Larry Sayre, Developer of 'Mash Made Easy'
Announcing the release of 'Mash made Easy' version 9.50 in both the USA and Metric formats.
Changes include:
1) Ended the formerly ongoing experiment of attempting to conform Kolbach's observed calcium and magnesium mineral induced downward pH shift within the mash to Taylor's (and visa-versa). Discovered that in the end the difference appears to more closely be one of buffering factor differences between typical German Pilsner malts and typical UK Pale malts. The downward shift due to calcium and/or magnesium itself is highly controversial as to its magnitude within the mash, and the Kolbach Multiplier suffices to allow for compensation spanning most all of the current thinking here. At a value of 1 (the default) it follows Kolbach directly and fully. At a value of 0.5 it mirrors the suggestions of AJ deLange. Or set it fractionally anywhere from 0.25 to 1.00 to help match MME to your local process and its measured and observed mineral induced pH shift.
2) The above removal of the Kolbach/Taylor compensator greatly simplified the means to incorporate the addition of Ca(OH)2 as an optional means to raise pH (in addition to Baking Soda). This allowed for the removal of the complex and cumbersome Ca(OH)2 adjuster I had previously added when I attempted to merge Kolbach and Taylor, thus neatening and simplifying the main pages looks and end user functionality.
As always, Mash Made Easy is both free and complete, and can be downloaded from my website address link as seen in orange below.
