Non Dedicated Maltsters and Suppliers
As existing and new malting operators look to enter the gluten free market, there are a number of things that those maltsters, their distributors, and brewers need to have in mind when evaluating the food safety for consumers with medical reasons to avoid gluten. Theoretically non-dedicated malt houses can safely avoid cross-contamination issues with a combination of proper cleaning protocols (for easier to clean stainless steel surfaces) and dedicated equipment / spaces where appropriate. Maltsters should have detailed standard operating procedures (SOPs) for mitigating risks of cross-contact with gluten containing grains, provide a good degree of transparency around these SOPs, and be willing to have their practices reviewed by external parties.
At present there are no shared facility malt houses that have been certified by a gluten free inspection body (e.g. GFCO) or gluten free brewing industry panel.
Key considerations for utilizing malts from non dedicated sources:
- GF grain sourcing (grower practices, harvesting and shipping) -- GF grains are frequently grown in rotation with non-GF crops
- Intake process and storage bins (are grains inspected for presence of gluten containing grains at receiving, are they stored in dedicated containers?)
- Conveyors and handling between tanks, floors, rooms
- Dust management (kiln ventilation can blow barley dust throughout the malthouse)
- Water (can sometimes be recycled between steeping vessels)
- Packaging equipment
- Deculmers and other equipment that is hard to clean can be sources of contamination
Skagit Valley Malting - Non-dedicated malt house, Washington (US)
- Began offering pale millet malt and buckwheat malt in 2020.
Haus Malts - - Non-dedicated malt house, Ohio (US)
- Malts oats, millet, sorghum, and corn.
Colorado Malting Company (CMC) - Non-dedicated malt house, Colorado (US)
- Malts red and white proso-millet, buckwheat, and sunflower seeds.
- Risks may be mitigated by having an "isolated" facility for the gluten free malts.
- Retail sales for CMC are handled by Boulder Fermentation Supply. There is a higher risk of cross contamination at this facility that repackages gluten free malts for homebrewers alongside their gluten-containing products, and Zero Tolerance members have found barley grains in their gluten free CMC grain orders in the past.[1]
Sugar Creek Malt Co - Non-dedicated malt house, Indiana (US)
- Lists a small number of limited release malts including corn, rice, buckwheat, pumpkin seeds, sunflower seeds, and acorns. They are primarily maltsters of barley, wheat and rye, and make no claims around gluten free products or handling. The likelihood of cross contamination for the gluten free grains is high.
La Malterie des Volcans - Non-dedicated malt house, Saint-Germain-Lembron (France)
- Lists millet and buckwheat malts alongside gluten containing grains. No claims around gluten free products or handling. Without further information, assume that the likelihood of cross contamination for the millet and buckwheat grains is high.

Sorghum and Rice Syrup
Briess is the main manufacturer of gluten free sorghum syrup (aka sorghum extract) and rice syrup. These ingredients are relatively easy to find in local home brew supply stores (LHBS) in North America and Australia, but may require more effort to track down elsewhere. In the UK, Briess sorghum extract can be purchased via Hamstead Homebrew. Briess advises that their products are available through CMG (Country Malt Group) with international distribution partners in South and Central America, UK, Ireland, and Asia. If they don't currently carry those products, you can request to bring them in. See the CMG Locations and Sales Team page for contact information.
