I have an upcoming birthday so I decided to brew a Bday beer for myself. After kicking around different ideas I figured I should brew something that is popular but with a twist for me so I settled on an American IPA but a boatload of Mosaic hops late. I also decided to make this my first Caramel/Crystal free IPA since it seems there is a general move away from these malts in IPAs on the West Coast. Why not give it a whirl! I recently moved so my eBIAB system is out of commission till I get an electrician scheduled so I brewed this on my old 3 vessel system. Here is the recipe:

thoughts: fantastic beer. nice and dry but not minerally. this much mosaic may be a bit much. probably better mixed with other hops. that said, they are delicious hops with a whole lot going on. fantastic beer. big fan of the grain bill and caramel malt is not missed.
