A beer brewed without gluten-containing grains (barley, wheat, rye, spelt, some oats) — using alternative grains such as sorghum, millet, buckwheat, rice, corn, quinoa, amaranth, or teff. Base style can be any — pale ale, IPA, stout, lager, pilsner — provided the grain bill is gluten-free from the start (dedicated GF) or the gluten is removed/reduced below the required threshold (gluten-reduced). Typically 4–8% ABV, with the specific flavor profile determined by the base style and the alternative grains used.

Origin
Dedicated gluten-free beer is a creation of the 2000s, when growing recognition of celiac disease drove demand for a beer that people who cannot tolerate gluten could safely drink. Because barley, wheat, and rye are off-limits, brewers turned to alternative grains — sorghum first among them, later joined by millet, rice, and buckwheat. Two sorghum beers anchored the category’s commercial arrival. Bard’s, developed by celiac-diagnosed founders who set out to make a beer that actually tasted like beer, billed itself as North America’s first gluten-free beer. In December 2006 Anheuser-Busch launched Redbridge, the first nationally distributed sorghum lager, bringing the idea to a mass audience.
The early beers were often thin and one-dimensional, but the 2010s brought a wave of dedicated gluten-free breweries that treated the constraint as a brewing challenge rather than a compromise. Ghostfish Brewing in Seattle, building its beers on millet, rice, and buckwheat, and Holidaily Brewing in Golden, Colorado, both brew exclusively gluten-free and remain in operation, expanding the range from pale ales and IPAs to stouts and lagers. Running alongside this dedicated category is “gluten-reduced” beer, made from ordinary barley but treated during fermentation with an enzyme that cleaves gluten proteins below the regulatory threshold. Such beers can test as low-gluten, but because the enzyme fragments rather than eliminates the proteins, they are not considered safe for everyone with celiac disease, and the distinction between gluten-free and gluten-reduced remains a meaningful one for sensitive drinkers.
Notes
The most important thing to understand on the shelf is the gap between two similar-sounding labels. “Gluten-free” means the beer is brewed entirely from grains that never contained gluten — sorghum, millet, rice, buckwheat, and the like — and is the designation a celiac drinker can rely on. “Gluten-reduced” (sometimes “crafted to remove gluten”) means the beer was made from ordinary barley and then treated with an enzyme to break the gluten down; it may test below the legal limit, but it is not the same thing and is not considered safe for everyone with celiac disease. Truly gluten-free breweries typically work in dedicated facilities to avoid cross-contamination, and the best of their beers come strikingly close to their barley-based counterparts, though a careful palate can usually still detect the underlying grain.
