I just brewed a recipe for a biggish beer that calls for 6.6 lbs of light LME and 2.75 lbs of light DME. Given that I always mess up at least one thing when I brew, I measured out 2.75 lbs of DME and 2.75 lbs of LME. I got everything else right - the hops, specialty grains, other fermentables, etc. My only mistake was using 40% of the LME I was supposed to.
The target gravity was around 1.075 but I ended up at 1.049. Adjusting the recipe to account for my mistake, the adjusted target gravity is about 1.050, so it's OK in that regard.
My expectation for the beer is that it will taste great and will taste like I expect it to, but it will be a little lighter in color, have less alcohol, and a little less body. I'm OK with that. Is there anything else that will be off based on the mistake I made?
