Dip tube on co2 post?

[bcornell11]

Hello all,
We're kegging a margarita mix and wanted to see if was possible or useful to use a dip tube on the co2 post so it would hopefully keep the margarita mix agitated and not settle at the bottom of the keg. It's about a 4 hour event so not sure how much settling would occur but thought this might be an easy solution. Thanks for any tips or advice

Welcome to the forums at Homebrew Talk, @bcornell11

Keeping kegs stirred up would be an unfamiliar paradigm for beer brewers who prefer letting anything that settles to just lay down and stay down

That said your idea likely has some merit, with the caveat that a mistake could flood your gas regulator with margarita mix. Once you've put pressure on the keg you can't lower the pressure at the regulator lest the keg headspace pressure override the lowered regulator pressure and drive 'rita up the long dip tube and gas line and into the regulator.

If your regulator has a "back-flow preventer" aka "check valve" (often integrated in the shut-off valve) it can prevent the worst of that as long as there is sufficient gas tubing between keg and regulator to account for compression...

Cheers!

I have check valves integrated into the ball lock connectors which work well.

Can't you just agitate the keg though to keep it stirred up over those few hours?

Not sure that much settling will occur in 4 hours though.

Appreciate the replies and probably overthinking the possible settling over a short 4 hour service. It's actually going to be the last beverage off a 3 way secondary regulator. The first 2 beverages will be beer served at 10-12 psi and the margarita at about 7psi. Probably forgo the co2 dip tube and give it a good shake prior to hooking up.

Hit it with 35 psi of CO2 then store it upside down until ready to hook up and serve.

what is in this margarita mix that needs agitating?

Suppose you put a liquid connector on your CO₂ line, and just hit it with a blast through the liquid out post ever time the keg pressure drops below a decent serving pressure. It might be a little inconvenient swapping connections on/off, but should work if that’s what you need.

Just shake it from time to time.

It's a bit of a hassle to do, but you can also attach a black (beverage) disconnect to the co2 line from the tank, and thus run co2 into the bottom of the keg through the liquid-out post; a short blast should do it. This is how many people force carbonate in cornies. I'm assuming that your margarita mix won't be carbonated to begin with?

Also if your margarita mix has pulp from the limes (or whatever fruit) in it, I would be concerned about clogging the dip tube in the keg.
