More About Carboy - Wine Making Equipment:
When learning how to make homemade wine secondary fermentation is the anaerobic stage of fermentation, because you will use a carboy and an airlock. These two pieces of wine making equipment are needed to keep the air out. This process is much slower than primary fermentation, only 30 % of all of the fermentation activity occurs during this stage. This stage can take anywhere between 14 to 21 days depending on how much of how much sugar is still available. The activities of the fermentation will diminish on a daily basis due to the reduction in air causes the yeast to stop multiplying. Alcohol production will also reduce proportionately.
