Hello guys,
I really need some help with this one... I'm all grain, performing batch sparges. I've attached my recipe for your perusal
Here's my problem - I ALWAYS end up with too much water and low pre-boil gravity after sparge. Today, for example (and why I'm writing this post), I did the attached recipe. My boil volume should have been 30.90 liters, however, I wound up with 33 liters instead. My pre-boil OG should have been 1.049 but was 1.040... I'm SO discouraged.
I have lowered my "Batch Efficiency" to 65% in BS, it used to be 70% but I'm trying to get it "closer" to what reality happens to be.
I'm in the process of defining each step of my process; things like getting my exact evap rate (4 liters/hour), batch sparge temp, etc. I'm stuck, however, on why I keep getting more wort than I should when I perform my sparges...
To the best of my ability, I believe that BS uses something like .455 liters of water per pound as the grain absorption rate - but I am getting way less than that.
I perform my own grain crush, Barley Crushed with about .36 +/- on the rollers.
I perform batch sparge: 2 step, both equal size. I add the water, stir for 2 minutes then let it rest for 5 minutes. Perform my vourloff (sp?) and let it drain.
Guys, can anybody help me understand what's going on? Am I really getting a grain absorption rate around .3 liters/pound? Can that be improved?
