My beer has too much carbonation. What is wrong?
This is most likely caused by bottling before the ferment has finished. If the over carbonated beer tastes good, pour it into a pitcher first to let the excess gas escape before pouring it into a glass. In the future, always take two hydrometer readings 4 days apart to determine if the beer has finished fermenting, assuming the temperature is warm enough for the type of yeast you are using. Take the first one after 12 days of fermentation, and the second 4 days later. If the second reading is lower than the first, take another reading until you get two that are the same.
