Last night I brewed a very basic Hefeweizen. I mashed 6kg of Wheat Malt and 4 Kg of pale malt. My first runnings came out at 1.075 and whilst I waited for the sparge and second runnings I started to boil the first runnings. By the time I was ready to add the second runnings the boil had become quite vigorous but there was a strange scum/foam on top of the wort which I decide to take out with a slatted spoon. When I did this I removed huge congealed clumps of what I can only assume were congealed hot break particles - to be honest they looked just like cooked whole chicken livers and the texture wasn't much different. Whilst definitely not professing to be a seasoned brewer this was my 58th All grain brew and it is the first time I have see this. Was this just a unusual hot break or is there something ominous I should be worried about?
