Over filled bottles?

[Tob]

Hi all, first post from me. I have a question I couldn't find any information on via search.

I've recently started home brewing and had good success so far. Around a month ago I bottled a brew and filled the bottles to very close to the top (within 1-2cm) figuring I could get away with using less bottles (pretty stupid reason in hindsight).

My question is, could this cause the bottles to explode? At the time this didn't occur to me but I've since been told that it's best to leave a bit more air in the top of the bottle to absorb the pressure, as air will compress but liquid won't. The beer is around 5 weeks in the bottle and there have been no signs of abnormal pressure so far, however it is the end of winter here and temperatures will rise over the next few months which I guess means some of the CO2 absorbed into the liquid will change to gas again.

Thanks for reading!

Hi TOB, if you let the fermentation run to completion and you didn't over-prime, 99% chance your bottles will be fine. If you're still concerned, you might put the bottles in the fridge (if you have room).

When my brew assistant and I bottle, we use a bottling wand and let the beer come to near the top of the bottle. Pull the bottling wand out of the bottle, the liquid is at just the right level. No fuss, no worries.

Hi Jim thanks for your reply! The beer is well carbonated and I don't believe there is any significant amount of fermentable sugar left in the bottles, I'm mostly concerned about the temperature change. I can probably fit most of the remaining glass bottles in the fridge so I might do that to be safe. I have about half of it in plastic bottles so they should be fairly safe outside the fridge. I'll use the wand method next time.

Cheers,
Tob
