Oak
Oak
Oak imparts flavor, aroma and texture into wines through fermentation in oak barrels. These barrels act as gentle, breathable vessels that add complex notes of vanilla, spice and toast while improving the wine’s overall structure and mouthfeel. There are two types of oak: French oak has a tighter grain and it contributes subtle spice and silky flavors to wine. American oak is bolder, known for its higher vanilla and coconut compounds.

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.
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.
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.
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.
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).
Hybrid
Hybrid varieties are created by crossing two or more different grapevine species to get a final product that offers resistance to cold, diseases and humidity, making them ideal for tough climates.
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.
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.
