Brew day was a bit of a disaster. Kind of disappointing since these are some of my favorite hops. I'm concerned that with such a low mash temperature (I was shooting for 153) and the amount of dextrose I put in the beer, I might end up with something too thin for the hop bill. If that's the case, I'm mulling over adding some maltodextrin to the hop tea for body. Ideas?

Yeah, the beer will probably end up on the dry side mashing @ 145 plus the added dextrose. That said malto-dextrin would be a good fix, add it to taste to give it back some body. Good luck, sounds like a great recipe otherwise.
