Improperly sealed bottles - no carbonation

[Delaney]

Hey there,

I recently brewed beer with a friend who was lacking a bit of tricep strength. Long story short, she didn't use enough muscle and ~50% of the bottles didn't carbonate due to improper sealing of the caps. How would one normally tackle this problem? I don't want to empty the beers because I fear I will oxidize them substantially by doing so.

Thanks for the input.

Cheers,

Delaney.

How large are the bottles?
What sugar do you use for priming?

Make a new priming solution and put the proper amount in each bottle using a syringe.

I sense you are suggesting that I may not have waited long enough, which is definitely not the case. The bottles are 355ml, used sucrose for priming. It is 100% due to the seal, because the non-screw bottles from this batch are well carbonated. I used a stand-up capper which I normally have no issue with for either screw or non-screw bottles, but clearly the screw-cap bottles require a little more force which my friend did not apply.

So, back to my question. What is the best way to salvage the uncarbonated beer?

All right, so for 2.3 vol CO2 you need 2.1g sucrose per bottle (I assumed 22C as the beer temperature for calculation purposes)

Boil some distilled or RO water
Measure 42g of sucrose and add enough water to make 100mL. Mix well to fully dissolve ... This gives 2.1g per 5mL.
Add 5mL (1 tsp) to each bottle

Check my math

I've messed up before and mis-messured my priming sugar. Just sanitize your bottle tops, pop the cap, and drop in some Carbonation Drops and re-cap and wait.

PS, don't use screw on cap bottles for this reason.

Cheers, thanks everyone!
