Call me crazy, but I've been DREAMING of a citrusy tropical stout lately! I must've been brewing without enough ventilation last weekend
Please do keep use (me?) posted. I think this recipe looks intriguing (not to mention the pineapple!) and would like to know how it comes out!
@ maltodextrin, it helps lend thickness in mouthfeel. So if you feel that it came out too thin, You can add 1/2 or even 1 lb of Maltodextrin (just boil in water, cool, and add in secondary, or even at bottling/kegging) to help "oomph" it back up. It's not exactly the same as mashing high, but it can help "patch up" a beer that comes out too thin.
