Help a poor guy scale a recipe.
« on: March 18, 2014, 04:59:54 pm »
I'm brewing the Gaelic Ale (Highland Brewing) clone recipe from BYO's 250 classic clone book. I'm having to scale my recipe to a 3 gallon batch for my equipment. Best I figure, they are basing the recipes on a 70% efficiency where as I get around 75%. Essentially I am reducing all amounts using the  Brewmate software from 5 gal to 3 gal and then adjusting my base grain to match the intended OG for the recipe based on my all grain efficiency. My problem is, no matter what I do... 5 gallon, 3 gallon, base grain adjustment... it doesn't matter, I keep getting an SRM of around 15. The recipe says I should be in the 24 range. I made sure all of my lovibond settings match the intended grains but it is still coming in a bit pale. Should I just brew it or am I missing something.

Thanks for any suggestions.

I don't have that book. Post the grain bill and specs.

Recipe as it appears in book
5-gal batch
OG 1.056
FG 1.014
IBU 32
SRM 24
ABV 5.6%

7.6 pounds briess pale malt
2.75 pounds briess 10L munich
1 pound crystal 40
.5 pound crystal 60
.25 pound briess extra special

My version scaled using Brewmate:
3 gallon batch
OG 1.059
FG 1.015
SRM 16
Assuming my 75% efficiency
mash @ 150 single infusion 60 min
90 minute boil

3.6 pounds Briess pale malt (using pale ale)
1.7 pounds Briess 10L munich
.6 pounds crystal 40
.3 pounds crystal 60
.15 pounds Briess extra special

I'm assuming they are using a lower efficiency cause I had to reduce my base grain a bit to get the OG right but this didn't seem to affect the SRM value. I just feel like I'm missing something. I don't have this problem when I scale recipes from Brewing Classic Styles but this one is baffling me a bit.

Could be a typo. A quick google search netted a few recipes with similar grain bills. One noted 16 srm as the color.

Yeah. I think I'll just brew it and worry about the color later. Thanks for the help.
