Spursman Posted December 13, 2019 Share Posted December 13, 2019 I started having a few bottles whose caps were either splitting around the perimeter or cracking in the centre. This naturally led to no carbonation and wasting the brew. Wondered if I was overtightening the bottles but my brew shop owner said not possible. Checked brews again yesterday and found 9 bottles affected. Went back to brew shop with some of the faulty tops and the owner confirmed that there is a faulty batch of caps in circulation . Replaced the brew mix and carb drops no charge. 3 Link to comment Share on other sites More sharing options...

You've essentially got free beer! Link to comment Share on other sites More sharing options...
Lab Cat Posted December 14, 2019 Share Posted December 14, 2019 That's the way to build and keep customers. One free kit and some bits is a lot smarter than having an argument about who's fault it might be. Link to comment Share on other sites More sharing options...

You should 'Name and Fame' the LHBS - sounds like you've got a good one so a little promo couldn't hurt him. 2 Link to comment Share on other sites More sharing options...
Red devil 44 Posted December 14, 2019 Share Posted December 14, 2019 I don’t bottle much as I keg, but I punted all my PET bottles & replaced them with Grolsch Style flip top largies, much better IMO 1 Link to comment Share on other sites More sharing options...

I did that, a Toucan stout which I don't normally do in plastic because I keep it for a year or more. Reprimed it sat on the laundry floor for a couple of months, maintained pressure with same cap. I was reluctant to drink it but it was fine and I still haven't got my Darwin award. It is a good virtually free way to check a suspect cap/bottle and you can salvage the beer. 1 Link to comment Share on other sites More sharing options...

I did try that with one carb drop but it produced a White Island type eruption and beer all over the floor! not impressed so abandoned that idea. Is there a way to re prime without the eruption. Don't know if it makes any difference but I keep my carb drops in the fridge ( it's a Qld thing). Link to comment Share on other sites More sharing options...

Is there a way to re prime without the eruption. Work faster! It'd probably help to chill the beer first, though I've had to re-prime on the odd occasion and managed to get it done before there was any violent release of CO2. Sounds like in your case there was still a a fair amount of CO2 dissolved in the beer. Link to comment Share on other sites More sharing options...
Southern Man Posted December 14, 2019 Share Posted December 14, 2019 I am in the process of going to kegs and have a lot of PET bottles (including 30 new) and amber glass bottles available for free. I am on the Central Coast near Woy Woy. Pick up only. Link to comment Share on other sites More sharing options...
Spursman Posted December 15, 2019 Author Share Posted December 15, 2019 (edited) So i took the advice about too much co2 causing an eruption when I added a carb drop. Didn't chill the existing brew but poured into a large jug from a height to release the co2. Added a carb drop to the bottle and (after a while) poured the brew back in. No eruption. Thanks to Blacksands for the advice.. Fingers crossed now! Edited December 15, 2019 by Spursman Incomplete Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted December 15, 2019 Share Posted December 15, 2019 Hopefully the oxygen that would have introduced doesn't cause any issues. Link to comment Share on other sites More sharing options...

Pretty new to this so didn't know that was a potential problem. Do you recommend a different method for re-priming low/no carb brews? Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted December 15, 2019 Share Posted December 15, 2019 Anything that avoids splashing the beer really. Chilling them down before opening and re priming would probably be a better method. Just let them warm up again afterwards obviously. Link to comment Share on other sites More sharing options...
