Mad Millie have selected the finest commercial cultures to be professionally packaged in convenient 8L (4 US Gal.) sachets for extra quality control and convenience.

Each sachet has been freeze dried and nitrogen flushed to ensure a shelf life of 24 months when kept in the freezer.

Once sachet is opened, it is recommended to purchase a Sterile Pottle to keep your left overs stored in a safe, sterile way to reduce the chance of culture contamination.
