Travellers comparing cocoa content
You want a stated cocoa-solids percentage for the coating, rather than relying on the word ‘dark’ or confusing it with the amount of chocolate in the biscuit.
Who is this choice for?
People packing hand luggage
Pack weight and protection from crushing matter when biscuits are travelling in your bag. Heathrow says most food can go in a cabin bag, though it may need additional screening; check your own airport and airline.
Travellers checking ingredients
If an allergy affects the purchase, read the ingredients and precautionary statements on the actual pack. A dark chocolate coating does not establish that a biscuit is milk-free.
What should you check before choosing?
Compare the coating declaration first if cocoa content matters to you, then check whether the pack and its label work for your journey.
| Priority | What to check | Your needs |
|---|---|---|
| Cocoa declaration | Compare cocoa solids within the coating: Tesco states 48% minimum and Sainsbury’s 35% minimum. Their respective 30% and 27% dark-chocolate ingredient shares measure something different. | I want a stated figure for the chocolate coating, rather than choosing on the word ‘dark’ alone. |
| Pack format | Compare the quantity you will carry. The cited McVitie’s single pack is 266g; the Tesco, Sainsbury’s, Asda and M&S packs are 300g. Protect biscuits from being crushed. | A smaller stated pack weight may suit my bag, but I also need a way to keep the biscuits intact. |
| Ingredients | Read the current pack’s full ingredient and precautionary allergy statements. The cited McVitie’s and Asda listings identify wheat, milk and soya. | Before buying for someone with an allergy, I need to check that exact pack—not infer suitability from its dark coating. |
| Journey rules | Check your departure airport’s food-screening guidance, your airline’s cabin-bag allowance and any destination import rules separately. | I want to know whether this pack fits my bag and what checks apply along my itinerary, rather than assuming one airport’s arrangements apply everywhere. |
Common buying mistakes
-
Reading the chocolate share as the cocoa percentage
Tesco lists dark chocolate as 30% of its biscuit’s ingredients and at least 48% cocoa solids within that chocolate. Sainsbury’s corresponding figures are 27% and 35%. The two types of percentage answer different questions.
Compare coating cocoa figures with coating cocoa figures, and chocolate ingredient shares with ingredient shares.
-
Assuming ‘dark’ means milk-free
The cited McVitie’s and Asda listings identify milk, while Tesco gives a ‘may contain milk’ precaution. The product name alone cannot settle an allergy-related decision.
Read the full ingredients and precautionary statements on the pack you buy.
-
Using one airport’s guidance for the whole trip
Heathrow says most food is allowed in cabin bags but may need additional screening. That does not establish the arrangements at another airport or the rules for bringing food into your destination.
Check your departure airport, airline and destination separately before travelling.
Brand and product references
These references describe particular UK dark chocolate digestive packs, not every product made by each brand.
Tesco
Tesco Dark Chocolate Digestives come in a 300g pack with separate figures for the chocolate ingredient and its cocoa content.
- Tesco states that dark chocolate makes up 30% of the biscuit and contains at least 48% cocoa solids.
- Check the current pack label before relying on the listed formulation.
McVitie’s
McVitie’s describes its 266g dark chocolate digestives as wheat biscuits topped with dark chocolate.
- The 266g single pack has a lower stated weight than the 300g packs described here.
- If cocoa percentage is decisive, check the coating declaration on the particular pack; the cited manufacturer and Asda descriptions do not give a comparable figure.
Sainsbury’s
Sainsbury’s 300g dark chocolate digestives have separate declarations for the coating’s ingredient share and cocoa content.
- Sainsbury’s lists 27% dark chocolate in the biscuit and at least 35% cocoa solids in that chocolate.
- The 35% figure describes the coating, not the whole biscuit.
Asda
Asda’s 300g dark chocolate digestives have a listed chocolate ingredient share and allergy information.
- Asda lists 30% dark chocolate and identifies milk, soya and wheat.
- The 30% chocolate share cannot be compared as a cocoa-solids figure.
M&S
M&S lists a 300g dark chocolate digestive pack and describes demerara sugar as adding crunch.
- The brand’s description gives a specific texture detail to consider.
- For a cocoa-led choice, check the pack for a comparable cocoa-solids declaration rather than treating the texture description as one.

Questions about travelling with digestives
Can I take digestives through airport security?
Heathrow says most food is allowed in cabin bags, although it may need additional screening. Check your departure airport’s guidance and your airline’s baggage allowance; Heathrow’s arrangements do not establish the rules at every airport.
Does ‘dark chocolate’ tell me how much cocoa is in the biscuit?
No specific cocoa percentage follows from the word ‘dark’. Tesco states at least 48% cocoa solids in its coating and Sainsbury’s states at least 35% in its coating; neither figure is the cocoa percentage of the whole biscuit.
How should I carry an opened pack?
Follow the pack’s storage directions and protect it from being crushed. Tesco specifies cool, dry storage and an airtight container once opened; Sainsbury’s also advises an airtight container after opening.
What should I check about allergens at an airport shop?
Read the ingredients and precautionary allergy statements on the actual pack before buying or eating it. A dark coating is not proof that a digestive is milk-free, and the cited product listings include both milk ingredients and a ‘may contain milk’ precaution on different packs.
Can I take leftover biscuits across a border?
Check the import rules for your destination separately from airport security rules. GOV.UK says biscuits may be brought into Great Britain from any country, but notes that Northern Ireland has different rules; that guidance does not establish what another destination permits.
