PLEASE HELP ME I AM NEW TO BREWING AND HAVE NO IDEA !!!
I live in Hong Kong and they have recently lifted the laws on home brewing, however there are no stores to purchase any supplies at all (only overseas with shipment 4 times the price of the actually supplies) - so i have tried my best with limited resources.
I pressed my apples then started primary fermentation. after 6 days i transferred to a second bottle for secondary fermentation - with a home made airlock (that i airtight - i tested) however this funny film has developed and no air is coming out of the airlock (please see photo)
Could somebody please try and help me figure out what has happened ???
thank you in advance
