Grab your SCOBY and head to the Chilmark library on Wednesday, Jan. 17, for a free kombucha workshop. Nina Gordon of Kulture Club M.V. will give a demonstration on how to brew small batches of kombucha at home. She’ll discuss the process, ingredients, equipment, and variables affecting kombucha fermentation, the biology of the SCOBY, and the potential health benefits. A limited number of SCOBYs will be given away to attendees. Bring a watertight vessel with a lid. Begins at 5 pm. For more information, call 508-645-3360.
