Yield
Yield
The yield signifies the amount of grapes or wine produced from a specific vineyard area, commonly measured in tons per acre in the US, or hectoliters per hectare in Europe. Lower yields are associated with better quality, as the vine focuses its energy and nutrients into fewer grapes, thus giving concentrated and more intense flavor profiles, Higher yields on the other hand, produce lighter and less concentrated wines. Vine age, grape variety, soil type and vineyard management all influence the yield.

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.
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.
Dosage
Dosage is the final step in producing traditional sparkling wine (such as Champagne) where a small amount of wine and sugar, known as liqueur d'expédition is added to the wine after sediment is removed (disgorgement), just before corking.
Viticulture
Viticulture is the branch of science that deals with the study, cultivation and harvesting of grapes specifically for winemaking. It includes all vineyard activities, such as planting, pruning, training vines, soil irrigation and pest control.
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.
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.
Irrigation
Irrigation is the artificial application of water to vineyards to provide the necessary 25-35 inches of annual water in dry climates.
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.
