Just bottled my first batch of beer and I was wondering what exactly is the stuff at the bottom of the fermentation vessel. I thought it was yeast/sediment. It tasted pretty strange sweet yet bitter taste and seemed to foam when tasted.
What is it exactly?
Additionally, when bottling, the last few bottles had extra sediment in them as I had to tilt the fermentation vessel, is this good/bad or it doesn't matter? Any way to overcome any problems with this sediment when bottling?
