I've been lurking around for a while, but I just made a boo-boo, and my need for advice has just motivated me to post!...
I started brewing a batch of Imperial Coffee Stout this weekend. You could call it a partial mash, as I'm taking an "add water and stir" all-grain kit (from the Brew House -- they're in B.C., Canada), but I'm using it as a base to which I'm adding ingredients and mashing. I'm doing all this as per instructions on their web site.
My problem: the recipe called for 1 oz of Norther Brewer hops for a 5 gallon batch. I'm making a 2 gallon batch (so I won't cry as hard if I need to flush it). That should mean 0.4 oz. But somewhere in converting from oz to grams, and copying and printing the recipe, I made a horrible mistake: I added 91 g of hops, which turns out to be 8 times what the recipe asked for (91 g = 3.2 oz !!!!).
Should I just flush the whole thing down the drain now, or is there anything that can be done to fix this? (N.B.: in the name of science, I won't flush it, because I am curious to see what happens to it.) Still, any thoughts of yours would be most appreciated.
One last note: I ended up using Northdown hops, as I couldn't get my hands on Norther Brewer hops. Not that this should make much difference now!
