Brewed a 5gal basic wheat. Fermented and carboyed as usual. Per most forums I researched, I added 4 packs of unsweetened Kool aid and the regular amount of bottling sugar after 2 weeks, and bottled. Tried one 2 weeks later. Beer looks and smells like a lemon shandy, but has a very tart lemon flavour. Carbonation was perfect. Question is, how can I sweeten up the other 46 bottles, lol. If I uncapped and add a sugar cube to each, I'm afraid I may make beer bombs. Any advise from the experienced would be appreciated!
