Assemblage
Assemblage
Assemblage, or blending is a critical and artistic French winemaking technique of combining different base wines which vary by grape variety, vintage or vineyard parcel, to create a balanced, complex final wine (cuvée). It enhances quality by balancing strengths and weaknesses, such as combining wines high in acidity with low acid ones, fundamental for achieving consistency in Champagne and Bordeaux.

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.
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.
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, while higher yields produce lighter and less concentrated wines.
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).
Lees
Lees are the dead yeast cells, grape seeds and skins left over in the fermentation tank after fermentation. There are two types of lees; gross lees and fine lees.
Malic Acid
Malic acid is a naturally occuring organic acid in wine grapes, primarily found in unripe or cool climate berries. It gives a sharp acidity, tartness and freshness to 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.
Irrigation
Irrigation is the artificial application of water to vineyards to provide the necessary 25-35 inches of annual water in dry climates.
