Afternoon folks, I've only done three all grain brews so far, but I've had the same issue twice. I've used the all grain kits from Get-er-brewed. The Citra single hop turned out really really well, but the IPA and a different IPA kit I had done previously were so fizzy that they erupted out of the bottle once they were opened. Process to brew for all: Brewed BIAB following the recipe. Fermented 2 weeks until constant FG Batch primed with sugar (calculated to give 1.5 vols CO2 for all) Bottled Conditioned for 2 weeks In the fridge for 2 weeks Opened Cleaned up! I had wondered whether I hadn't mixed the sugar properly (I add it to a bottling bucket then add the beer on top) but all the bottles seemed the same..... My thoughts so far: Overprimed, not finished fermenting or not mixed the sugar in properly. Any advice would be greatly appreciated. Cheers!
