In just about every article on kegging that I've read they suggest pouring off the first quart or so before you start drinking. I've never bothered. I've tried but then I just shrug and drink it instead of dumping it. I haven't noticed much of a difference between that first drink and the rest of the keg. The same goes for bottles. The sediment at the bottom just doesn't bother me. Hell, half the time I just drink straight out of the bottle and drain them all. Considering that they actually sell "brewers yeast" as a superfood I don't see how this practice could be anything but good for you. Does anyone really get such an offensive sediment layer in their kegs/bottles that they even notice it?
