Announcing the release of 'Mash Made Easy' version 10.85

[Silver_Is_Money]

With due apology for the recent rash of rapid fire revisions, as often happens when I get an idea, and try to best offer it to my users, a light finally went off in my head which greatly simplified the task of targeting a desired 'Knockout pH' with a single acid or base addition (most likely acid) to be made within the Mash, as is the most familiar and common and comfortable place to make the pH adjustment. The choice to adjust the Mash pH lower so as to hit a targeted ideal 'Knockout pH' is optional, and left up to the user. The user can either target the Mash pH they have always preferred, and then (optionally) use the 'Kettle pH' sheet/tab whereby to hit a desired 'Knockout pH', or enter the suggested Mash pH derived from the 'Knockout pH' calculator into their Mash pH Target cell and make pH adjustment a one shot deal (as opposed to a two shot deal). The choice is yours. And with this said:

'Mash Made Easy' version 10.85 is now available for free download on my website in both USA and fully Metric versions.

Changes made since the last release:
--------------------------------------------------
1) Removed the now redundant 'Knockout pH' tab/sheet module.
2) Replaced it with a calculator on the main 'Mash pH' tab/sheet which computes the Mash pH target most likely to result in achieving ones targeted 'Knockout pH'.

The instructions for this optional method are as follows:
A) Enter your desired Knockout pH (pH post boil and cooling) into the yellow user input cell to the right of "Desired Target Knockout (Post Boil And Cooling) =" calculator.
b) Manually enter this calculators output as seen at the right of the "Mash pH Target To Set To Achieve The Knockout Target =" cell into the "Desired Target Mash pH @ 68 F." (or 20 C. for Metric) cell.

Here is the full method whereby to properly compute in advance either a single 'Knockout' added acid addition, or a double acid addition (with one addition whereby to hit the Mash pH Target, and a second addition whereby to hit the Knockout pH target) within Mash Made Easy version 10.85:

First, we must realize that Kolbach's work in establishing pH shift due to Ca and Mg was measured at and oriented toward Knockout, and scientists like Barth and Zaman and AJ deLange tried to retrofit Kolbach's equations to the Mash. AJ often claimed that in his direct observation the drop in pH witnessed during the Mash due exclusively to Ca and Mg ions present within the mash water was on the order of only 50% to 60% of Kolbach's observation at Knockout. To achieve 50% to 60% of Kolbach (as per AJ) within MME during the Mash requires setting the "Kolbach Ca++ and Mg++ pH Shift Multiplier" switch/cell to 0.50 or 0.60 respectively. I have this switch/cell set to 0.50 when you download MME, which means MME is in the Mash pH calculation mode when you download it.

And second, we must realize that for Knockout computations of pH adjustment the "Kolbach Ca++ and Mg++ pH Shift Multiplier" switch/cell within MME must be set to 1.00 whereby to match the observations of Kolbach.

With this information in hand, we are now ready to proceed to the following step by step instructions:

A) Direct Knockout single pH adjustment addition:
-------------------------------------------------------------------
1) Set the ""Kolbach Ca++ and Mg++ pH Shift Multiplier" switch/cell to 1.00 (Knockout pH mode)
2) Set the "Desired Target Knockout pH (Post Boil And Cooling) =" calculator to your desired Knockout pH (lets say 5.20). For the example of choosing a 'Knockout Target' of 5.2 pH the suggested Mash pH is computed to be 5.32, as will be observed directly below.
3) Set the "Desired Target Mash pH @ 68 F. =" (or @ 20 Deg C. for Metric) cell to the calculated 5.32
4) Add the resulting pH adjustment as a single addition to be made with 10 minutes remaining within the boil.

B) Double pH adjustment additions, with one addition made within the Mash whereby to hit your Mash pH target, followed by a second addition made within the boil whereby to hit your Knockout pH target:
----------------------------------------------------------------------------------------------------------------------------------------------
1) Follow all of the steps as seen above for 'A', and record the addition for a single 'Knockout pH' targeting addition for use later (in step 5 below).
2) Set the "Kolbach Ca++ and Mg++ pH Shift Multiplier" switch/cell to 0.50 (Mash pH mode)
3) Set the "Desired Target Mash pH @ 68 F. =" (or '@ 20 Deg C. =' for Metric) cell to your desired Mash pH target (I prefer setting this to 5.50, but you may use whatever mash pH target satisfies you)
4) Add the MME calculated adjustment to your mash water. Then mash.
5) Subtract your calculated Mash pH adjustment (from step 3, as added in step 4) from your calculated knockout pH adjustment (from step 1), and add the result of this subtraction (the remaining adjustment) when 10 minutes remain within the boil whereby to hit your desired Knockout pH (pH post boil and cooling) target.

NOTE: The above instructions for double additions (mash and boil) are valid only for the case of double acid additions. If your mash requires baking soda or Ca(OH)2, set MME to mash pH mode and make only a single baking soda or Ca(OH)2 addition within the mash. Then use the "Kettle pH" module whereby to compute your acid addition to be made with 10 minutes remaining in the boil.
