Different flavor profiles can be achieved with temp.• Use a clean towel on top of opening to allow oxygen to help ferment, but leave dirt and dust behind. Secure with rubber band.• A new SCOBY will form with every brew. Store old SCOBYs in a SCOBY Hotel. A separate vessel full of just aging SCOBYs.• Be clean and sanitary.
  23. 23. Adding Flavors and Bottling• I add fruit juices and flavors at bottling, using the sugars from the juice to help with bottle conditioning and carbonating.• Use fresh juice when possible.• Avoid juice with preservatives.• Can add different combos and amounts of juice and herbs to individual bottles for easy experiments and recipe creation• Test bottles after 3-4 days for carbonation levels until level is achieved. Then refrigerate to stop the process.
