Touch that keg and all your lagering efforts will be screwed - powdery miserable floaty hell of yeast it is. Plus it has the added "bonus" of being actively nasty tasting in suspension as well. I love kolsch - I love to brew kolsch - but honestly, I have never ever had an unfiltered kolsch that didn't taste bad. Homebrewed and commercial examples both.
Style guidelines say that traditionally kolsches are filtered bright ... and there is a reason.
Some people might not mind beer that tastes like vomit - but me I filter it instead and wouldn't make it if I couldn't.
