I’d give it another week. Try gently inverting the bottles (don’t shake), and let them settle out for a week. It’s possible your priming sugar wasn’t distributed evenly and you got an underprimed bottle. I’ve only added yeast after bottling once. Rehydrate dry yeast and add a drop or two with a sanitized eye dropper to each bottle. Recap with new caps. You don’t want to add more sugar. A bit more patience might be all you need, though. Mike
5 days in the bottle is not enough to carb them. Wait 2 weeks, 3 weeks is better, try one. If not carbed, wait another week. Make sure they’re at room temperature to carb.
Five days is way too soon to expect carbonation. I may get antsy at ten days but I know 14 days is the best. I have 4 cases carbing now, 12 days in the bottle. I’ll probably chill a couple tomorrow for Monday.
I had a beer of each the past 2 days. 1 at 13 days, and 1 at 14 days. carbonation was okay, satisfactory but the beer just does not taste as it should. Another week and it will be aged better. It will be mo better.
