    Study Notes

    Winemaking Process

    • Yeast consumes sugar in juice to produce alcohol, carbon dioxide, and other byproducts during fermentation.
    • Fermentation can be controlled by temperature, oxygen, and nutrient levels.
    • Fermentation can be stopped or restarted by cooling, filtering, or adding sulfur dioxide.
    • Fermentation takes place in various vessels, such as stainless steel tanks, oak barrels, or concrete eggs.

    Aging and Maturation

    • Wine is stored and aged for a period to improve its quality and complexity.
    • Aging and maturation can be done in different vessels, such as oak barrels, stainless steel tanks, or bottles.
    • Aging and maturation may involve processes like malolactic fermentation, racking, fining, filtering, or blending.
    • Aging and maturation is an optional step, as some wines are meant to be consumed young, while others benefit from aging.

    Bottling and Labeling

    • Wine is transferred into bottles and sealed with a closure, such as a cork, screw cap, or synthetic stopper.
    • Bottling and labeling may involve adding additives like sulfur dioxide, sugar, or acid to adjust the wine's stability and balance.

    Bordeaux Blends

    • A typical Libournais Bordeaux blend consists of Merlot, Cabernet Franc, Cabernet Sauvignon, and Cru Classifications of Bordeaux.
