Had a boo boo with Imperial Stout kit

I made the NB extract Imperial Stout kit the other day. I just realized after looking over the instructions again that I added the whole 12 lbs of LME at beginning of boil. 6 lbs should have been a late addition at 15 minutes left in the boil.

Is this going to effect the final product?


Not really. There might be a slight increase in kettle carmelization of the wort, which may increase your final gravity and darken the beer slightly. But it’s an imperial stout, it’s going to be heavy and dark anyways. I doubt you’ll notice a difference.
