Grain Fundamentals
Fundamentals · Evaluate grain before process correction
This section defines the major gluten-free brewing grains and the properties that matter most when selecting and processing them.
What To Evaluate First
Start with grain properties first, then map them to process behavior.

| Evaluate First | Why It Matters |
|---|---|
| Starch amount and accessibility | Sets how much fermentable sugar the process can reliably produce |
| Protein level and structure | Influences foam, haze, and mouthfeel stability |
| Lipid content | Higher lipid load can increase oxidation risk and stale flavor over time |
| Kernel hardness and size spread | Drives milling consistency and downstream separation behavior |
| Moisture and storage stability | Controls shelf stability and mold risk before processing |
| Husk or fiber behavior | Affects mash runoff (lauterability), filtration, and solids handling |
Why Fundamentals Matter
If fundamentals are ignored, breweries often try to fix upstream grain mismatch with downstream process tweaks. That usually creates unstable results, slower troubleshooting, and avoidable cost.
