15L Hot (20L Cold) Fill Wine & Fresh Wort Kit Bladder / Cask

Stop wasting time chilling home brew wort. These bladders/bags are ideally suited to brewers who want to save time and avoid chilling wort on your brew day. Simply fill with hot wort and screw on the cap.

Hot Fillable
These bladders can be hot filled with any liquid up to 100°C. But from our testing in regards to bitterness levels, we are able to fill at 80°C to lock in that specific IBU we’re chasing without also changing the aroma hop flavour.

Capacity
These bladders have a maximum 20L Cold Fill Capacity. Meaning you can fill to 20L with cold liquid.
If you are hot filling, we only recommend to fill to 15L so that it is more malleable and less likely to burst or rip from “overfilling”.

Triple Layer
The triple layer construction consists of:
Layer 1 – 50micron polyethylene (PE)
Layer 2 – 45micron polyethylene (PE)
Layer 3 – 15micron nylon
Layer 1 gives the bladder the best possible chemical resistance making this bag suitable for a wide range of beverages. Layer 2 and 3 are laminated together for strength, puncture resistance and also to give the bag superior oxygen barrier properties keeping the liquid fresher for longer.

Absolutely Sterile
These bags have been irradiated so they are absolutely sterile. So you can fill hot wort into this bladder with absolutely no fears of infection from the bag itself.

Stop wasting time chilling wort!
Why sit around chilling wort? Put your hot wort directly into this bladder and screw on the cap. This enables you to make your own fresh wort kits and store the wort for later.

Long shelf life
The high oxygen barrier in the membrane makes these bags suitable for storage of wort for 1-2 years. This means you do not necessarily have to fill your fermenter on the same day as your brew day. Stockpile wort when you have time to make it then ferment out the wort when you have time to ferment it. Hot cubing gives you more flexibility.

Always got the right size bag for the job
In the past if you wanted to use the “no chill” method of brewing you would put your wort into a plastic HDPE Cube/container. These cubes were often the wrong size for the job. Bladders can easily be filled to the correct volume and used to store anywhere from 0-20L of hot wort.

Reusable
These bags are priced cheap enough that you can probably just throw them away. With that said if you wanted to clean them and then boil them to sterilise the bags there is nothing stopping you from using these again.

Easy Closure
Unlike most other bladders this bladder just has a screw cap making it easy to fill and cap.
