Hey all, this is my first post. I have just reached the fermentation stage of my first brew (NW style IPA) and am confused about what to put in the efficiency section of my recipe. For the recipe I steeped 1 pound of grain for 30 minutes (at 160-170 degrees). I then added 7 pounds of malt extract and 1 pound of dry (both light). I noticed modifying this number made a difference in OG, ABV and bitterness. How am I supposed to figure out what percent to put in this section? Do I just modify until the OG section reading is the same as my actual OG reading when using hydrometer? Any help you could provide this "rookie" homebrewer would be appreciated.
