I am looking to brew Northern Brewer's Grapefruit Pulpin' and have plugged the recipe into Beersmith. In order to match the OG they claim in the recipe (1.065) with their grain bill I had to set it at 62% efficiency. I have 80% efficiency so obviously I need to scale it to my system to get a new grain bill. I scaled this to my equipment with two methods and it isn't making sense to me the outcome I am getting.
Here is the original recipe at 63% efficiency.
13 lb Rahr 2-row (94.55%)
8 oz Dingemans Cara 20 (3.64%)
4 oz Briess Caramel 20L (1.82%)
When I scale this to my 80% efficiency system checking the box "keep original color and IBU's, I get this grain bill:
9 lbs 13.7 oz Rahr 2-row (90.54%)
11 oz Dingemans Cara 20 (6.31%)
5.5 oz Briess Caramel 20L (3.15%)
To me it makes no sense at all that for the same volume, reducing the amount of 2-row makes you need to increase the amount of crystal malts to keep the color. Tome this would change the entire taste of the beer wouldn't it?
Now let's say I don't check that box and I just opt to scale to efficiency only. I get a grain bill where the ratios stay the same but the color is below 5 SRM compares to 6.3 SRM.
What is the correct and best way to scale this? Do I want the ratio of grains to stay the same for taste or the color, why can't I have both? It is driving me crazy, I just want the final product to be the same as the original and the only difference is efficiency. Is there some kind of wrong calculation Beersmith is using?
