Today I brewed an Octoberfest using DeathBrewer's Partial Mash tutorial. I made the recipe from Brewmaster Warehouse's recipe builder and everything was to style. The OG was supposed to be between 1.050-1.057. When I took the hydrometer reading it was at 1.066. I made sure when I topped off with water I mixed the hell out of it. So I know it was mixed good enough. What should I expect from this? Will the beer just end up having more alcohol?
