Source Grain

Stop buying blind. Registered buyers get grain with the numbers attached — protein to the tenth of a percent, on every lot, before the mash is designed.

If you brew gluten-free commercially, you already know the two problems this registry exists to solve: grain that is genuinely hard to find, and grain that arrives without the numbers that decide how to brew it. Registration addresses both at once.

What registering gets you

• Characterized lots. Sellers in this registry commit, under the Lot Reporting Standard, to report protein to the nearest 0.1% and their remaining certificate values on every batch — not on request, not on the good lots, every batch. You see the numbers before you commit the grain to a recipe.
• A documented gluten claim. Lot identity per Gate 1 and gluten status per the truly gluten-free standard — the certificates your own batch records need, arriving with the shipment instead of chased after it.
• Your demand, counted. Gluten-free grain supply is thin because demand has never been visible in one place. Every registered buyer makes the case stronger for malthouses deciding whether to run gluten-free grain at all. Registering helps bring the supply you want into existence.

What we look for in a buyer

This registry is built on both sides holding standards. From buyers, that means:

• Real volumes, stated honestly. A 5-gallon pilot and a 30-barrel production run are both welcome — what matters is that sellers can plan against what you tell us.
• Receiving discipline. The reported values only protect you if someone reads them. Buyers who verify lot identity and file the certificates get the full value of the standard; Batch Records and Ingredient Proof shows what that looks like.
• A gluten-free claim you intend to defend. This chain exists for brewers whose label is a promise, not a marketing position.
