ok, so yesterday I tried to pour 2L into a jug. Don't think I could have made a bigger mess of it if I tried. It being very fizzy ended up with a jug full of head, and quickly running out of space in the jug. Then in a panic I am trying to grab anything I can get hold so I can continuously pour, luckily there were some clean glasses at hand.
With a jug and two glasses full of beer I took a sample from each. I can taste the sediment in all of them, even though they are still clear so not that much could have got through.
Comparing it to my smaller bottles it is worse. But even with the 500ml bottles I still find I can really taste the sediment sometimes. It seems that the smallest amount really affects the taste, unless its because I am really looking for it. It's this sediment taste that I associate with the "homebrew twang", or at least I think its the sediment taste, of course I could be completely wrong on this. Not very good at describing taste, but I would say it tastes kind of yeasty, but not like bread yeast and has a slight chalking feeling on the roof of your mouth.
I think I will stock up on smaller bottles until maybe one day I can get a corny.
