No Chill Cube

Postby Hardboil » Sun Mar 18, 2018 16:32

Hi All,


in the brewhouse today brewing an English Golden Ale. I purchased some 25L cubes after seeing them used by a distiller (small scale)
to cool and store wort for another day.

Rather than pop my coil in the boiling pot or run the wart through my plate chiller, I opted for not un-freezing the outside tap and using the cube. So far pretty good, I flooded the cube with C02 before filling, made sure it was clean and sanitised and then filled the cube with as close to boiling wort as I could.

Its currently laying in a big pile of snow lol. Dropping about 30" per hour (23L batch). I expect that to speed up as it gets closer to my target temp of 18'.

I have a good strong starter ready, it has been going for a couple of days to make sure once it goes into the conical the yeast can get going asap.

Worth considering if water is an issue. I will report back if I get any strange outcomes.

thanks HB

I have a couple of cubes that I have used with no problems. What I tend to do is sit them in the corner of the living room to benefit from the heat they radiate!

I’ve got some 25L cubes that used to have renit in them.

Are they likely to be ok as FVs? - just wondering if you ‘cube’ people know.

2016: 330L brewed (72 gallons, over 8 firkins)
2017: 105L brewed (need to update this figure)
Drinking: Landlord clone
Conditioning: ciders from 2016, hedgerow barrolo, 1914 Courage RIS (10%).

I can think of 2 issues with that.
1 you want it as full as possible to prevent it warping as the wort cools.
2 cleaning it out properly.

If you've got both of those covered then I can't see any issue!

Thanks for the input - was thinking more just as a FV rather than using it to cool the wort as the plastic is likely not rated for near-boiling liquid.

The cleaning issue is the biggie. With warm caustic then PAA, it ‘sound’ be ok but you never know. Just worried about 20L of wort being tainted
