A few weeks ago I brewed a chocolate stout (very small batch) I don't have the recipe to hand but it was two weeks in the fermenter and two weeks bottle conditioned - and primed the gallon with 1 oz of corn sugar before bottling. Two weeks ago I shared some with family (unrefrigerated) and it was fine. Last night I took a bottle from the fridge and opened it and the stout seemed to be very over carbonated and formed a very thick head in the glass as I was pouring it. I put the bottle down and the beer continued to rise out of the bottle. The beer tasted OK. What are the likely causes of this gushing (if that is the right word)?
