MitchBastard Posted February 18, 2019 Share Posted February 18, 2019 Currently got a batch half in glass half in PET. The pet bottles have shown a lot more carbonation at a quicker rate. same cleaning routine, same sanitising routine, same storage conditions also Cold crashed 5 days. I do make a point of filling 3 or so pet bottles first to clear some gunk through and then the same again at the end once she’s getting shallow. ???

Otto Von Blotto Posted February 18, 2019 Share Posted February 18, 2019 I'm just gonna assume you've poured a beer from each type of bottle to test the carbonation level. I have heard reports of bottles with more sediment carbonating either quicker or to a higher level than bottles with a normal sediment level. I can understand quicker due to there being more yeast but getting more carbonation doesn't make much sense to me. It doesn't matter how much yeast there is, it will still only ferment the available sugar present. Link to comment Share on other sites More sharing options...

Definitely. I sometimes bottle a batch in both 750ml and 1.5litre PETs - the larger bottles harden up much quicker. Link to comment Share on other sites More sharing options...

In my mind I Was leaning toward the more yeast thing but as you say it’s still the same amount of sugar? Link to comment Share on other sites More sharing options...

Yes, but if there is more yeast it would likely ferment the sugar faster than if there was less yeast. It doesn't necessarily mean that the beer will be any fizzier by the time they're all fully done though. They should all end up the same eventually.
