The popular 5L Heineken mini keg is most often thrown away after one use -- the common belief is that the mini keg cannot be reused. Home brewers, however, can take advantage of this mini keg to create a convenient kegerator for prepared home brew. Easy to transport, you can then share your home brew with friends almost anywhere.

  1. 1

    Empty your Heineken mini keg completely and drill a hole (1 inch in diameter) in the top of the keg. Pour 5L of prepared home brew into the keg through the hole -- make sure to leave an inch of air between the home brew and the top of the mini keg for pressurisation.

  2. 2

    Prime your keg. Add 1/3 cup of corn sugar dissolved in boiling water to the home brew in the keg. Stop the hole with a mini-keg relief bung. This will keep any air from entering the keg and will prevent excessive pressure from accumulating while the home brew pressurises.

  3. 3

    Allow the keg to pressurise for three days in a cool location, away from sunlight. Before serving, chill the keg for several hours and then use the built-in plastic tap to pour your home brew.
