the guyser beer is caused from a over carbination. to much priming sugar added, orrr. another aspect can be a high gravity than expected when the the priming sugar is added. which means that while you added the correct amount of primings... you actually doubled it.

this is where a home brewer must use a hydrometer. it will measure your gravity. sometimes the gravity is still to high within the ale. if you have a slow or sluggish fermintaition, you will end up with a higher than expected gravity. which in the final stages of everything.... causes what?

GUYSER BEER!...

if this occures. be sure open the remaining bottles in a very cold state. this will in keeping the C02 from bursting from the solution.
