Hi there, I've just bottled my next batch of strawberry Cider and upon trying to cap these I've smashed around 3 bottles in the process (not particularly crimping that hard) and on most of them I can hear just a slight hissing noise from the cap. I'm using the young's double handed capper with wilko gold caps and tesco red caps.. (the gold seem to go on better? ) with Carlsberg export and standard carlsberg bottles.. has anybody else had this problem? Could it just be a mixture of crap caps and or crap bottles..? Ta
