I've made the NB oatmeal stout AG recipe 5 times. It's lighter than my preference @1.045+/- but I always had head retention problems, behaved like soda pop. However, the scale of the recipe contains .5 pounds of crystal, .5 pounds chocolate. I posted on here some time ago about my head retention problems and someone suggested adding some flaked barley. Haven't had the chance to make another one just yet, but will give it a try. Something to consider.
