking process.
Assemblage
Assemblage is the French term for the process where winemakers combine different base wines that vary by grape variety, vintage or vineyard parcel, to create a balanced and complex final wine.
Must
Grape must is the freshly pressed, unfermented grape juice which contains the fruit's skins, seeds and sometimes stems (collectively referred to as pomace).
Harvest
The harvest marks the end of the vine growing cycle, typically occuring between August and October in the Northern hemisphere. It is the stage where ripe grapes are picked from the vineyard to begin winemaking.
Oxidation
Oxidation is a chemical reaction that occurs when oxygen in the air comes in contact with the alcohol in wine, converting ethanol into acetaldehyde, then acetic acid. It causes wines to lose their vibrant colors and reduces fresh fruit aromas.
