mini keg help

[col222]

yesterday i just prime with sugar into the mini keg and today found the pressure bung must have blown off , will i need to prime again ?

If the bung has popped out, then either you overprimed, or the gravity was still too high, or the conditioning temperature was too high.

my advice would be to reseal asap and leave for 2 weeks, then cool slightly and enjoy.
