Hi All, I found these... JustYit 24 PCS Silicone Bottle Caps Colorful Bottle Stopper Reusable Rubber Beer Caps Saver Bottle Caps for Home Brewing Beer Kitchen Gadgets, 6 Colors : Amazon.co.uk: Home & Kitchen
It blew the lid off a year or two back the first time i brewed it,
not this brew I have not had the lid off and took great care as usual sanitising, nothing growing on top but it is a bit strange and a worry,
but good idea I will do a SG check if its still bubbling tomorrow.
This proves your point Bez,
I started a Wilko Wheat beer I've had till best before date has run out and thought get it used up before it way long out of date,
I started it on the 8th of July and due to brewing it before and it blowing the lid off the fermenting bucket twice I set up a blow off...
