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.

Viticulture
Viticulture is the branch of science that deals with the study, cultivation and harvesting of grapes specifically for winemaking. It includes all vineyard activities, such as planting, pruning, training vines, soil irrigation and pest control.
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).
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.
Clarification
Wine clarification is a process winemakers use to remove suspended solids, such as dead yeast (lees), grape skins, pulp and proteins.
Pruning
Pruning is the essential act of cutting back dormant grapevines to remove old wood and limit the number of future buds. It is important for managing vineyard health, controlling grape yield and improving fruit quality.
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.
Amphora
Amphora is a traditional clay or terracotta vessel used for fermenting, aging and storing wine. These vessels are neutral and porous, allowing micro oxygenation without adding oak flavors.
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.
