Brewed 8/20
Secondary 8/29
Ferment at 63 degrees
Split the whirlpool hops; adding half at flameout. The other half once down to 165F.
Dry Hop in Two stages - 4 days each, split the dry hops in half also. Add the first half to primary. Stage one 8/29. Short .5 centennial, switching 1.0, increasing Apollo by .5.
10 day fermentation (63-64F at first, then ramp up to 68-70F once fermenation slows.
8 day, 2 stage dryhop in primary at 68-70F.
Rack to secondary and 4 day cold condition in the secondary at roughly 39F (basically refrigeration).
Force carb and drink 3-4 days later, or bottle and drink 1.5 to 2 weeks after priming.

So I took the brewery worksheet figures (referenced with the red circle), scaled them down, and plugged it into Greg Noonan's Vermont Pub & Brewery's Water Witch: https://byo.com/resources/brewwater
As you can see, the layout of this calculator looks incredibly similar to the snapshot of the brew sheet.
Here are the results for 6 gallons: (Keep in mind, the Alchemist reportedly uses "Plaster of Paris" instead of Gypsum. Also, homebrewer lactic acid is typically 88% strength vs. the 85% version shown here).
________________
I supplied two different results (in color). Notice the difference when using Calcium Sulfate Anhydrous (Plaster of Paris) vs. Calcium Sulfate Dihydrate (Gypsum) that must be used to hit 750 mg/L.
The information when whittled down, lines up... 6 gallons, approx. 21.6 grams plaster of paris, 1.2, grams calcium chloride, and then adjust mash pH to 5.1-5.3 with lactic acid.
