I'm trying to find a very cheap option to cool my beer, mostly because i am leaving my country after this summer and what ever i buy will only be used a few times. So my budget is around £10-£15
I've tried putting my fermenters into double binbags and filling them with water and ice bottles, but the water leaked out. tried tying a double knot in the bonded end of the bags, still leaked out somehow... right now i have it in these bin bags with no water and just as many frozen water bottles as I could but its still around 23*C :/
I've looked for cool bags/boxes but can not find anything big enough, am now looking for a regular plastic box that can be big enough although no luck yet, or considering to use a polystyrene box but i fear it might also leak....
does anyone have any suggestions? To be honest I really dont get why it is so bloody hard for me to find a water proof bin bag... but anyway
