Somewhat new to all grain and I just finished my HERMS system based on The Pols setup. For my first brew in this system I have decided to do a simple Kolsch and would like to make sure I am calculating efficiency correctly.
Here is what I have for the recipe.
Recipe Type: All Grain
Yeast: WLP029
Yeast Starter: 1000mL
Batch Size (Gallons): 5.5
Original Gravity: 1.047
Final Gravity: 1.005
IBU: 30.4
Boiling Time (Minutes): 60
Color: 4.5
Amount Item Type % or IBU
9.00 lb Pale Malt (2 Row) US (2.0 SRM) Grain 87.8 %
1.00 lb Munich Malt (9.0 SRM) Grain 9.8 %
0.25 lb Wheat Malt, Ger (2.0 SRM) Grain 2.4 %
2.00 oz Tettnang [3.50%] (60 min) Hops 28.5 IBU
0.50 oz Tettnang [3.50%] (15 min) Hops 1.9 IBU
The person who put the recipe together says he is at 70% efficiency, but this system will likely be much higher. I am not sure how much wort I am going to start the boil with so I am not sure how to calculate the efficiency I should have before the boil.
Here is my guess. (6 gallons to start in the BK???)
Pale 38x 9/ 6 = 57
Munich 35x1/ 6 = 5.8
Wheat 37x.25 / 6 = 1.5
Total = 64.3 ppg
So I should theoretically have an OG of 1.064 if I was at 100% efficiency, correct? The part I am not sure on is how to calculate the initial boil volume to figure this out. I guess I need help figuring out how much initial strike water and sparge water to start with and then how much initial wort I should have collected for the boil.
I believe this person adjusted their grain bill to reflect the 70% eff as well. Does this mean that if I purchased the same amount of grain and my eff is higher, my brew is going to be off?
Confused, Scott...
