Cube size n Co2 flush

Post #1 made 12 years ago
I'm doing small batches 11 to 15 litre, I would like to 'no chill' and ferment in the cube. In the UK I have not found a supplier of 15liter cubes but I can get 20 litre cubes.

20liters would either leave a lot of head space or I would have to squash the cube a lot to get the volume down..

I have a Co2 bottle would it be OK to fill a 20litre cube to say 10 litres with hot wort flush the headspace with Co2 seal the cube and proceed as usual, sterilising the cube etc.

You don't need to bother. Just fill and squash down as much as you can. I often only get 20L into the 25L cube. Just make sure you turn the cube on its side and over again so that all surfaces are sterilised by the heat.

At this stage in the process exposure to the leftover air in the cube isn't a problem and when you are putting it into the fermenter later you want to shake it as much as possible to get plenty of air into the wort to get the yeast to start multiplying
