Yeah, I guess I did that. The original recipe did not say to add a liter of water, instead it says to add the 2 oz of coffee (dry) in the secondary. You could take that liter out of your original water measurement, or boil off a bit more, since you know you'll be adding back a little water, or you could add 2 oz of coffee to the secondary. There are probably lots of ways to add coffee, try one and see how it goes, then post back.
