I have a bunch of leftover pre-crushed specialty grains and partially used hop bags from my last 2 brews and I am trying to formulate a recipe that will use a good amount of them up. I have a lot of dark grains so I decided to try and Imperial Stout, which is one of my favs.
This is my first attempt to formulate a recipe. I looked up a bunch of Imperial Stout recipes and tried to see what are common ingredients and proportions for this style. Again, keep in mind that the recipe is formulated with the primary goal of using up much of what I have on hand, so the quantities may look a little strange.
Some of the questions that I have are: Will this particular the mix of grains complement each other? Do I have the proportions right? What about the hops are they complementary? I'm doing a mini mash - is the mash temp too high (158)? I used BeerSmith so my gravities and IBUs are pretty much in the style. I am just not sure what it will taste like!
Note: this is a 3 gallon batch.
