Hybrid
Hybrid
Hybrid grape varieties are the product of crossing two or more different grapevine species, typically blending European varieties (e.g Chardonnay) with native species. These grapes offer high resistance to cold, diseases and humidity, making them ideal for tough climates. Hybrids often have thinner skins and lower tannins and they may feature unique flavor profiles different from traditional European wines. Common examples include Vidal Blanc, Marquette and Baco Noir.

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.
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.
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.
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.
TCA
TCA stands for 2,4,6-trichloroanisole, a chemical compound that causes "cork taint". It forms when natural fungi in corks or wooden barrels interact with chlorine in cleaning products, resulting in musty, moldy or wet cardboard aromas in wines.
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).
Clarification
Wine clarification is a process winemakers use to remove suspended solids, such as dead yeast (lees), grape skins, pulp and proteins.
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.
