Sorry mate, as you can tell, I get a bit lost with what I'm posting and to whom sometimes, and I deal with a few different calculators :lol: With the priming calculator, its the amount of beer that is available to bottle once off the trub....so what I do is, I have all my cubes that I will rack to marked with a scale. (hours of fun when buying new cubes, filling them 1 litre at a time and marking off the results
)There are then 2 ways you can do a good accurate prime.
the first is to rack, then add the dex disolved in 1/2-1 cup boiling water. Stirring can be more awkward, but you always get a good true measure. The second is to add the dex disolved in 1/2-1 cup into the bottom of the cube, and then rack onto it. I never do the second way on the odd occasions that I go straight from primary, cos its too hard to judge the losses, and if you put enough priming sugar in for 22L and only end up with 20L, you cant take the sugar out again....but if your going from secondary to prime, its not so bad, as the loss is usually pretty damn small anyway, and can be either discounted or judged pretty accurately.
Now accuracy in the prime isn't necessarily that crucial. It becomes more problematic at the high and low end, ie if aiming for 2vol, if you underprime, it will be flat, and if aiming for 2.9vol, if you overprime, you could get bombs (particularly in glass). If youre aiming for somewhere in the middle, say 2.5vol, you have leeway either way. As long as you're not ridiculously off, slightly under will still have fizz, slightly over won't explode. It's best to aim as close as you can to what you want, though. The only thing worse than a flat APA is an aggressively carbonated Best Bitter. :lol: You'll probably be looking at a likely 2.5 to 2.7 vol for your recipe
