Too much sugar for carbing

BrewNerd

Hi
I have just bottled 17 x 500Ml glass beer bottles of brewferm grand cru. I stupidly got my calculations wrong and added twice the amount of dextrose recommended for carbing. I have now put the bottles in a warm area and put them on top of polythene bags in case they start to pop. I've also put a towel over the top of them.

I am wondering should I do anything else? Maybe recap after a week or so to release some of the gas... Or should I just leave them?

Thanks for any advice...

I'd probably just leave them.

You'll probably be ok and just have very fizzy (and slightly stronger!) beer.

Worst case they will be over pressurised, how much sugar did you add to each 500ml bottle? Just let us know, as you have done keep them somewhere where no damage can occur in the meantime just in case they are over pressurised

Thanks all. I added 126g brewing sugar dissolved in boiling water. Was supposed to be 63g...

BrewNerd

That's 126g mixed into the entire batch. About 8.5 Ltr.

126g for 8.5 litres does sound quite a lot and could potentially over pressurise the bottles, store them out of the way as a precaution and you may think about letting some of the pressure out, it's hard to say with certainty and you never really want to open a brew early unless necessary, but recapping after a week may be a wise precaution. Had the bottles been PET plastic you can feel the pressure and they will also bulge if they start to get too much carbonation, but with glass there is no way of knowing

BrewNerd

OK I think I might recap after one week. I assume I won't need to do anything else other than keep them in a warm place for another two weeks?

HBO_Staff

If you keep them warm for a week this helps the priming sugar to dissolve and secondary ferment to produce the carbonation, then leave for longer - a few degrees cooler can help them clear. The longer you leave them the better as the flavours will develop, ideally keep away from light and for as long as possible

BrewNerd

OK thanks.

Update. I popped the caps after one week, recapped then let them carbonate again for another week and moved to my conditioning place. I did try one just to see if it was still carbonated. It was, if even still a little too much. Now the wait till summer before I try again.
