Popped open one of my bottles of Graybeard Nut Brown Ale this evening to check the carbonation. It gushed all over the table, a foamy brown fountain. Yes, it was carbonating very well, thank you.
I stuck another bottle in the fridge. Now I’m going to put it in the sink and pop the top and see what happens…
The brown foam slowly climbed out of the bottle and ran down the side. Perfectly manageable. I should be able to take some of these to class for evaluation.
