Malting Basics
Malt quality is determined before the grain reaches the brewery. By the time it arrives, the enzymatic capacity is fixed. There is no way to improve it during mashing.
Malting is not a pre-processing step you can skip or substitute without consequences. It builds the enzymatic capacity a grain needs to convert its own starch into fermentable sugar. Understanding how that capacity develops — and what can go wrong — is the starting point for everything else in gluten-free brewing.
| Stage | Duration | Goal | Sorghum-Specific Notes |
|---|---|---|---|
| Steeping | 16–24 hours | Raise grain moisture to 42–45% | Slower water uptake, hull adhesion |
| Germination | 4–6 days | Develop enzymes, modify endosperm | Longer window, different growth |
| Kilning | 16–24 hours | Stop germination, dry to ≤5% moisture | Lower temp to preserve enzymes |
Why It Matters for Gluten-Free Brewing:
Sorghum malting is not just a substitute for barley. The process parameters, enzyme development, and flavor outcomes are different. Getting it right is critical for quality, efficiency, and flavor in gluten-free beer.
- Malting is only about flavor. (Reality: It’s about enzyme development and starch conversion.)
- Barley malting rules apply to sorghum. (Reality: Sorghum requires different timing, temperature, and handling.)
