Default How much beer is left in the keg??

New to brewing and kegging and want to know; how will I be able to tell how much beer I have left in the keg??? How embarrassing would it be to have friends over and only be able to serve a few beers before nothing is left...I don't want to be that guy!!

I would assume that I could take the empty keg weight and use that weight to know when I am getting close to empty. But is there an easier way???


thanks

Doug

Don't be that guy! Have multiple kegs ready or lots of brew bottled.

To see if the kegs are near the end of the line I usually just open the kegerator and give it a lift, heavy kegs are good, light kegs are good to put more beer into.

You can get temperature strips that run along the side of the keg. you wet them with warm water and they'll cool faster where there is liquid, which ends up with a color-change mark on the tape.
Or you can do what I've done and build electronic scales for each keg which are then calibrated into pints left, which is shown on a panel by the taps

It's easy to tell if the humidity is high. Open the kegerator for a few seconds and the outside of the keg will sweat from condensation only up to where the beer level is.

Otherwise, I just use the tilt method. I can get a good idea just by tilting the keg a bit.

Having another full keg doesn't do much since it's warm and flat!

In time, you will get a feel for when kegs are close to blowing gas by giving them a little lift.

When you pour a pint and it's super clear and it tastes much better than all the previously poured pints...well, there will only be 2 to 3 ounces left!

Isn't that the truth.

Estimating weight by lifting or being more accurate by using a large fish weigher and doing an current weight-empty keg weight to find the liquid weight and converting that to approximate volume works.

Same with temperature tests as mentioned.

The only difference with propane tanks is the lack of an inline gague.

I haven't actually used them but they seem like a cheap and easy solution and they are reusable.

Yep, that's them. I have them, and they work, but in the end found they aren't very helpful to me, since I need to pull the kegs out to get at the strips. I much prefer being able to know how much beer is in a keg without needing to open up the freezer
