Title: Converting All Grain to Partial Mash
Post by: bendbrew on January 25, 2010, 10:19:42 am
Does anyone have a calculator for converting all grain recipes to partial mash?  I am doing the partial mash system written about by Chris Colby in the October 2006 issue of BYO.  I have a two gallon cooler I converted into a mini-mash ton.  I think the most it can handle is 4lbs or so of grain.

Thanks,

Bill

Hard to beat Beersmith, but I used the HBD recipator for a long time when I did partial mash.  Here is the link http://hbd.org/cgi-bin/recipator/recipator

What I used to do is calculate my grain bill based onthe max size mash I could handle, and then figure out how much DME or LME to add to get to my OG.  Although I do all-grain now, I made some of my best beers as partial mash.

I have used the same 2 gallon cooler method with 4 pounds of grain for years.  Works great. 
I've never seen a need for going all grain.

Here is the best description I've read on recipe conversion.  It came from 1998 AHA comvention.

+eleventy billion to Ken's stuff.  That's where I learned to do partial mash and build a tun from a cooler.  His other work on batch sparging is what got me headed down that road.
