My carb level in the bottles became so much more uniform using the Domino sugar cube trick - simple to prime, and if you over/under shoot your bottle count it's not a big deal.
One of the best secrets for small batch brewing I learned on here...
I was curious so I worked up the math on this. Domino's spec is 2.29 grams per cube.
Volume 0.09375 (12 oz)
Temp at Packaging 68 F
CO2 in Beer 0.8614872 Vol
Table Sugar 2.287 g
Target CO2 2.51 Vol
You are basically packing for 2.5 vols of CO2, which is appropriate for many styles of beer, but may be a little high/low for some (namely low for German wheat beers, and high for English ales).
