Irrigation
Irrigation
Irrigation is the artificial application of water to vineyards to provide the necessary 25-35 inches of annual water in dry climates. It is used to manage vine health, growth and grape quality while preventing drought stress and improving yields. Drip irrigation is the most popular method for providing precise water directly to the roots, while wine growers in some regions carry out flood or surface irrigation.

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.
Maceration
Maceration in wine is the process of soaking crushed grape skins, seeds and stems in the juice (must) to extract color, tannins and aroma compounds.
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).
Fermentation
Fermentation is a natural biochemichal process where yeast consumes the natural sugars in grape juice and converts them into alcohol, carbon dioxide and heat. At the end of fermentation, grape juice is converted into wine.
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.
Sulfites
Sulfites (sulfur dioxide or SO₂) are chemical compounds naturally produced by yeast during wine fermentation. They act as preservatives, also commonly added by winemakers to prevent bacterial growth, spoilage and oxidation.
Clarification
Wine clarification is a process winemakers use to remove suspended solids, such as dead yeast (lees), grape skins, pulp and proteins.
Yeast
Yeast in wine is a microscopic, single celled fungus, typically Saccharomyces cerevisiae, which triggers fermentation by transforming the sugars in must into ethanol and carbon dioxide. Yeasts are essential for converting grape juice into wine and they determine its final alcohol content, aroma and flavor profile.
