G'day geniuses, I have started using the bladders from kegland which are pre sterilised to hot cube. I used one for the first time last weekend and it worked out okay but I have a couple of concerns, first is I am worried about high bitterness due to it staying so hot for so long, secondly it is hard as hell to get the beer in and get all the air out when the wort is eleventy million degrees and you are holding on to a plastic bag with no insulation because once you get to that point you need to get that lid on before you end up in rhe burns unit. My question is, if the bladder has been pre sterilised and therefore taking away the need to sterilise with heat is there anything stopping me from cooling it down to say 40 with a wort chiller prior to putting it in the bladder? Thanks team.
