Recipe
Step 1:
Bring the water to the boil. Add the sugar and let the tea steep in the water.
Step 2:
Allow the water to cool to a temperature not exceeding 30 °C and add the vinegar. Then pour the liquid into a plastic container and add the cut pieces of scoby. Cover the container with a cotton cloth.
Step 3:
After 3 weeks a new layer of scoby has formed and can be removed from the container. Clamp the scoby in the wooden or cardboard frame using clamps or nails. After drying for 1 week, the leather is ready for use.
