so after much too-ing and fro-ing on how to do it, what volumes etc - decided to just get stuck in and have a go.
So, stove top BIAB no.1 has been done and I have learnt LOADS!!!
Grain bill:
1.5kg Maris Otter
200gms rolled oats
Mashed at 67C in 5L water for 60mins in a pillow case
Mash out / sparged with 3L water at 80C (basically dunked the pillow case in and out for 5 mins)
Note 1 - pillow case retains too much water. It was a nightmare getting all the liquor out, resulted in twisting, squeezing and all sorts of shenanigans until i finally got 7.5L of preboil wort in my pan.
Note 2 - the grain swells up a bit more than i thought and my pan with the sparge water wasnt big enough to properly dunk my pillow case. I reckon using a proper muslin bag will work much better.
Rolling boil
Hop bill:
7gms Challenger @50 mins
10gms Challenger @10 mins
Final volume of 5L and crash cooled in the kitchen sink filled with ice water.
When the temp settled to 30C i took a reading - OG of 1080!!!
Note 3 - i didnt want an 8% abv beer so i always intended to dilute it slightly to hit my desired OG. but this was way above what i expected when i punched the numbers in to brewersfriend calc.
Diluted it to an OG of 1055 resulting in just short of 8L. Split it between two demijohns and added an Safale-04 starter that had been happily bubbling away for a few hours.
Now lets wait and see what happens!
Note 4 - when i put my actual numbers in to bewersfriend, it says with a boil size of 7.5 and batch size of 5l, to get an OG of 1080 my efficiency was 75%!
really really surprised at that.
As far as IBU and SRM are concerned, how does diluting it affect the numbers? Do i just punch in my final batch size volume and take it as true, or how does that work? But with those ingredients etc, i should have an IBU of 23 and SRM of 5.5
No idea if that good bad or ugly...........
