Default Dip tube in corny keg sucking up yeast. Cut it?

I just switched to a 4 corny keg kegerator system and have noticed that my last three kegs are really cloudy. I use ball lock kegs that have a little depression at the bottom where all the yeast settles.. It;s also right where the dip tube sucks my beer from. As a result they are all cloudy..

Just wondering how you guys resolve this issue in your corny kegs WITHOUT adding a filtration system.. Should I cut an inch or so off the dip tube?

if you let the kegs cool in the kegerator for a little while, all of the yeast will drop out to the bottom as you say, then you draw a pint or two, which will be cloudy...then your beer from then on out should be relatively clear. If you just switched, it could be that you're running into chill haze which you aren't used to. That happened to me. I was drinking all of my beer at 50+ degrees, and it was clear. Got them into a keg in a cooler and suddenly my beers were hazy.

I keg mine for 2 weeks at 40degrees while carbonating, and all the yeast comes out in the first pint. Running beer through a secondary before kegging helps also.

I cut an inch off the bottom of all my dip tubes. And it seems to help.

I didn't cut mine, and I'm happy with them. The first couple of pints have some sediment, but the rest are clear. Also, when the keg is empty, I have almost no beer left in the keg- just a little bit of yeast sludge that is compacted to the bottom. I don't "waste" any beer at all, after that first pint.

If you move the kegs around, of course the sediment will re-stir up. I wanted a super clear keg to take to a party, so I "jumped" it with QDs and beerline into a new keg. That left only clear beer, and almost no sediment at all in it when that keg was done.

there shouldn't be any reason to alter the tube, its nicely designed to get every last drop of beer out. As previously stated, getting beer cloudy with yeast is normal for the first couple of draws. If its properly chilled, just pump out the yeastie part, dump it or tough it up and down it

One thing to do is make sure you don't disturb the keg once you start drawing from it. There may be a bigger yeast cake in there, you want the diptube to draw out the middle part of that cake, the sides of the cake should stay undisturbed in the bottom of the keg. Guess you could shake it around and draw out all of it if you want.

But chill-haze is different if that's what you have. I give my beer a headstart on clearing up by putting the primary in keg temps (40F) a few days before kegging it. You'll settle out more yeast and haze that way.

I really wouldn't mess with the tube if its centered properly on that lowest indentation. Cutting it won't really solve any big problems and will create other problems. Namely the seated security of the tube, and the inability to draw out all the beer.

cheers and good luck! happy kegging

I dont waste any beer either when mine are empty there is very little in the bottom, If U dont cut the tube and take the first couple of pours from the keg and dump em because they have to much yeast/ sluge then what is the difference U still waste some. My thoughts anyway.

Ya but soda dosnt have yeast sludge in it. And it will solve a big part of the problem but not all and how could cutting an inch off create any other problems? What would it have to do with the ( seated security of the tube )?The tubes is still going to seat even if it is a inch long.

The tube-end seating isn't such a big deal sure, but it helps prevent any possible bending of the tube.
But by cutting the tube, you will be leaving all the yeast in the keg, which you may or may not want, and you get 1 inch less beer
It just seems to me that its counter-productive.. the full-length tube in fact helps you get clearer beer. (just not on the first pint or 2)
I haven't tried shortening any tubes though so far so hey keiths could be totally right. I do get very clear beer though.

Cheers

I have cut the dip tube on some of my kegs and not cut it on others. Here's my take:

IMO/IME, you are not wasting beer by cutting a dip tube by 3/4" or so. Any additional beer that you would get by not cutting it (and it's less than you think) would be cloudy anyway. Either way yields the same 'last clear drop' IME.

Kegs differ. Some kegs have the little 'well' in the center and the curved dip tube goes down into that well. Some dip tubes go deeper into that well than others. Sometimes it doesn't actually extend down into that well and sometimes the dip tube has been turned (by tightening) such that it's not in the well anymore (due to it's curvature). Other kegs have an offset well and a straight dip tube...again, some that go deeper than others. Point being that kegs can vary quite a bit in how close to the bottom surface that dip tube goes.

Beers differ. Some beers have more yeast/sediment than others and some yeasts settle into more tightly-packed-cakes than others. I just bottled-from-the-keg two weizen beers because I didn't think I could get a consistent pour from beginning to end (without shaking the keg or something). I was always pulling the yeastiest stuff from the bottom.

So, IMO, certain kegs filled with certain beers would benefit from cutting the dip tube and others wouldn't. But it usually doesn't hurt anything and again, IMO/IME you are not wasting beer by doing it.

FWIW, I cut my dip tubes at an angle so it pulls from the side a little bit.

Can you explain? This seems backwards.
