Thanks for your feedback. It would be interesting to hear of whatever you learn. As I think about it, my FG was 1.010, lower than the 1.017 FG estimated in the recipe. That could explain the difference malt character of my outcome. While the brew is very enjoyable, it does not have the awesome balance between sweet maltiness and hops. It's just another hoppy IIPA, which is not an entirely bad thing. I cannot determine if the variation is a process error on my part, or a result of the 149 deg. mash. I would be interested in the FG of others that were more successful with the outcome. In any case, I ordered a bunch more Thomas Fawcett Amber Malt and going to try and get this clone nailed.
