Pet Bottle Blast Off

[Tony M]

I started a 1098 yeast last year , waited until it looked totally inactive then split into six stubbies. They did not burst but every bottle gushed empty when I opened them. A very messy brew bench. Thank baccus for the packet of Safale on standby.

I split mine into 600 ml pets and release the pressure every so often.

Good practice is to transfer wort at high krausen to your stubbies for that type of storage.... then cover with foil (acts as a primitive airlock) until fermented out. The beer is going to continue to ferment anyway even if capped and refrigerated

By doing this you:
-purge the stubbie of O2 and replace with CO2 from the fermentation
-finish fermentation in a better environment/temp thus stressing it less
-not create any more bottle bombs.



A side note. The reason the starter stubbies explode so catastrophically is because there is a lot more compressed gas in an empty stubbie than the headspace of a full beer..

Seems not all PET bottles are created equal.....
One on the left is a Coopers one from coles. The other from a decent HB shop...
The Coopers one is about 1/2 the weight!
