decarbonating a brew

[Maylar]

What's the quickest way to make a beer or cider go flat?
I want to use some brew to purge the cleaning water out of my filter pads, and the pump doesn't like bubbles.

Ultrasound. It makes the CO2 run for the hills like nothing else. But it's one thing if you need to decarbonate a small sample for analysis, if you do it with a keg you'll end up with all the beer trying to get out of the keg like there was a fire inside...

Umm.. thanks, but my ultrasound machine is not working right now

Well, you did ask for the quickest way, didn't you?
The slowest way on the other hand is to open the PRV on the keg and just wait for it to go flat. It can take a while...

this what you meant?

What about surface area? pouring into a shallow pan or bowl

If you're degassing in a carboy or bucket, you can use a wine whip.

Since you probably aren't going to want to drink this beer after use, why not just boil it, and let it cool. Or, does this have to be done with the beer in a keg?

Brew on

When using a Buon Vino Mini Jet filter the pads get saturated with water and you have to purge that out before filtering your brew. You lose a cup or 2 in the process. That sucks if you're just filtering a gallon. I'd rather sacrifice someone else's brew than mine.

I'm only talking about a bottle at a time. Like taking a bottle of cheap commercial cider and letting it go flat. No, it won't be consumed afterward. So I guess I'll just pour it into a mason jar and stir it up once in a while till the bubbles go away.

I wish I had a vacuum pump.

No, I meant something like this. They're great for getting your glasses and jewelry spotless as well.

Not a very good idea, unless you want to turn the vacuum pump into a "foam pump". The latter are much harder to keep clean...

$4 dollars or $40, both are affordable....lol, i'd image a ultrasonic tub would be better then a submersible for flattening a beer quick!

If you're looking to flatten a single bottle, pour it back and forth between glasses a bunch of times. Or put into a vessel that'll hold pressure with a twist top (soda bottle will work well), and shake then vent then shake then vent.

For larger volumes (like a keg), you can burp in large bubbles of CO2. Depressurize keg to near zero, add gas through bottom (liquid out post) at pretty high pressure in bursts (say blow in at 30 PSI for a few seconds at a time) until keg is like 10 PSI, let rest, then repeat process. It ain't good for the beer but it's fast.

The reason you dump the first 2 cups of filtered beer is because it will be mixed with the water the filters have been soaked in. If you purge the filters with cheap cider they will become saturated with it and the first cup or two of your beer will be mixed with the cider. I would hardly see it as an improvement over mixing with water and I would still throw them away. Basically, IMHO you're just wasting time (and cheap cider).

I'm filtering cider, not beer. I should have mentioned that up front, sorry.
