Hi everyone. I bottled two batches of beer at the same time. One an amber ale and the other a pumpkin ale. Bottle 2 weeks ago. The amber ale is fully carbonated while the pumpkin is as flat as could be. I have them in the basement where it is a little colder then recommended for conditioning, but if one is done, shouldn't the other? I did a second racking with the pumpkin for over a month. Left the amber ale for only 2 weeks in the primary before bottling. Is yeast settling the issue? What's the fix to this? No Kegging system so carb drops? The amber was a pretty run of the mill beer but the pumpkin was a high octane at 9.9 abv, not sure if that matter.
Appreciate any thoughts you may have,
