Thanks for the input guys. Had a really smooth go making a SMaSH last night to give the homegrown Nugget hops a test run. Also, it is the first time I used campden tabs and a swamp cooler to control fermentation temps. I've got ferm temp sitting perfectly at 60* whereas previous beers sat with an ambient temp of 72* or higher. I also took the hot wort outside last night in a water bath and got it chilled to 60* real fast before pitching the yeast! Again, previously I was never able to chill it that low before pitching. I hope these are big steps in making a better beer.
It is now 9 hours later and there is no visible activity in the airlock. I am not really concerned yet, I hope to see some action by the time I get home from work later but it is the first time US05 has not kicked it into high gear overnight for me. The one concern I do have though, is that I messed up my recipe slightly... I had made the recipe on Brewersfriend with 6 pounds of DME... I did this because I was sure that is what I had at home. It wasn't until I was in full swing that I realized I only had 5 pounds. That being said, the recipe predicted 1.054 OG and in actuality I ended up at 1.042. Is this going to have a negative effect on the final product, or will it simply mean a lower ABV?
