I'm an extract brewer. First post to this Forum...
I've had a few brews come out darker than expected, so I'm playing with recipe designs on Beersmith to try to understand the effect of the extract boil time on the outcome - using it like a simulator.
For a simplistic Kolsch, if I add a light LME with a boil time of 0, the bitterness is 20 IBUs, colour 3 SRM.
If I set the boil time to 1 minute the IBUs jump to 27.2, colour 3.
For 5 min I get 26.7
If I then go up in increments of 5 minutes the IBU decreases in a (roughly) straight-line until getting back to 20 IBUs at 60 minutes.
The colour stays constant at 3 SRM.
Intuitively (based on limited experience) I'd expect the colour to increase the longer the Liquid Extract is boiled, and I'd kinda expect the bitterness to do the same. But this is not what Beersmith is telling me.
Is my intuition wrong (in which case I'm keen to be set right!) or could I be missing something in the way I use (or have set up) the software???
