Coeliac shoppers seeking dark chocolate
You want a dark-chocolate digestive, but the biscuit must also be gluten-free. The examined conventional dark varieties list wheat, so the coating cannot settle the choice.
Who is choosing?
Shoppers who can eat gluten-free oats
If milk chocolate is acceptable, the identified Tesco, Sainsbury’s and Asda Free From digestives provide gluten-free, oat-based recipes to assess. Coeliac UK notes that a small number of people with coeliac disease remain sensitive to gluten-free oats.
Shoppers considering a different biscuit base
Schär’s Digestive Choc lists maize, soya and buckwheat ingredients rather than oats. Its published ingredients are worth checking if oats are a concern, but its coating is milk chocolate and the ingredient list is not an oat-free certification.
What should you check?
Start with the exact biscuit’s gluten-free claim, then check the coating, flour blend and current pack details. The survey figures below concern gluten-free shopping generally, not digestive-biscuit preferences.
| Priority | What to check | Your needs |
|---|---|---|
| Gluten-free suitability | Check the claim on the exact variant and read the biscuit ingredients. Coeliac UK says the UK gluten-free claim is subject to a limit of 20 mg/kg gluten; the examined conventional dark digestives list wheat. | I need the whole biscuit, not just its coating, to meet a gluten-free requirement. Among 3,785 respondents to Coeliac UK’s 2025 Shopping Habits survey, 74.7% trusted its Crossed Grain Trademark more than a gluten-free statement; that measures trust, not biscuit purchases. |
| Chocolate type | Read whether the coating is labelled dark or milk chocolate, then check the biscuit separately. Sainsbury’s lists at least 35% cocoa solids for its conventional dark coating, but that biscuit contains wheat. | If I want a darker coating, a gluten-free milk-chocolate digestive does not meet that flavour preference simply because its chocolate contains cocoa. |
| Oats and allergens | Check the flour blend and full allergen information. The identified Tesco, Sainsbury’s and Asda Free From recipes use gluten-free oats; Schär Digestive Choc lists a different blend. Coeliac UK says some people remain sensitive to gluten-free oats. | Gluten-free oats may matter to my choice, and I need to check any separate allergies independently of the gluten-free claim. |
| Exact pack and choice | Match the variant name to the current listing and read the pack when it arrives. Do not confuse a conventional dark digestive with a similarly named Free From product. | I want a suitable variant I can identify when ordering. In Coeliac UK’s 2025 survey of 3,785 respondents, 38.4% were happy with the overall range of gluten-free products in supermarkets; that figure does not measure digestive-biscuit availability. |
Common buying mistakes
-
Choosing by the dark coating alone
The examined McVitie’s, Asda, Sainsbury’s and M&S dark digestives list wheat in the biscuit; the M&S variant also lists barley malt extract.
Check the exact variant’s gluten-free claim and biscuit ingredients before considering its cocoa description.
-
Assuming a gluten-free coating is dark chocolate
The identified gluten-free coated digestives from Tesco, Sainsbury’s, Asda and Schär specify milk chocolate.
Check chocolate type and gluten-free suitability separately if both matter to your choice.
-
Reading ‘gluten-free’ as ‘oat-free’
The examined Tesco, Sainsbury’s and Asda Free From recipes use gluten-free oats. A gluten-free claim does not resolve individual oat sensitivity or separate allergies.
Read the complete flour blend, ingredients and precautionary statements on the pack.
Brand and product-line references
These are distinctions between specific listed biscuits, not claims about every product each brand makes.
McVitie’s
Its examined 266g Dark Chocolate Digestives are a conventional dark-coated comparison.
- Asda’s listing specifies a 30% dark-chocolate coating for this variant.
- The same listing includes wheat flour and wholemeal wheat flour in the biscuit.
Crawford’s
The examined 400g plain digestive is a conventional biscuit comparison, not an identified dark-coated option.
- Iceland’s ingredient listing for this variant includes wheat flour.
Tesco
Its examined Free From Chocolate Digestives 166g offer a gluten-free, oat-based coated biscuit.
- Tesco describes the biscuit as gluten-free and made with gluten-free oat flour.
- Tesco specifies milk chocolate, not dark chocolate.
Sainsbury’s
The examined conventional dark and Free From chocolate digestives are distinct variants.
- Sainsbury’s labels its 166g oat-based Free From chocolate digestive gluten-free and suitable for coeliacs.
- That Free From variant has milk chocolate; the separate 300g dark variant lists wheat despite specifying at least 35% cocoa solids in its chocolate.
Asda
Its examined conventional dark and Free From chocolate digestives require separate label checks.
- Asda labels the 166g Free From variant gluten-free and lists gluten-free oat ingredients.
- That variant’s coating is milk chocolate; Asda’s separate 300g dark digestive contains wheat.
M&S
Its examined Dark Chocolate Digestives 300g are a conventional dark-coated variant.
- M&S lists wheat flour, wholemeal wheat flour and barley malt extract for this product. A separate Free From biscuit range does not change this variant’s ingredients.
Schär
Digestive Choc is a gluten-free coated digestive with a different published biscuit-base recipe.
- Schär lists maize, soya and buckwheat ingredients rather than oats for Digestive Choc.
- Schär identifies its 29% coating as milk chocolate. Its stated minimum 35% cocoa content does not make the coating a dark-chocolate product.
Joybuy digestive option
The Joybuy option here is a gluten-free digestive for shoppers who do not require a chocolate coating. It is not Schär Digestive Choc or a dark-chocolate digestive.

Questions about choosing
Does dark chocolate make a digestive suitable for coeliacs?
No. The whole biscuit needs checking. Sainsbury’s lists at least 35% cocoa solids in its examined dark digestive’s chocolate, but also lists wheat flour in the biscuit; check the exact product’s gluten-free claim and ingredients.
What does ‘gluten-free’ mean on a UK biscuit?
According to Coeliac UK and Food Standards Scotland, a UK gluten-free claim is subject to a limit of no more than 20 mg/kg (20 ppm) gluten. Read the ingredient and allergen information as well when choosing a particular pack.
What if a gluten-free digestive contains oats?
Coeliac UK says most people with coeliac disease can eat oats labelled gluten-free, but a small number remain sensitive to them. Check that the oats are specified as gluten-free and, if they cause continuing problems, discuss their use with a health professional.
Is the Crossed Grain Trademark required for a gluten-free biscuit?
No. The UK gluten-free claim has a regulated gluten limit; Coeliac UK’s Crossed Grain Trademark is a separate scheme. Greater trust in the trademark among respondents to Coeliac UK’s 2025 shopping survey does not change the threshold for a gluten-free claim.
What if the delivered pack differs from its online listing?
Read the delivered pack’s current gluten-free claim, ingredients and allergen statements before eating it. If they differ from the listing in a way that affects your choice, ask the retailer or manufacturer to clarify the discrepancy.
