These look fantastic.No worries at all. Well seeing as we have some interest and we got some private message about this product we have ordered these and they are going to take a few weeks to get made up for us. The bladder suppliers do not normally make this screw cap so we had to order a couple thousand just so they would make them especially for us with this closure type. They will looks like this:
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.www.kegland.com.au
As you can see they only cost $1.60 each if you purchase a box of 10. The freight will be a lot cheaper than sending empty 20L cubes around the country.
I am a bit embarrassed to say this but I think the days of me washing out cubes is probably over. As much as I like the idea of reduce/reuse/recycle to minimise the impact on the environment I think a small amount of plastic film used to make 20L of beer might just be the compromise I have to make.
If you specifically wanted to test these out and get back to us with some feedback then PM me and we can organise some free ones for you when they come into stock.
Real space savers when not in use too.
