I've just realised why my beer doesnt fully carbonate in keg.
I've been trying to carbonate in keg. I lookup the right amount of priming sugar to achieve 2.5vols eg. Add to the whole batch in secondary, then keg half and bottle the rest.
The bottles are carbed perfectly. The kegs maybe land at 1.5 vols and taste a little sweet. So it's not fully fermenting out.
Then it dawns on me; I am transfering to keg carefully so as not to oxengenate, and the purging the headspace and laying CO2 on it.
Of course it won't ferment out! theres almost not oxygen for the yeast to work with!
I am now trying to remedy this by using a (air filtered) beer stone down the liquid line, to dissolve oxygen into the beer so it will ferment out the residual priming sugars.
Of course it still won't reach desired C02 vol (as i have blown it all out while airating) and rather than add more sugar, force carbing the rest with guess work.
In future, I could either airate on transfer to the keg, and seal with CO2, or just transfer to keg, not purge and let the headspace in the keg feed the yeast.
What do you guys do?
