Harvest
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 and its timing is determined by sugar, acid and flavor balance. Grapes meant for high acid white wines are often picked earlier, while fuller bodied, high sugar red wine grapes are picked later.

Lees
Lees are the dead yeast cells, grape seeds and skins left over in the fermentation tank after fermentation. There are two types of lees; gross lees and fine lees.
Oak
Oak imparts flavor, aroma and texture into wines through fermentation in oak barrels. These barrels act as gentle, breathable vessels that add complex notes and improve the wine's overall structure and mouthfeel.
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.
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.
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).
Hybrid
Hybrid varieties are created by crossing two or more different grapevine species to get a final product that offers resistance to cold, diseases and humidity, making them ideal for tough climates.
Lactic Acid
Lactic acid is a soft organic acid produced during malolactic fermentation of wines. It smoothens the wine's total acidity, increases pH and adds creamy, buttery or velvety textures and flavors.
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.
