Hi guys,
Been lurking around for a while, and have seen a lot of great info about brew house efficiency, but haven't seen how to address the problem I'm having with my setup so sorry if it's been asked a thousand times.
I do BIAB, got about four 5-gallon batches under my belt, and am getting great efficiency dunk-sparging (at least 80-85%). I only have a 7 gallon brew kettle atm, so often I "top up" with a gallon of boiled water at the end.
My question pertains to ratios involving specialty malts, in order to achieve desired color, is there a way for me to calculate/factor in the added water, yet still hit my efficiency?
For example; brewed Yooper's Oatmeal Stout 2 weeks ago, brew day went great and I really wanted to get 6 gallons into my fermentor to get 5.25 gallons of beer to package. Took gravity readings throughout the boil and saw that I could top up and still hit 1.052 (the OG for that recipe), so I did. This, however, lightened the color considerably, yet my OG was precisely on point.
How would I have calculated how much more dark grains to use? Does beer smith do these kinds of adjustments? Also, does it pertain to others such as crystal malts, and the base malt will be the thing to adjust for most of the gravity calculation?
I'm currently just using the free online calculators, I know they probably aren't as accurate.
