yeast in glass and after taste

[BMWMK2]

i brewed a belgian noel from ahs in october which called for two containers of white labs yeast. when i racked it to the keg to condition i did notice some suspended yeast but figured it would drop out and come out in the first glass as normal. now im drinking it and there is clearly yeast coming out of the keg even after i pulled a few pints, there is yeast in the bottom of the glass also. could the yeast be causing a metallic bitterness in the beer? the keg has been cold crashing for a few weeks now should i rack of the top to a new keg and will this get rid of the aftertaste? i dont use bleach and i use a keggle to brew in and non of the other 20 batches i made have this taste so i dont think its my process or equipment.
thanks

Metallic taste is sometimes caused by the wort coming into contact with unprotected metals. Are you using a new keg, or did you aggressively scrub either it or your kettle while cleaning? I haven't experienced it myself, but I've also read that poorly stored malts can sometimes produce a metallic off-taste.

Strange about the yeast. It should fall out of suspension after being chilled for some time in the keg. Like you said, it's not unusual for the first several pints to have a good amount of yeast in them, but it certainly shouldn't be every pint. Although the yeast will settle to the bottom of the keg. If there was a lot of suspended yeast when you kegged and your dip tube goes all the way to the bottom, you could suck more yeast for longer than usual.
