This is achieved by all of the above: arresting fermentation by chilling the wine, adding sulfur to the wine to stop fermentation, sterile filtration of the wine to filter out yeasts, adding sterile juice concentrate to a base wine fermented to completion In carbonic maceration, whole berries are sealed in a fermentor for 8-10 days under CO2.

For example, the number of fruit clusters that will develop on a vine in the spring is determined by: the number of buds left on the vine after pruning a sparkling wine bottle labeled as fermented in this bottle has been made following the traditional method during production of a sparkling wine, the term cure refers to the base wine before addition of sugar and the secondary fermentation optimal growing conditions for grapes worldwide include regions with a temperate climate which if the following are important white grape cultivars used in winemaking chardonnay and semillon there is some evidence that, when consumed in moderation, the antioxidant effects of wine may be helpful in delaying or preventing: atherosclerosis cap management in fermentation practice refers to removing the debris that floats to the top of the fermentation tank a carbonated wine is noticeably fizzy due to artificial addition of CO2 during production the bacterium acetobacter aceti is responsible primarily for what biochemical reaction conversion of ethanol to acetic acid for individuals are 21 or over, a person considered driving under the influence if their blood alcohol level is .08 fetal alcohol syndrome is a serious syndrome that can include fetal deformities and mental retardation the major sources of wine flavor include which of the following all of the above, the aging process used, the fermentation process, the grapes that are used, the processing steps employed the term 'Brut' on a bottle of sparkling wine refers to the sweetness of the wine wine alcohol content after fermentation is about 55% of the initial must sugar content.
