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.

Clarification
Wine clarification is a process winemakers use to remove suspended solids, such as dead yeast (lees), grape skins, pulp and proteins.
Aging
Aging is a post fermentation process where wine rests in barrels (mainly oak) or bottles to undergo chemical changes that improves stability, develops complex flavors and clarifies the liquid.
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.
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.
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).
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.
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.
