I have been brewing exclusively all-grain batches for about 12 years now. I am very methodical and OCD about my processes, have all the little toys and instruments and hit my gravity marks and temperature goals easily.
In 50+ batches, all of my beers have come out almost exactly as I had intended (thanks mostly to all of the incredible knowledge and experience the people on this forum have contributed).
I just brewed my first batch using a pump to recirculate my mash. It was an APA I have brewed several times before and all tools and procedures were identical in the process other than the recirculation of the mash (for the full 60 minutes).
The resulting wort looks WAY darker than it should (1/2lb crystal 60 and 1/2lb crystal 20 were used with ~9lbs of pale 2-row - total volume 6 gallons). I have to believe beyond any doubt that this is a 'RIMS-effect'. I have searched and searched, but there is hardly any information about this phenomenon. Obviously, there are several ways to minimize this effect - using less crystal malt or moving from 60L/20L to all 20L (or all 10L) would be my first remedy to this, but ...
Can anyone confirm this 'RIMS-effect' and shed some 'light' on the subject? Has anyone else had a similar realization when brewing with mash recirculation techniques?
Thanks for any conversation,
