The term 'CELLAR PROCESS' refers to the process of AGING wine in a cellar. This is done to allow the wine to mature and develop its flavor and aroma. The process involves storing the wine in a cool, dark place for a period of time, usually several months or years. During this time, the wine undergoes chemical changes that give it its unique characteristics. AGING also helps to reduce the acidity of the wine, making it smoother and more enjoyable to drink.
