Enzyme Dose Calculator
Scale the Reliable Mash's enzyme and addition doses to your batch.
Enter your sorghum-malt weight and the calculator scales the documented per-pound additions and the cooling and dilution water. It answers how much of each addition your batch needs. It is a planning aid for the working baseline, so validate the result on your own malt and equipment.
| Addition | When | Basis | Your batch |
|---|---|---|---|
| Initial water | Mash-in | ≈ 1.4 qt/lb | 140 qt35 gal |
| Rice hulls | Mash-out (when bed behavior is uncertain) | ≈ 5% of malt weight | 5 lb |
| Termamyl SC DS | 190°F (88°C) — liquefaction, at mash-in | 1 mL/lb (V12 sheet; corrected from the pilot's 2 mL/lb on 2026-09-07) | 100 mL |
| Ondea Pro | 145°F (63°C) — conversion | 1.5 mL/lb | 150 mL |
| Termamyl SC DS (2nd dose) | 145°F (63°C) — conversion | 0.75 mL/lb | 75 mL |
| Amylase AG 300L | 145°F (63°C) — finishing | 0.75 mL/lb | 75 mL |
Scales the documented per-pound basis of The Reliable Mash to your grain bill. It is a starting point to validate on your own malt, water, and equipment — not a universal recommendation. Cooling/dilution water is calculated separately (add only what reaches 145°F), and pH 5.5–5.6 and ≈ 100 ppm calcium are targets set against your source water, not quantities that scale with grain weight. Record the actual product, dose, and lot for every addition.
