3 min read

While many assume hard seltzers are gluten-free, some products, including Hard MTN DEW, are not. Hard MTN DEW, despite being mistaken for a true hard seltzer, is actually a flavored malt beverage and contains gluten, making it unsafe for individuals with celiac disease or gluten sensitivity.

Quick Summary

Hard MTN DEW is a flavored malt beverage, not a traditional seltzer, and contains gluten due to its brewing process similar to beer, making it unsuitable for a gluten-free diet. This guide explores the difference between Hard MTN DEW and true hard seltzers, explaining why one is safe and the other is not. It covers ingredients, brewing methods, and safe alternatives for those with gluten sensitivities.

Key Points

  • Hard MTN DEW Contains Gluten: Hard MTN DEW is a flavored malt beverage, not a hard seltzer, and is brewed with malted grains, which makes it contain gluten.

  • Not Safe for Celiacs: Due to its gluten content, Hard MTN DEW is not a safe beverage option for individuals with celiac disease or gluten sensitivity.

  • Original Mountain Dew is Gluten-Free: The non-alcoholic version of Mountain Dew and its variants are generally considered gluten-free and do not pose a risk.

  • Difference in Base Ingredients: True hard seltzers are made by fermenting cane sugar or other gluten-free bases, whereas Hard MTN DEW uses a malt base.

  • Marketing is Misleading: Hard MTN DEW is often shelved with hard seltzers, so careful label reading is necessary to avoid confusion.

  • Always Check the Label: The classification 'Flavored Malt Beverage' is a key indicator that a product likely contains gluten.

Understanding Hard MTN DEW vs. Hard Seltzer

Many consumers hear the term "hard seltzer" and assume all beverages in that category are automatically gluten-free. This assumption can be a dangerous one for those with celiac disease or gluten sensitivity. The key distinction lies in the base alcohol used in the beverage.

Why Hard MTN DEW is Not a Seltzer

Hard MTN DEW is officially classified as a flavored malt beverage (FMB). This is a crucial detail for anyone following a gluten-free diet. Unlike many popular hard seltzers that use a fermented cane sugar base, FMBs like Hard MTN DEW use a brewing process similar to beer, starting with malted grains. Because the product is brewed with grains that contain gluten, the final product retains gluten, making it unsafe. The manufacturers, Boston Beer Company, explicitly state that all Hard MTN DEW products contain gluten.

The Brewing Process: Malt vs. Sugar

The production method is the primary reason for the gluten content difference between Hard MTN DEW and true hard seltzers. A traditional hard seltzer is made by fermenting a sugar base, typically cane sugar, which is naturally gluten-free. The resulting alcohol base is then filtered to be clear and flavorless, acting as a blank canvas for fruit flavorings. In contrast, a flavored malt beverage uses malted grains, and while flavoring is added later, the gluten from the malt remains.

The Problem with Mislabeling and Assumptions

The marketing and consumer perception of 'hard seltzer' can be misleading. Many products, like Hard MTN DEW, are marketed alongside true hard seltzers and positioned as a competitor, but are chemically and functionally different due to their base ingredients. For someone relying on brand recognition, grabbing a 'hard MTN DEW' from the seltzer aisle without checking the fine print could result in accidentally consuming gluten.

Safe Alternatives to Hard MTN DEW

For those seeking a truly gluten-free alcoholic beverage with a fizzy, flavored profile, there are many options available. Consumers should look for products that specifically state they are "gluten-free" and have a fermentable sugar base (like cane sugar), not a malt base. Some popular gluten-free hard seltzer brands include Truly, White Claw, and Bon & Viv. There are also many gluten-free beers available on the market made with alternative grains like sorghum or millet.

The Importance of Label Reading

For individuals with celiac disease, vigilance is key. Always read the ingredients list and look for explicit "gluten-free" labeling on the packaging. When a product is described as a "flavored malt beverage," it is a red flag indicating the likely presence of gluten.

Comparison Table: Hard MTN DEW vs. True Hard Seltzer

Gluten-Free Status of Regular Mountain Dew

For clarification, it's worth noting the status of non-alcoholic Mountain Dew. Most regular soft drinks, including standard Mountain Dew varieties, are considered gluten-free. The ingredients in soda are typically carbonated water, high fructose corn syrup, and flavorings, none of which contain gluten. This is completely separate from the alcoholic Hard MTN DEW version, which has a different ingredient and manufacturing process.

Conclusion: Read the Fine Print

In summary, the assumption that all "hard seltzers" are gluten-free is false, and Hard MTN DEW is a clear example of why. Because Hard MTN DEW is a flavored malt beverage brewed from malted grains, it contains gluten and is not safe for a gluten-free diet. The original, non-alcoholic Mountain Dew is gluten-free, but consumers must be cautious when choosing the alcoholic version. Always check the label for the "flavored malt beverage" classification or a clear gluten-free certification to ensure safety. For those with celiac disease or gluten sensitivity, it is essential to distinguish between true hard seltzers with a sugar base and FMBs to avoid accidental gluten consumption.
