Amphora
Amphora
Amphora refers to 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 and are popular in natural winemaking for producing pure and expressive orange wines.

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.
Irrigation
Irrigation is the artificial application of water to vineyards to provide the necessary 25-35 inches of annual water in dry climates.
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).
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.
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.
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.
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.
pH
The pH of wine is the measure of its total acidity (hydrogen ion concentration), typically ranging from 2.9 to 4.0 in most wines.
