Grain Sourcing Overview
Grain sourcing is not shopping. It is the first quality decision in a gluten-free beer.
The brewery inherits whatever the grain supplier did right or wrong. Source, cultivar, crop year, storage, cleaning, transport, documentation, and gluten-free handling all become brewing variables.
That matters more in gluten-free brewing because the grain is carrying two jobs: it has to make good beer, and it has to support a claim people rely on.
What Sourcing Has To Answer
| Question | Why It Matters |
|---|---|
| What exact grain or product is this? | Species, form, cultivar, malt type, extract type, and processing history affect the beer. |
| Who handled it? | Supplier, processor, maltster, storage site, and carrier all affect risk. |
| Was the gluten-free path controlled? | Shared equipment, weak cleanout, or vague segregation can compromise the lot before brewing starts. |
| Can the lot be traced? | The brewery needs the physical material, COA, shipment, storage, and batch record to line up. |
| Does the lot fit the process? | A grain can be gluten-free and still be wrong for the mash, malt target, or beer style. |
| What changed since last time? | Crop year, storage age, supplier process, facility, or product spec changes can change performance. |

Practical Takeaway
Do not let the purchase order be the first quality gate. A serious gluten-free grain program qualifies the supplier, defines the lot, controls the handling path, and keeps enough records to explain the beer later.
