So I'm trying my first all grain tomorrow. Since I still do stove top boiling with my 5 gallon kettle and I want to try a full boil for once, it'll be small batch (about 3.5 gallons when all is said and done). I was able to get a water profile and crunching the numbers through Palmer's Excel Spreadsheet that I got off his website, it says that my water untreated should a bitter beer in the 10-12 L range. BJCP says that's within range, but I see so many recipes nowadays much lighter.
Also, this will be a strange all grain as I don't have a mash tun. The plan is to mash in a cooler, then pour into the kettle with a paint strainer bag to strain the grains. I'm thinking about doing a pour over sparge as well if possible. What do you think my efficiency will be? I'm trying to calculate this in brewtoad and checking the numbers on IBUs and OG.
Let me know what you all think. I could use the advice!
