Rye flour paste is the traditional method used by moonshiners to seal seams on copper moonshine stills.

If a still has not been sealed properly, vapor will escape from the joint. Alcohol vapor is explosive at high concentrations. So, always seal your still and never distill indoors.

  • 3/4 cup rye flour
  • 1/3 cup water
  • Mix the rye flour and water together with your hands
  • Roll the flour paste into a snake

Once the boiler reaches 115 degrees apply the flour paste to the still
As the still heats up the rye flour paste will cook onto the still creating a seal at the joint
Keep an eye on your still to make sure that alcohol vapor is not escaping from any joint. Re-apply paste if needed.
