This extension kit allows you to easily double up any batch. Here are the steps:


  1. Save money by ordering a 48 bottle refill rather than 24
  2. Brew all of the beer ingredients in your 18.9L / 20 qt stainless steel brew kettle
  3. Ferment in the starter kit bucket, as well as this one provided in the extension kit
  4. Bottle and enjoy!*


24 extra glass bottles (355 ml) are included.
