However, with nutrients added into the pre-fermentation must the fermentation time can be dramatically decreased. The Beverage People Mead Nutrient contains the nitrogen, minerals and vitamins needed to get your mead fermentation complete, generally within a couple weeks. The Mead Nutrient contains:
Another nutrient your yeast will need but cannot be put in this package is oxygen, so don't forget to aerate!
