Maybe just add honey to the glass before you pour a beer and let it dissolve? Don't tell your friends. Just bring in some pints of beer already poured lol.
I have backsweetened graff using cherry/white grape juice. I just dumped it in the keg. After carbing it up and finding it to be too tart. I doubt if there is much fermentation going on at my serving temp of 38 degrees, everything is crystal clear.
