Swing top bottle max carbonation

[MrN]

I've got a hefeweizen fermenting currently and when it's ready am planning to bottle it in some 500ml swing tops I have. As is appropriate for the style I'm planing a level of carbonation higher than what I've attempted before, probably 2.8-3.

I'm a little worried about creating bottle bombs so what's the highest level you've bottle carbonated a beer to? Any words of warning?

Yes, if the bottles explode use less priming sugar.

Seriously, those bottles are nice and thick so the top would leak first. Don't worry so much - drink more beer if necessary.

I use a level measuring teaspoon of table sugar in a 500ml swing bottle, carbonation is pretty good at that level, i go with that whether it's lager/ale/cider, stout i use 3/4 teaspoon.

For Wheat beer i use a heaped teaspoon. Gets a good pop with a swingtop.

Assume they are empty beer bottles or new ones and not the cheap swingtops available in some places,ie IKEA Tesco etc!

Yes they are brown ones specifically for homebrew.

I know I probably don't need to worry but still interested how far people have pushed their bottles it the past!

With the proper homebrew ones you will have a beer that empties itself instantly upon opening well before you get a bottle bomb. I've noticed that a lot of commerical wheat beer bottles are amongst the thinnest.

Yes, this is true. My last year's Xmas beer needed to be re-bottled as it shot out, as described!

Wait, how did you rebottle it if they were all gushers?

if worried just ensure you sit them in waterproof boxes with a towel draped over then during the 2ndary fermentation/conditioning while the pressure is potentially at its maximum due to the heat needed for the yeast activity. post conditioning you can chill and store at serving temps to reduce the risks considerably.

fwiw i have had a few ex-grolsh bottles fail with pressure as a consequence of stoopidly sealing after pouring in an oxi solution to clean off dried on yeast sediment.. the failure was a non explosive crack of glass resulting in a mess only..
