4 weeks ago, I brewed a Belgian ale (5 gallon batch) with an OG of 1.051. Two weeks ago, I transferred the beer to a 5 gallon carboy, and the gravity was at 1.027. Yesterday, I checked the gravity, and it was at 1.024. I want the FG to be at around 1.013-1.014. Is this considered a stuck fermentation or a slow fermentation? Is there anything I can do to speed up the process? Thank you!
