There are 2 methods, both of which are very effective. Note that you should leave the barrel or container open at the top so that air can circulate during fermentation.

    Filter out solids and retain only the resulting tea.
    Spray with a spraying bottle or sprayer.
  • The second option is to directly throw the leaves in boiling water, which will jump-start the maceration process. Firstly, boiling breaks down cell structure. After that, yeast drops in from the air around and gets right to work.
