I recently brewed my first all grain beer. Had a few hang ups. I didn't get any rice hulls for the mash, I had a stuck mash, yeah that was fun. Once I finally got everything under control I got about 6 gallons for my boil, was hoping for 6.5. When my boil was done I had 4.5 gallons left. My OG was 1.062. The recipe called for 1.050 to 10.57. My question is, after the boil should I have topped of my fermentor with water to get 5gal to bring the gravity down? Kind of like you would for an extract brew.
