Sediment
Sediment
The term “sediment” signifies the natural, organic by products of the winemaking and aging process. It is made up of grape solids (skins, seeds, pulp), dead yeast cells (lees) and tartarate crystals (wine diamonds). It is harmless and safe to consume, but it may have an unpleasant texture or taste slightly bitter. Sediment is more common in aged red wines, showing minimal filtering and high quality, traditional production.

Clarification
Wine clarification is a process winemakers use to remove suspended solids, such as dead yeast (lees), grape skins, pulp and proteins.
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.
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.
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.
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.
Saccharomyces Cerevisiae
Saccharomyces Cerevisiae is the major yeast species involved in wine fermentation. Also known as "wine yeast" or "baker's yeast", it converts the sugar in grape juice to ethanol and carbon dioxide, creating wine.
Irrigation
Irrigation is the artificial application of water to vineyards to provide the necessary 25-35 inches of annual water in dry climates.
