Understanding the difference: Gluten-free vs. Gluten-reduced
For many with celiac disease or severe gluten sensitivity, understanding the difference between gluten-free and gluten-reduced products is a critical step in avoiding adverse health reactions. A truly gluten-free product, as defined by the FDA, is completely free of any wheat, rye, or barley ingredients and must test below 20 ppm of gluten. In contrast, a gluten-reduced product begins with gluten-containing ingredients, such as barley, and then undergoes a process to remove or break down the gluten proteins. This is the process Stone Brewing utilizes for its 'Delicious' line of beers. While the gluten levels can fall below the 20 ppm threshold, the fundamental presence of barley means it does not qualify for the 'gluten free' label, and the potential for residual gluten remains.
The process behind Stone Brewing's 'Delicious' series
Stone Brewing has been transparent about its process for creating its 'Delicious' line of beers, which includes popular options like Stone Delicious IPA and Stone Delicious Hazy IPA. The journey begins just like a traditional craft beer, with standard ingredients including malted barley. During the fermentation stage, the brewers add a specific enzyme called Clarex. This enzyme's function is to separate and break down the gluten protein chains, effectively reducing the gluten content in the final product. Stone goes to great lengths to ensure their processes minimize cross-contamination, including rigorous cleaning and sanitizing of all equipment used for the Delicious series.
The risk for those with celiac disease
While Stone's method successfully reduces gluten, it is important to note that the beer is not 100% gluten-free. Traces of gluten may remain, and for individuals with celiac disease, even small amounts of gluten can trigger a severe autoimmune response. This is why the FDA’s labeling regulations exist—to protect sensitive individuals. Some sources suggest that the enzyme process may render the gluten proteins non-reactive for some people, but there is no universal guarantee. Medical professionals generally advise that those with celiac disease err on the side of caution and opt for products that are explicitly certified gluten-free.
Comparison: Stone's Gluten-reduced vs. Certified Gluten-free Beers
| Feature | Stone's Gluten-Reduced ('Delicious' Series) | Certified Gluten-Free Beers |
|---|---|---|
| Ingredients | Brewed with traditional barley malt. | Brewed with naturally gluten-free grains like sorghum, rice, millet, or buckwheat. |
| Processing | Uses a specialized enzyme (Clarex) to break down and remove gluten proteins. | Does not use gluten-containing grains from the start; avoids cross-contamination. |
| FDA Label | Can only be labeled 'Gluten-Reduced' or 'Crafted to Remove Gluten'. | Can be labeled 'Gluten-Free' (under 20 ppm). |
| Risk for Celiacs | Not recommended due to potential for residual gluten and risk of adverse reactions. | Generally safe for those with celiac disease when cross-contamination is prevented. |
| Taste Profile | Maintains a flavor profile more akin to traditional IPAs, as it uses barley. | Flavors can differ based on the grain used, with a wide variety of styles now available. |
The Verdict: Who is Stone Brewing's 'Delicious' beer for?
Stone's gluten-reduced products are a fantastic option for individuals who have a mild gluten sensitivity or simply wish to reduce their gluten intake without sacrificing the classic taste of a barley-based beer. The use of the Clarex enzyme allows them to achieve a very low gluten level (below 20 ppm) while retaining the traditional flavor profile that is often lost in beers made with alternative grains. However, for those with diagnosed celiac disease or a high level of gluten sensitivity, the risk of a reaction is simply too high, and certified gluten-free options are the safer choice. This provides a welcome middle-ground in the market for many craft beer enthusiasts.
Conclusion
In summary, is Stone Brewing gluten free? No. Are some of their beers gluten-reduced? Yes. The Delicious series from Stone Brewing is crafted to remove gluten using an enzyme, resulting in a product with a gluten level below the FDA's 20 ppm standard for 'gluten free,' though it still originates from barley. This key distinction means it is suitable for some, but not all, who are on a gluten-conscious diet. For individuals with celiac disease, certified gluten-free beers remain the most reliable option for safety. The ultimate choice depends on an individual's specific dietary needs and the severity of their gluten sensitivity.
