Pure instant coffee is naturally gluten-free — only coffee extract and water in the process.
Yes. Pure instant coffee (Folgers Classic Instant, Nescafé Taster’s Choice, Maxwell House Instant, Café Bustelo, Starbucks VIA) is made from brewed coffee dried into crystals — no gluten ingredients. Per Folgers (Smucker), instant coffee contains no gluten. CRITICAL EXCEPTIONS: 3-in-1 instant coffee mixes, instant cappuccino/latte/mocha mixes, and coffee substitutes (Pero, Postum, Cafix — made from barley) are NOT gluten-free.
Instant coffee is one of the easier gluten-free questions — it’s brewed coffee that’s been dried into crystals. No grains, no gluten. The complications come from the adjacent product category: instant cappuccino mixes, 3-in-1 sticks, and coffee substitutes that look like instant coffee on the shelf but contain barley malt or wheat-derived creamer.
Watch Instant Coffee for changes

What’s in Pure Instant Coffee
Per Folgers’ FAQ: Folgers ground and instant coffee are made from 100% pure coffee. Pure coffee — whether ground, whole bean, or instant — contains no wheat, barley, rye, or oats. The manufacturing process is brewed coffee extract dried into crystals (spray-dried or freeze-dried). Per FDA labeling rules, pure coffee is not a gluten-containing grain.

Frequently Asked Questions
Is instant coffee gluten-free?
Yes. Pure instant coffee is gluten-free — it’s brewed coffee dried into crystals, with no other ingredients. Per Folgers (Smucker), no gluten ingredients are used. Major brands including Folgers, Nescafé, Maxwell House, Café Bustelo, and Starbucks VIA are widely treated as gluten-free.
Is Folgers instant coffee gluten-free?
Yes. Folgers Classic Roast Instant and Folgers Coffee Singles are made from 100% pure coffee with no gluten ingredients per Smucker. Folgers does not carry a formal “Gluten Free” label on the jar but the company confirms no gluten ingredients are used.
Is Nescafé gluten-free?
Pure Nescafé Taster’s Choice and Nescafé Gold are gluten-free. Nescafé 3-in-1 mixes (coffee + creamer + sugar in one stick) are NOT reliably gluten-free — the non-dairy creamer in 3-in-1 mixes often contains wheat-derived ingredients. Verify each Nescafé product individually.
Is Starbucks VIA gluten-free?
Standard Starbucks VIA Ready Brew (Italian Roast, Colombia, Pike Place, etc.) is gluten-free — it’s microground coffee plus instant coffee, no gluten ingredients. Starbucks does not formally label VIA “Gluten Free.” Flavored variants and Latte/Mocha mixes should be verified individually.
Are coffee substitutes (Pero, Postum) gluten-free?
No. Pero, Postum, Cafix, and similar “coffee substitute” or “coffee alternative” products are made primarily from roasted barley (and often rye and/or malted barley). Barley is one of the FDA-defined gluten-containing grains, so these products are NOT gluten-free and not safe for celiacs.
Is decaf instant coffee gluten-free?
Yes. Decaffeination uses solvent (methylene chloride or ethyl acetate) or water-process methods, neither of which involves gluten. Decaf instant coffee from major brands (Folgers Decaf Instant, Nescafé Decaf Taster’s Choice) is gluten-free.
