This is my first time brewing, so perhaps this is normal. To recap, I made a 'mead' by using coconut juice instead of water and adding about 100 ml of honey (so I think far less than normal). Perhaps you won't call this mead. I am totally inexperienced. I mixed three heaped tea spoons with the warmed mix of honey and coconut juice. Then I injected the lot back into coconuts and put on air locks. I fermented the mix for about 5 days inside the coconuts. When the balloon (home made) 'airlock' deflated I took the juice out. It seemed alcoholic.
Now I put the lot into a coke bottle. There was quite a bit of sediment at the bottom. I had to open the bottle a few times to allow some of the build up of gas to escape. After a couple of days I got inspired to add cloves, ginger, cracked pepper. A couple of days after that I foolishly thought I might be done (total inexperience) and transferred the mix, less sediment, to small plastic bottles and shoved them in the fridge.
Just a few hours later, after reading more, I realised it would take months to make anything. So I took the reduced liquid (the sediment, ginger, etc all thrown out) and put it into the coke bottle with the balloon to stop it bursting.
All in all the stuff had only been in the coconut 5 days and in the coke bottle, bubbling away, for another five.
Now things got interesting. The balloon inverted, showing that the mix was eating oxygen but not producing the same volume or carbon dioxide (or whatever). There is a serious vacuum in the bottle. There is a layer of sediment at the bottom. Also about 1.5 inches down there is a layer of sediment. The liquid is otherwise clearing. It is the colour of white beer.
Can anyone tell me what is happening?
