Let's not go there in this thread please.

What I find interesting about the video having watched it is Kee saying the all rounder can be used as a keg, yet only a week or so ago he was rubbishing the oppositions Junior fermenter/keg saying they can't be used as a keg!

Easy, tiger!

That’s all very interesting but I still am not clear about, irrespective of what vessel you use as a pressure fermenter, (SS for example), is it ok to leave the beer on the trub/dead yeast/yucky stuff in the bottom for 2-3 months while you pour your pint from said pressure fermenter? Yes or No would be good.

No.

Thanks @foxy . I must say that was my first thought but got confused by this claim of being able to use the Allrounder as a serving keg.

I have the fermzilla conical and I fit a intertap to it to serve.I also fit a tapcooler counter pressure bottle filler to the intertap to fill bottles. It is brilliant

It is a unitank

Hi @Justin Dean . Are you saying you serve your beer off the trub from your PF? How long does it last?

When doing this, do you avoid oxygen contact with the beer? I filled a couple of bottles from the keg last week and when my mate got them, he said they hadn't travelled well. A bit on the flat side.

I have the fermzilla conical so i can unscrew bulb at bottom to remove trub.
Yes it is a closed system so no oxygen.

The tapcooler counter pressure set up lets you flush the bottle with co2 before filling.Got it from malt miller. It is really good piece of kit for bottling from intertap etc. Check it out. If you are pressure brewing and want to bottle in sealed system it is worth the investment.

I know this is an old thread but i am thinking of moving into this type of fermenting. My original plan is to have an allrounder that will fit in my fermentation fridge as primary fermenter. Once finished fermenting cold crash and carbonate and then using beer gun bottle. does this seem doable or am i missing something as for dry hopping is it ok to just drop them into the fermenter and repressurise or make hope and use a carbonation cap on another bottle and transfer that way
Thanks for any help

I have an allrounder (which by the way, I really like) but find bottling a real pain. I don't have a beer gun, though I tried a cheapo one off Aliexpress and found it really awkward to use, so have tried bottling either with a picnic tap and a bottle length of tube attached, or using a bottling wand on the end of a length of hose. I found it possible to do 8 or so bottles, but more than that would be hard work, though I'm sure those with Blichman type beer guns will have a different view.

I've done dry hopping via a hop tea in a 500ml fizzy water bottle with a couple of Kegland carbonation caps attached to it and pushed in through the liquid out connector and I've also tried putting the hops in a mesh bag supported with magnets, which are released when I want the hops to fall into the brew. I prefer this method to the hop tea.

It depends on your brew but I don't think you'll suffer too much by taking the lid off and chucking them in and then resealing and squirting some CO2 in, but my lid is very tight and hard work to get off, so not something I choose to do unless absolutely necessary.

Pardon my ignorance but if the contents of a PET bottle is at a higher pressure than the outside air, how can air oxygen permeate to the inside of the bottle? I would have thought the gas in the bottle would be trying to escape into the air. That is the principle of a Hazmat suit

Thank you for that insight foxy - bit heavy but I read it. So questions - How long do you think it is reasonable to store beer in PET? I use these bottles as they are relatively light in the motorhome but this year I have not consumed as much because we have been house bound more, and secondly what effect would over carbonated beer have on the oxygen transfer?

From what I understand temperature and UV has a lot to do with it and the PET breaking down. As I mentioned the Coopers PET bottles have a barrier film I am pretty sure that their bottles are good for a year. Their is the same problem with crown caps, they too let in oxygen.

We have just completed the first phase of tests where the same beer was stored in stainless and in PET kegs in the same fridges. If anyone wants the reports I can make them available here.
