Upon opening a Morgans Blue mountain lager the contents spew out of the bottle. It taste like apple and is ultra carbonated. This has never happened before so am thinking it is an infection of some sort. problem is this was the first yeast which I harvested for 2 more brews after that I had the current brew using the same yeast lagering for 6 weeks and I had to keep loosning the cap to relieve the pressure about once a week whilst it was lagering which I thought was odd ?.
am currently giving the fermenter a good sanitise. Does anyone know how to pull the tap apart ?
They are all lagers brewed at 10 C then temp risen to 16-18 to finish them off and the D rest. They also tasted a bit sour but looked ok in the bottle with no gunk or film on the top. once bottled after lagering they were left at room temp. Have done 4 batches the same as this without any probs, so if it aint an infection then I dont know ?.

The advice above to put it in hot water to soften it up helps. I unscrew the tap from the fermenter, turn it about ½-way on, and put a bit of doweling into the tap from the back. Then hold onto the tap body, and give it a sharp wack onto a firm surface. The dowel should push the tap inner out. You can then clean it. Reassemble simply by pushing it back together.
Firstly, as an aside I would recommend lagering at closer to 4-5C if you are only going to be lagering for 4 weeks. This accelerates the conditioning process and will be much more noticeable.
Hmmm, with that long in the fermenter I doubt there is any excess sugar unfermented.
Maybe an infected bottle, you could try another perhaps? Infected batch is a possibility I guess but it doesn't sound like it.
I don`t bother pulling taps apart for cleaning- at $1.56 from Bunnings if it looks a bit stained or suss I just throw it to buggery and put in a new one.
