Like most winery operations, the main goal of proper cleaning and sanitation is to promote wine quality, and to keep quality consistently high. Consistent quality, in turn, contributes to the winery’s positive reputation and promotes sales. Improper sanitation can lead to unwanted sensory characteristics from spoilage yeast and spoilage bacteria, as well as unwanted fermentations, which may cause fizziness, haze, pushing corks, and even shattered bottles.
