How to Fix Exploding Beer Bottles (3 Steps)

Exploding beer bottles are also known as "Bottle Bombs" and they are the byproduct of bad brewing. Bottle bombs are usually caused by over-carbonating your home-brew and -- if left undetected -- the bottle can physically self-destruct in a dangerous explosion of glass and bottle caps. The key to fixing and avoiding beer bombs is to add the right amount of priming sugar before bottling.

Instructions

  1. Prevent exploding beer bottles by adding the right amount of priming sugar when bottling. Brewers usually add dextrose -- corn sugar -- when bottling to carbonate the beer, but if you add too much of it the beer will be over-primed and the carbonation of the brew will escalate. If the beer carbonates too much, the gas will need to escape the bottle -- this will cause an explosion. Add enough sugar at the bottling stage to match the amount of beer you are brewing -- a good rule of thumb is to add 3 oz. of sugar for every 5-gallon batch.

  2. Bottle the beer in bottles that are designed for carbonation. Bottles that are safe for carbonation have a thick glass body; avoid using ones with twist-off caps because they are too thin and the caps will not properly seal. Also avoid using bottles with a capacity greater than 1 liter.

  3. Store your beer in a dark and cool place. Light and heat will cause the beer to ferment further and increase the CO2 pressure in the bottle; heat will also increase the pressure of the bottle itself.
