How sure are you that fermentation is finished before you bottle? Not priming and getting bottle gushers makes me think fermentation is still not finished and you're getting the oldest ones gushing. If it's a random 20% of bottles then I'd say it's a bottle cleaning issue.Bertie Doe wrote: ↑Tue Feb 02, 2021 3:36 pmAh thanks, the present batch I'm drinking - Black Sheep/Nottingham and IPA/West Coast, about 20% of the bottles are fizzers, with a lot of head. I didn't realize that yeast played a part and had assumed that the culprit was the Torrified Wheat, which I use to promote head.
Torrified wheat doesn't really give you more head, it just makes the head you do get more stable.
