Title: How to set up equipment profile for partial boil?
Post by: frankvw on November 08, 2019, 07:08:40 AM
I'm doing a series of "stove top" partial boil recipes. The idea is to brew 20L batches (20L going into the fermenter) using a 8 liter pot. Yes, I know, there are other ways to do this, but for a variety of reasons this is what I'm doing. :)

The problem is how to set up BS3 (especially the equipment profile) correctly for this method. Several posts have already asked questions on how to deal with partial boils, and I have read them, but they don't really get me to where I need to be.

In a nutshell, what I'm doing is:


How do I get BS3 to calculate (or at least approximate) colour, bitterness and gravity for this mess? :)  Setting up an equipment profile will let me add 2L of water at the end of the boil, but if I do that I will get much less hop utilization than adding 1 liter of boiling water halfway through the boil because the boil gravity doesn't get up as high as when I only top up at the end of the boil. Then there's the diminished hop utilization due to the lower boil volume (which can be significant, trust me).

All suggestions appreciated!
