No carbonation because of missing head space in bottle
Hi guys, new-ish brewer here.
I just finished an APA a few weeks back and thought I was slick when I filled the bottles all the way up to the top to avoid oxidation from the head space. However this has just meant that the beer is lacking carbonation.
Would there be anything preventing me from opening the bottles, remove a bit of beer, add sugar and re-cap them?
Should I add the same amount of sugar as I did at first or less?
