I brewed a pumpkin porter and the recipe had maltodextrin in it. I missed the step and added it at the end of the boil for about 10 minutes....will my porter be messed up or bad now?
It's fine. It's an adjuct for body and mouthfeel, and can be added anytime in the boil...or can be added even along with the priming sugar if you forget, or added into the primary or secondary as long as you boiled it up to sanitize it.
