10 x 15L Hot Fill Wine & Fresh Wort Kit Bladders / Casks
KL18463
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.
Sold in Singles Too
We do also sell this product in a single bladder so if you do not want to purchase a box of 10 you can purchase just one unit here KL18821.
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.
SIZE
When the bladder is flat the size is approximately 60cm x 46cm
Do you want to purchase just a single Bag?
If you do not want to purchase a box of 10 bags you can also just purchase a single bag with the part number KL18821. Please be aware that when you purchase a box of 10 bags you have the advantage that the whole box of 10 are irradiated ensuring the contents of the box is sterile. If you order these bags in singles we will have to take the bags out of box. The inside of the bag will still be sterile but not the outside surface.
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.

"Really strong , pretty convenient to use , a cap with a ball lock connection would be nice. Exceptionally strong I tested one filled with water and dropping it on an old concrete path the concrete cracked and the bag held up, great for storing grape juice."
"These things are great for a quick brew day or when doing a lager in summer when you can’t chill to pitching temp"
"Needs a good frame, I think. Get the tap with it for ease of use."
"These are great. Makes cooling wort very simple and reduces any need to clean, speeding up the whole process"
"Have used 17 times so far and have just ordered another 20. Easy to use and already sterile interior. Much easier than cleaning and sanitising a cube. Apparently can be reused if needed but I have not tried this. I went to no chill as I can brew when I have time and not be dependent on availability of fermenters or fermentation chambers."
"I haven't used them yet so not sure how they will hold up but for the price they are worth giving a go"
"👌 awesome"
"These bags are perfect. Easy to use."
"Great device, keeps a full brew ready to tip in the fermenter at any time, saves chilling time and water. Well worth it!"
"I use these bad boys all the time. I regularly get at least 22 litres into them without ever having one fail on me. Would recommend if you don't have the storage space for cubes."
