Just thought I would point out the cheapest 1 gallon DJs and airlocks with bungs to save people time and money, I use these and they are good.

For plastic demijonhs you could go even cheaper. Just buy some 5L water bottles for half the price plus some grommets and drill a hole in the lid and stick a grommet in it

I dont bother with an airlock.
A small freezer bag over the top and handle
of the Ashdown water PET secured with a
steralized rubber band that posties drop
everywhere - never had a problem yet.

I have read if you use a 9mm drill you don't need a grommet.

Ask down your local chipshop if they buy in mayo or curry sauces, these come in sealable 5-25l buckets, a good cleaning and you have as many fermentation bins as you could ever need for free.

Yeah works fine, especially if you rub a little petroleum jelly round the outside to seal it.

Or you could forget drilling grommets and airlocks if you loosen the cap a turn. Did about 10-15 batches in the asda 5l water bottles with a loose cap. 0 infection s.

Be careful doing that, I've had a wine kit blow the top clean off. Luckily was only gas pressure so didn't decorate the walls and it was going like the clappers so didn't get infected.

Thanks for the thrifty tips!

Silly question but do you need to prick the bag with a pin?

No need to, the slight pressure blows off past the rubber band every so often,
but the bag is airtight when the fermenting slows down and stops.

You can build a ring with blue tack and press that in like a fillet weld, too.

If you've got a step drill you can drill a 28mm hole and put the whole big bung into it. You don't even need to attach it to a drill, just twist it by hand.

Good tip - I didn't think to do it by hand and instead used my drill they are a bit fierce so be careful if you get one

Amazon has 'm too, under £2 when you buy by the 10.

Mine leak gas out of somewhere. airlocks don't bubble properly. doesn't really matter cos you can see the bubbles going up the sides as we know, and there's always 'Mr Hydrometer'. Still not such a satisfying 'bloop' noise every now an again like my glass ones do.
