Brew Type: All Grain
Style: Classic American Pilsner
Batch Size: 6.00 gal
Boil Volume: 7.50 gal Boil Time: 90 min
Brewhouse Efficiency: 80.0 %
Ingredients Amount Item Type % or IBU
9 lbs 4.0 oz Pilsner (2 Row) Ger (2.0 SRM) Grain 77.9 %
2 lbs 6.1 oz Corn, Flaked (1.3 SRM) Grain 20.1 %
3.8 oz Acid Malt (3.0 SRM) Grain 2.0 %

Beer Profile Estimated Original Gravity: 1.059 SG (1.044-1.060 SG)
Estimated Final Gravity: 1.015 SG (1.010-1.015 SG)
Estimated Color: 3.7 SRM (3.0-6.0 SRM)
Bitterness: 40.8 IBU (25.0-40.0 IBU)
Estimated Alcohol by Volume: 5.7 %
Mash Profile
Grain Temperature: 72.0 F Sparge Temperature: 168.0 F
Sparge Water: 6.02 gal Adjust Temp for Equipment: TRUE
Name Description Step Temp Step Time
Step Add 14.84 qt of water at 165.3 F 150.0 F 60 min
I plan on using 90% RO or distilled water plus an addition of CaCl2 to hit approximately this water profile.
Ca ppm 61
Mg ppm 9
Na ppm 2
Cl ppm 64
SO4 ppm 89
Which should give me a mash pH of ~5.3-5.4
I'm going to rehydrate the two dry yeast packets, pitch at ~44F and let rise to 48-50F. Oxygenation for 90 seconds with .5 micron stone. Ferment until close to terminal gravity ~80%, check for diacetyl and perform a rest if necessary.
I'm looking for general feedback or possible suggestions. I'm a little nervous even with s-23's rehydration temperature being in the mid to low 70's that it might not reach a low enough temp to cold pitch. There's also the matter of how the adjunct will change the mash pH, I've heard that corn and rice have significantly lower buffering capacity.
