Hi there. I am kinda new to brewing. I've done only a couple of the coopers can kits. And now I'm trying the Thomas coopers pilsner which requires a slightly lower temperature ... Trouble is we're having a heat wave here (33 degrees outside) so i am having trouble keeping it at 18-22. So I'm wondering a) what the realistic downsides of higher temps are and b) if anyone has any tips for keeping the temp down... I've put the carboy in a bigger box and I put some frozen water bottles in there from time to time. But any advice appreciated!! Many thanks!!!
