too much priming sugar

[sorefingers23]

i bottled a batch or guiness clone 2 weeks ago and the recipe called for 2.3 volumes of priming sugar, and i just realized that i put 2.6 volumes, is this something i should worry about?

How much sugar did you use for how much volume of beer?

 

[sorefingers23]

142g of priming sugar for 21 liters of beer at a room temp of 64.5

You fermented the entire time at 64.5? Thats very precise! I have trouble keeping in a "range" from 62-65.

But anyway, your priming sugar amount is fine.

No no that was the temp of the room I keep my bottles, that's the numbers I put into beersmith, the 64.5 is cuz I converted from 18 Celsius and that's what I got. So I shouldn't expect to be getting gushing bottles?

Oh, you don't use the room temperature that you're keeping the bottles at in the calculator! You use fermentation temperature, or the highest temperature the beer reached. That's because the calculator is taking into account residual co2 that is dissolved in the beer. If the beer fermented at 50 degrees, for example, it would have far more c02 in it than a beer fermented at 70 degrees. Since the co2 off-gasses in the fermenter, you use the highest temperature the beer reached either at or after fermentation.

Those calculators don't explain that, and that's why I find them pretty useless.

Regardless, if you used 142g of priming sugar in a 21L batch and it was an ale, you're fine.

Yoop beat me to it. You should be fine. I don't know how long it took me to figure out the temperature in beer smith was the ferment temp, not the bottle storage temp. Any how, it will work just fine, and now hopefully you figured out something much quicker than many of us, thanks to HBT!
