Hey guys, im doing a small test batch soon and im interested if this 5L demijohn will hold the pressure with the lid on?
Has anyone tried this?
Thanks

Can't see i being a problem. Is it standard bottle thickness glass? Maybe test it, put it in the sink, plastic bag and a towel over the top. Work out the amount of pressure a bottle needs to take and add an appropriate ammount of backing soda and vinigar. See if it holds.

I had a 5l brown bottle I used for emergency space when I ran out of bottles. Only used it once and cracked it out for a party. Worked a treat.
 
My experience has been yes. The lids on mine will let gas escape before the pressure gets to a level that will cause any danger to the glass however (on mine).

I have several of these in rotation for mead, starters etc...some of the starters I have had in these have far more pressure than bottle carbing would get to (even for a weizen). I have a 1.5L Grolsch I use in normal bottle rotation and the glass isn't much thicker than the 5L carboys BUT the lid on the grolsch seals much tighter.

When you say you are doing a test batch do you mean you are fermenting in it with the lid on or are just going to bottle 5L of the batch into it?

YMMV.


Edit: your topic title implies bottling - bottling pressure, if you use the same detachble swing top that I do, no worries at all.

Hey Acasta,
Probably, but why?
If fermenting, why not just a touch of glad wrap & a rubber band? Cant see any benefit of trapping the CO2 (or trying to trap - I reckon it'll sneak out around the rubber anyway).
 
Just put alfoil on the lid - why seal it? Or an airlock? Or are you trying to ferment under pressure at higher temps (emulating commercial brewing?)
 
Its for bottle conditioning fellas, i know that cling wrap will be a good cover fermentation.

Im just gonna try it and see what happens. Im doing a small 5L batch, ferment in this, rack off to something, clean it out then put it back into the demijohn for conditioning.

Thanks.
 
Clingwrap should provide a good pressure relief valve. At first I thought you were going to seal it off completely and gas it up to VB levels nooooooooooooo.

And note the piccie in your avatar.

I would just exercise caution in storing of it, maybe aim for around 2 volumes, and after a month if its stable you are onto a winner.

Yeah thats pretty much the plan. Low carbonation, in the garage with blanket over it, when i open it making sure to have PPE on :p
