Welcome / How to Use This Site
This is not barley brewing with different grain names pasted into the recipe. Gluten-free grains behave differently, and so does their malt. Starch access, external-enzyme strategy, runoff, flavor development, and quality control all have to be designed around the ingredients actually in the brewhouse.
That system is what this site explains — and the promise underneath every page is simple: we publish what is known, show what remains uncertain, and invite people to help test, correct, and improve it. The knowledge base explains how to brew; the Research Library holds the data and proposals underneath it, downloadable and citable; and if you find something wrong, telling us makes the site better.
Start With the House Standard
- Truly Gluten-Free: Our Gluten-Free Standard — no wheat, barley, rye, oats, or gluten-reduced workaround.
- Gluten-Reduced Beer Is Not Gluten-Free — why starting with gluten and explaining it away later is a different category.
The Three Ideas That Unlock the Site
Gluten-free brewing needs its own assumptions. Sorghum, millet, rice, corn, and buckwheat are not defective barley. Judging them by how well they impersonate a grain they are not will cost you years.
Malt and conversion have different owners. Malt makes the beer taste like beer. Conversion is a separate problem with a separate solution — the external-enzyme program. Confusing the two is the most expensive mistake in gluten-free process design.
Trust starts upstream. A finished-beer test cannot repair weak sourcing, cross-contact, vague records, or a process that began outside the standard. Testing verifies the system; it does not redeem it.
Choose the Problem You Are Solving
| Reader job | Best starting point | What it gives you |
|---|---|---|
| Understand the gluten-free boundary | Truly Gluten-Free | The governing ingredient and trust standard. |
| Understand why the brewing system changes | Why Gluten-Free Brewing Is Different | The high-level grain, mash, enzyme, runoff, flavor, and QA shift. |
| Choose or understand grain | Gluten-Free Brewing Grains | Grain roles, strengths, limits, and best-fit uses. |
| Understand malt | Malt Matters | Why malt gives beer its soul while external enzymes own conversion. |
| Build or troubleshoot a mash | Brewing Process | Starch access, external enzymes, mash strategy, separation, and fermentation paths. |
| Protect the gluten-free claim | Quality Assurance | Supplier proof, cross-contact control, records, testing, and release logic. |
How to Read the Technical Pages
When a page gives a temperature, an enzyme addition, or a working rule, read the conditions around it as part of the number. Grain source, malt quality, grind, water ratio, equipment, enzyme product, and temperature program can each move the result somewhere you did not intend.
Use the numbers. Do not worship them.
A page here should tell you what an ingredient or process contributes, what it does not, where it fails, what to inspect when it does, and which deeper page owns the full explanation.
What This Site Is Not
It is not neutral. Some approaches work, some are situational, and some waste beer.
It is not medical, legal, or regulatory advice. Use it to understand the brewing and trust issues, then verify the rules that apply where you produce and sell.
And it is not finished. Better records, more experiments, and the occasional hard-earned correction will keep changing it.
