I plan to do my first BIAB next weekend. Because it's my first, and I don't know what my efficiency will be, I've planned it as a partial mash so I can calculate the right amount of extract I need at the end to hit my target O.G.. I think I have my recipe and everything planned out pretty well the way I want it but I could use some help estimating my water volumes.
I have a standard 7.5 gallon turkey fryer set up. I usually start with 6 gallons when doing an extract brew/steeping grain recipe and finish after a 60 min boil with about 5 gallons. I don't really have any idea though how much water my grain (8.5 lb.) will soak up, how much will be lost to evaporation, or even how much I'll be able to fit in my pot once all that grain is in there. Plus I've read Rye Malt and Rice hulls tend to soak up even more so that complicates it even more for me. I was hoping someone with experience with BIAB could look at this and give me some advice. How much water should I start with? How much would I expect to loose in the mash? How much would I expect to have to add before the boil? Ideally I'd like to end up transferring about 5 gallons to the primary.
If it helps, here is my malt list.
4.50 lb. US 2-Row Malt
1.50 lb. US Rye Malt
0.75 lb. German CaraMunich II
0.75 lb. US Caramel 40L Malt
0.25 lb. US Carapils Malt
0.25 lb. US Caramel 120L Malt
0.25 lb. Belgian Aromatic Malt
0.25 lb. US Rice Hulls
2.00 lb. Extract - Light Dried Malt Extract
Thanks a ton.
