Why

There are two separate questions hiding in this one search, and most pages answer only the first.

Huy Fong, the green-cap rooster bottle. The published ingredient list is chili, sugar, salt, garlic, distilled vinegar, potassium sorbate and sodium bisulfite as preservatives, and xanthan gum, with a "Contains Sulphite" warning. There is no gluten grain in it, and the thickener is xanthan gum, the gluten-free alternative to a flour-based thickener, which is precisely why this sauce avoids the problem that catches other condiments.

The company's position is on its own site: Huy Fong's allergen statement is that its products are gluten-free according to its suppliers. That is a manufacturer statement, and it is what carries the Huy Fong row, but it covers Huy Fong's bottles only, not the category this page answers for, and the wording deserves reading honestly. It is a supplier survey, not a test result and not a certification. There is no GFCO seal on the bottle, and Gluten Free Watchdog, a subscription screening service, catalogues Huy Fong products under "not labeled gluten-free," quoting that same supplier-based wording. The company also reserves the right to change specifications and asks buyers to request current documents.

Other brands are genuinely different products. This is where the category answer diverges from the brand answer:

Where wheat actually enters a sriracha. Not through chillies, and not through vinegar. It enters when a manufacturer uses conventional soy sauce or soybean paste, both brewed with wheat.

Two brands make the same design choice and land in opposite places, which is the clearest way to see the split:

• Kikkoman lists soy sauce on its sriracha panel and is still GFCO-certified gluten-free, because the soy sauce is the wheat-free kind: water, soybeans, salt and sugar, no wheat, brewed as gluten-free tamari.
• Flying Goose Sriracha Black Pepper lists soy sauce too, and its published panel spells the sub-ingredients out: "SOY sauce (SOYbean, WHEAT flour, salt, water, sugar), water, sugar, garlic, black pepper 8.5%, salt, modified tapioca starch, SESAME oil…". Wheat flour is in the first ingredient. That bottle is not gluten-free, and it is sold in the same livery, on the same shelf section, as the brand's Original, which is chilli, sugar, salt and garlic and has no gluten grain in it at all.

This is the single most important thing on the page, because Flying Goose's own marketing tells you the opposite. Its gluten-free page states: "You can rest assured that our Srirachas sauce has always been and will continue to be gluten-free," and "All our varieties offer the same gluten-free, natural qualities as our original Sriracha sauce." The company's own published ingredient lists contradict that blanket claim for the soy-sauce- and soybean-paste-based flavours. Where a brand's marketing page and its ingredient panel disagree, the panel wins.

Read the panel for the words "soy sauce" or "soybean paste," then check whether wheat is declared inside the bracket.

The second entry route is hydrolysed vegetable or wheat protein, used as a savoury booster in some cheaper sauces. Same rule: it would be declared.

How much risk is this?

Celiac disease: Huy Fong is very likely fine and is used routinely by people on a strict gluten-free diet. If you want a bottle with a stronger claim behind it, buy Kikkoman's certified gluten-free sriracha or Lee Kum Kee's labelled one. Both are on the same shelf and cost about the same. The step up from "supplier-surveyed" to "certified" costs you nothing here, which is a rare situation. What you cannot do is buy on the brand name: the one sriracha this page can name as containing wheat, Flying Goose Sriracha Black Pepper, comes from a company whose website says its sriracha is gluten-free.

Non-celiac gluten sensitivity: any mainstream sriracha is fine.

Wheat allergy: the panel is the answer. Wheat must be declared on a US label, and no version of Huy Fong Sriracha declares it. Watch imported bottles, where labelling standards vary.

Cross-contact: Huy Fong makes hot sauces and essentially nothing else, which narrows the plausible contaminants considerably. The facility is not dedicated gluten-free and the company does not claim it is.

The flavoured variants are where a range breaks. Flying Goose alone sells more than thirty sriracha flavours, and the ones built on a savoury base (black pepper, and the soybean-paste styles), are the ones that pick up wheat. If the bottle says anything other than plain sriracha on the front, read the panel.

The derivatives are the other trap. Sriracha mayo, sriracha ranch, sriracha aioli, sriracha seasoning, sriracha-flavoured snacks and instant noodles are formulated products that happen to contain sriracha. They are a completely separate check, and several of them are exactly the sort of thing that carries wheat-based soy sauce or a flour-thickened base.

What to have instead

If you want a bottle you never have to think about:

Related questions

Is Huy Fong sriracha certified gluten-free? No. There is no third-party certification and no gluten-free claim printed on the bottle. The company's allergen statement says its products are gluten-free according to its suppliers, which is a manufacturer statement rather than a tested one.

Is Huy Fong chili garlic sauce or sambal oelek gluten-free? Same company, same supplier-based statement, same absence of a printed gluten-free claim, the screening service Gluten Free Watchdog lists the chili garlic sauce under "not labeled gluten-free." The ingredient lists are similarly short.

Is Flying Goose sriracha gluten-free? The plain ones are. The Original is 61% chilli plus sugar, salt, garlic and water. But the brand's blanket claim that "all our varieties" are gluten-free does not survive its own ingredient lists: Sriracha Black Pepper is built on soy sauce containing wheat flour. Buy Flying Goose by the variety, not by the brand.

Which sriracha should I avoid? The only one this page can name outright is Flying Goose Sriracha Black Pepper. More usefully, avoid the pattern: any sriracha whose panel opens with soy sauce or soybean paste rather than chilli, unless wheat-free is stated inside the bracket.

Is sriracha mayo gluten-free? Separate question, separate answer. It is a mayonnaise product with sriracha in it, and the other components matter. Read the panel, or make it yourself: any gluten-free mayo plus sriracha.

Is soy sauce gluten-free? Standard brewed soy sauce is not. It is made with wheat. Tamari is the traditionally wheat-free style, and Kikkoman brews a certified gluten-free soy sauce using rice in place of wheat.

Is gochujang gluten-free? Often not. Wheat flour is a common ingredient in commercial gochujang. Certified gluten-free versions exist and are clearly marked; assume nothing from the category.

Does the xanthan gum matter? No. Xanthan gum is produced by bacterial fermentation of a sugar and is gluten-free. Its presence is mildly reassuring, since a sauce using xanthan gum is not using flour.

How we checked

Overall source tier: A, verdict depends. Documentation differs by brand: Huy Fong's gluten statement rests on a supplier survey rather than a test, and Lee Kum Kee's server refuses automated fetches, so that row rests on a manual check. Flying Goose advertises its whole range as gluten-free while its own panel puts wheat flour in Sriracha Black Pepper, and that finding rests on a label, not a gluten statement. No celiac organisation has ruled on sriracha, so use the brand rows above, not the category answer, when you are holding a bottle.

Last verified: 10 August 2026. Formulations and allergen statements change, Kikkoman's own sriracha recipe was revised to use gluten-free tamari. The bottle in your hand outranks this page.
