Just before Christmas my wife and I went to NZ, I had a friend house sit. I had two fermentors ready to keg so they did it for me, wouldn't you know it both are stuffed!!
One froze, fridge must have been up to high and it was touching cooling plate at back and the other they managed to get all the lees from bottom of fermenter in and it just tastes bloody horrible.
NO real question to this I'm just having a bitch, because I've now run out of kegged beer having drained the one good keg last night.
So word of warning don't let none brewers help if you're not there to supervise!!!
