Filtering? Is this possible?

Postby new2brew » Thu Aug 13, 2009 7:00 pm

Can someone tell me if this is a feasible idea...

I racked my Canadian Ale into bottles and two 5l mini-kegs. It has been conditioning/carbonating for a while now.

Would it be an ok idea to transfer the beer from one mini-keg to another and filter it in the process, thus removing some of the floaties/by-product that is in there?

I imagine I would need to boost the CO2 in my kegerator for a little while after it's been transferred and filtered.

Any suggestions?

Thanks

There really shouldnt be anything floating in the beer after it sits awhile. You could kust rack it from one keg to another leaving sediment behind. If the first keg is in the fridge for a couple days and you dont shake it or stir anything it should be clear to transfer.
And you should just keep the co2 at the same and it should not loose too much co2 during the transfer. You can use a paper towel to keep the keg being filled under some pressure by wrapping it around the racking tube. I use a rubber stopper around a tube when i fill bottles and growlers from my kegerator.

Always filter prior to carbonation else you'll end up with nothing but a foamy mess.

Ok, so if I try to filter it first on my next batch won't the yeast get filtered out?

And I guess to be more clear I want to filter out the sediment at the bottom. I can see it in the bottles and assume it's in the mini-kegs too.

After your beer is done fermenting, there really is no need for the yeast if you are force carbonating. So, yes you would be filtering out the yeast, which is what is causing the sediment.
Another easier option would be to rack your beer to secondary after it's done fermenting and give it a week or two to clear up before kegging it. Keeping the secondary cold will help speed the process.

As long as you naturally carb your beers i.e., bottle/keg condition, you'll always have sediment on the bottom. This is due to the yeast settling out of your beer and going dormant. The yeast is necessary for carbonation. You'll notice this in bottles of bottle conditioned beers from the store. The only thing filtering will do is aid in clearing your beer the same way finings or crashing will do. If you absolutely must avoid the yeast, decant from the bottle into a glass. If tapping a conditioned keg, after the first two pints, the rest should be clear.
If you still want to filter and then plan to naturally carb, don't use a filter smaller than 1 micron.

So I opened and consumed one of the mini-kegs and didn't realize any sediment in any of the glasses. (although it was a party and we were using plastic cups :wink: )

So for the most part I think the filtering question is moot.

Thanks for the help from everyone though.
