What happens to cask beer if it blows the keystone out during second fermentation?


There are ways and means of replacing keystones in the horizontal position, however if it blows out and you have managed to up-end it without losing too much beer. You can replace the keystone if you have a spare or use the existing one if it isn’t damaged. Roll the container to disperse the finings and re-stillage as normal and let the container clear down, then fingers crossed you will have saved your ale.
