Turning a king keg in to a fermenter

[rich.1980]

Hi I have just got two king kegs for free and was wondering if I could modify one to take a air lock and use it as a fermenter unit

In theory yes, ultimately its a 5 gallon food safe plastic bucket so if you could fit an airlock I cannot see any reason why you couldn’t.

No need for an airlock!
On my usual fermenter, I just leave the lid fastened loosely. With a king keg, you could use a piece of muslin cloth or a clean teatowel fastened with an elastic band.

I do put an airlock when used as a fermenter.
Also they work well as kegs the connector still works without the bag in them.
Also when damaged and cut up you can make two mini greenhouses out of them.

modded my king keg works a treat

I've got a couple that I don't use anymore, and was wondering if, fitted with a spunding valve, they could be used for pressure fermenting?

 

[RoomWithABrew]

Apologies, thought the OP said key keg which are disposable.
I have fitted a bulkhead ball lock gas connection to my king keg and spunded some ales.

Absolutely yes.

Hi, I totally get this if you have a keg already or you gonna get one free etc... Question i have is this, would you purchase brand new one with the intention of turning into fermenter and of course have it to serve brew from?

Good idea to use a cable gland like that

Apologies, I may have misunderstood what you mean - but you can’t really serve from the same vessel you fermented in, because if you leave the beer lying on the sediment too long you’ll get ‘off’ flavours

Nah, I think I may have complicated things a bit..... what I meant is this,
I totally understand using a king keg for a fermenter, I have been wondering the same thing. That is assuming you have one around or be getting a keg for free. I was interested to see if someone would purchase a keg for that purpose in addition to having it as a serving vessel, not necessarily to ferment beer and serve it right away from the same vessel. But to have it as a fermenter if needed and then in some other cases to condition homebrew in it...

And I am interested in that since it cost the same (more or less) as 30l chubby.... in some cases king keg is even more expensive....

Great - thanks; just thought I'd better check :-)

Again apologies if I've misunderstood your objectives, but for fermenting I think it's hard to beat the 25 or 30 litre food grade buckets for under a tenner :-)

e.g 25L White Bucket with a Metal Handle & White Lid

But I can get a fermentasaurus for 30 pounds.
However barley wine going well in a bucket.

Wide mouth fermenters for just over a tenner are my go to.
