Mainstream ketchup is gluten-free — tomatoes, sugar, distilled vinegar, and spices, and Heinz confirms it.
Yes. Mainstream ketchup is tomato concentrate, sugar, distilled vinegar, salt, and spices — none of which is a gluten-containing grain. The common worry is the vinegar, but distilled vinegar is gluten-free even when originally distilled from a grain, because distillation removes the gluten protein, and the FDA rule permits it. Heinz states its Tomato and Organic Ketchup are gluten-free; Hunt’s is distilled-vinegar-based (confirm the on-pack statement). The only exception is a few imported “spiced/brown” ketchups that use malt vinegar (barley).
Mainstream ketchup is gluten-free, and it’s worth knowing exactly why, because the one thing people worry about — the vinegar — turns out to be a non-issue. A standard bottle is tomatoes, sugar, distilled vinegar, salt, and spices. None of that is a gluten grain, and distilled vinegar is gluten-free even when it started from grain.
The only genuine exception is a niche one: some imported British or “spiced/brown” sauce-style ketchups use malt vinegar, which is barley. This guide confirms the big brands and flags that exception.
Why Ketchup Is Gluten-Free
Mainstream ketchup is tomato concentrate, a sweetener, distilled vinegar, salt, onion and garlic powder, and spices. Per FDA labeling rules, the gluten-containing grains are wheat, barley, and rye — none of those ketchup ingredients is on the list. The classic question is the vinegar, and the answer is reassuring: distilled vinegar is permitted in gluten-free products because distillation removes the gluten protein, even if the vinegar was originally distilled from a grain. So it is not treated as a gluten-containing-grain ingredient.
Brand confirmation makes this concrete. Heinz states that its Tomato Ketchup and Organic Tomato Ketchup are gluten-free (distilled vinegar base). Hunt’s ketchup is also distilled-vinegar-based with no gluten ingredients; under Conagra’s labeling policy, products validated as gluten-free carry a “gluten-free” statement, so confirm the on-pack claim. Annie’s, Primal Kitchen, Sir Kensington’s, Tessemae’s, and store-brand US ketchups are tomato + distilled or cider vinegar + spices and are gluten-free, many with a GF label.
The real exception is malt vinegar. Some imported British ketchups and “spiced/brown” sauce-style condiments are made with malt vinegar, which is barley-derived and not gluten-free. That’s the one thing to check on a specialty or imported bottle — mainstream US tomato ketchup is safe.
Brand-by-Brand: Which Ketchup Is Gluten-Free?
Mainstream US ketchup is gluten-free; the only watch-out is an imported/specialty malt-vinegar style.

Cross-Contamination Risk
Manufacturing
Low
- Tomato, sugar, distilled vinegar, spices — not a gluten grain.
- Distilled vinegar is gluten-free (distillation removes gluten).
- Heinz states GF; Hunt’s is distilled-vinegar-based.
Specialty / Imported
Medium
- Some “spiced/brown” or imported styles use malt vinegar.
- Malt vinegar is barley — a gluten-containing grain.
- Confirm the vinegar type on specialty styles.
Restaurant
Low
- Bottled ketchup is gluten-free.
- The risk is shared-fryer fries or a shared dip.
- Use a single-serve packet if a communal dip is in use.

- A “gluten-free” claim or stated GF status (Heinz)

- Imported “spiced/brown” sauce-style ketchups, unverified
- Worrying about distilled vinegar (it’s gluten-free)
Frequently Asked Questions
Ketchup is reliably gluten-free, so the questions are mostly about the distilled-vinegar myth and the imported malt-vinegar exception. Here are clear answers.
Is ketchup gluten-free?
Yes. Mainstream ketchup is tomatoes, sugar, distilled vinegar, salt, and spices — none of which is a gluten-containing grain. Major US brands like Heinz are gluten-free.
Is the distilled vinegar in ketchup gluten-free?
Yes. Distilled vinegar is gluten-free even when originally distilled from a grain, because distillation removes the gluten protein. The FDA rule permits distilled vinegar in gluten-free products, so it is not a concern in mainstream ketchup.
Is Heinz ketchup gluten-free?
Yes. Heinz states that its Tomato Ketchup and Organic Tomato Ketchup are gluten-free (distilled vinegar base). Always confirm on the specific bottle, especially for specialty or imported variants.
Is Hunt’s ketchup gluten-free?
Hunt’s Tomato Ketchup is distilled-vinegar-based with no gluten ingredients. Under Conagra’s policy, products validated as gluten-free carry a “gluten-free” statement on the label, so confirm the on-pack claim for full assurance.
Which ketchup is not gluten-free?
Some imported British or “spiced/brown” ketchup and sauce styles use malt vinegar, which is made from barley — a gluten-containing grain — and is not gluten-free. Check the vinegar type on specialty and imported styles.
Is restaurant ketchup gluten-free?
The bottled ketchup itself is gluten-free. The real restaurant risk is the fries it is served with (shared fryer) or a shared communal dip, not the ketchup. A single-serve packet sidesteps the shared-dip issue.
Can people with celiac disease eat ketchup?
Yes. Mainstream tomato ketchup made with distilled vinegar (Heinz, Hunt’s, store brands) is naturally gluten-free and celiac-safe. Avoid malt-vinegar “spiced/brown” or imported styles, and watch shared-fryer fries served with it.
