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.

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.
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.
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.
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.
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.
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.
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.
