Snap Posted August 14, 2019 Share Posted August 14, 2019 Having issues with new Cooper Bottles & caps not sealing when bottling Brew ? I take off the bottom ring of the caps to ensure a good seal as I have always done but I am finding my bottles not keeping the gas inside :-( I renewed our bottles after 4 years because the old ones had done a lot of work. Very disappointed to say the least. Lost about 30 bottles last brew :-( out of 190. 1 Link to comment Share on other sites More sharing options...
Micci Posted August 15, 2019 Share Posted August 15, 2019 The way I see it. How the caps are designed. There's no seal inside the cap, but a sealing ring. Twist the cap until you feel some resistance. Then twist it a bit more. This way it will seat the sealing ring properly over the bottle's mouth.

GingerNuts81 Posted August 15, 2019 Share Posted August 15, 2019 I use a 3 stage process. Immediately after filling each bottle, I do the lid firm. After filling all bottles, go through them, and nip them up. Then as I place them in the cupboard to condition, double check to ensure all is tight. I also ensure that the order is different for each stage. 2 Link to comment Share on other sites More sharing options...
Malter White Posted August 17, 2019 Share Posted August 17, 2019 As Shamus wrote, tighten with a tea towel. This not only gives you a firm grip but saves you a few callouses. I've only suffered the occasional soft bottle but when I have I disposed of the cap because it's the most likely culprit of the failure. Also, I only remove the old rings if I'm using a brand new cap because it has it's own ring but with a ring or no ring probably wouldn't make any difference to your seal anyway. Good luck with future bottles. 1 Link to comment Share on other sites More sharing options...
Shamus O'Sean Posted August 17, 2019 Share Posted August 17, 2019 The caps start grinding off the fingerprints from my office worker fingers after tightening four or so caps. Hence the use of a teatowel. +1 to @MUZZY's other comments 3 Link to comment Share on other sites More sharing options...

DonPolo Posted August 22, 2019 Share Posted August 22, 2019 Tea towel saved me more than once. Made the mistake of bare hands a couple of times. Never again! Was numb between forefinger and thumb for days. 1 Link to comment Share on other sites More sharing options...
