Who is choosing?

Cocoa-focused hosts

If the chocolate’s cocoa content matters to you, look for a declared cocoa-solids percentage. Read it separately from the proportion of chocolate in the biscuit.

Hosts catering for different dietary needs

Recipes and precautionary allergen warnings vary. Keep the original packs available so guests can check the ingredients relevant to them.

Hosts planning portions

Compare the serving estimate or biscuit count for the precise pack you intend to put out. Equal pack weights do not necessarily mean equal listed serving estimates.

What should you compare?

Start with the chocolate declaration if cocoa content drives your choice, then check the pack format and ingredients for the people you are serving.

PriorityWhat to checkYour needs
Cocoa declaration Compare cocoa-solids minima within the chocolate, not with whole-biscuit figures. Tesco Groceries states 48% minimum cocoa solids in chocolate comprising 30% of its biscuit; Sainsbury’s states 35% minimum in chocolate comprising 27% of its biscuit. I want a declared figure for the chocolate rather than assuming that a dark coating tells me its cocoa content. Those figures alone cannot tell me which biscuit I would prefer with coffee.
Texture with coffee Read texture descriptions as descriptions, not coffee-dunking test results. Tesco calls its biscuit crumbly and crunchy; Ocado’s M&S listing attributes a crunchier texture to demerara sugar. If I plan to dunk biscuits, texture matters to me, but I will not treat a description or a result for a different biscuit variant as a tested advantage here.
Ingredients and allergens Check the exact pack’s ingredient list and precautionary warnings, including those concerning milk, soya and wheat. Keep the packaging available when serving; the Food Standards Agency recommends this for community and charity events in England, Wales and Northern Ireland. Guests need to be able to inspect the label for their own requirements. A dark chocolate coating does not mean a biscuit is milk-free.
Portions and storage Check whether the listing gives a biscuit count or a serving estimate. Tesco Groceries lists 16 biscuits for McVitie’s 266g pack; Sainsbury’s lists approximately 18 servings for its 300g pack, while Ocado lists approximately 17 for M&S 300g. Follow the chosen pack’s after-opening instructions. For a larger gathering, I would plan from the count or serving size on the pack I buy, rather than weight alone. Storage instructions also matter if there are leftovers.

What is easy to misread?

  • Taking the chocolate’s cocoa percentage as the biscuit’s

    That makes the cocoa content of the chocolate sound like a percentage of the entire biscuit. Tesco Groceries, for example, gives separate figures for the chocolate’s cocoa-solids minimum and the chocolate’s share of the biscuit.

    Read both figures and check that any percentages you compare describe the same part of each product.

  • Assuming dark chocolate means milk-free

    The checked McVitie’s, Sainsbury’s, M&S and Asda product information lists milk-derived ingredients; Tesco’s listing says its biscuit may contain milk.

    Keep the physical packaging for guests to check the full ingredients and warnings before eating.

  • Planning servings from pack weight alone

    Sainsbury’s and Ocado’s M&S listings give different approximate serving estimates for their respective 300g packs.

    Use the serving estimate or biscuit count for the exact variant, and check the stated serving size when planning quantities.

Brand references

These details concern the named dark chocolate digestives, not every biscuit made by each brand.

Tesco

Tesco’s 300g dark chocolate digestives have a declared cocoa-solids minimum for their chocolate coating.

  • Tesco Groceries lists chocolate at 30% of the biscuit and a minimum of 48% cocoa solids within that chocolate.
  • The listing says the product may contain milk; the cocoa declaration does not establish its taste with coffee.

Sainsbury’s

Sainsbury’s 300g dark chocolate digestives also have a declared cocoa-solids minimum.

  • Sainsbury’s lists chocolate at 27% of the biscuit, with a minimum of 35% cocoa solids within that chocolate, and approximately 18 servings per pack.
  • Its product information lists milk and soya ingredients and warns that manufacturing methods make it unsuitable for people with an oat allergy.

McVitie’s

McVitie’s dark chocolate digestives come in several pack formats; Tesco Groceries lists 16 biscuits for the 266g pack.

  • McVitie’s describes its dark variant as containing 30% dark chocolate.
  • Its listed ingredients include butter oil from milk and soya lecithin. The chocolate proportion is not a cocoa-solids percentage.

M&S

Ocado lists M&S dark chocolate digestives as a 300g pack with approximately 17 servings.

  • Ocado lists 32% chocolate and describes a crunchier texture associated with demerara sugar.
  • The texture description is not a comparison test; the listing includes barley, milk, soya and wheat among the ingredients.

Asda

Asda’s 300g dark chocolate digestives are another dark-coated pack to compare by ingredients and storage instructions.

  • Asda lists 30% dark chocolate and instructs customers to keep the opened pack in an airtight container and consume it within seven days.
  • The listing identifies milk, soya and wheat among its allergens. Its 30% chocolate proportion does not describe cocoa solids within the chocolate.

Common questions

Does Tesco’s 48% cocoa figure describe the whole biscuit?

No. Tesco Groceries states that dark chocolate makes up 30% of its biscuit and that the chocolate contains at least 48% cocoa solids. The two percentages have different bases.

Can I assume dark chocolate digestives are milk-free?

No. The checked McVitie’s, Sainsbury’s, M&S and Asda product information lists milk-derived ingredients, while Tesco’s listing warns that its product may contain milk. Check the physical pack against each guest’s requirements.

How should I store opened biscuits?

Follow the instructions on the pack you bought. The checked Sainsbury’s and M&S listings specify an airtight container after opening; Asda additionally says to consume its biscuits within seven days of opening.

What should I keep available at a community coffee morning?

For community or charity events in England, Wales and Northern Ireland, Food Standards Agency guidance updated in September 2026 recommends keeping food packaging so guests can check it. If you are unsure whether your particular food activity requires registration, ask the local authority; it may decide that very limited, infrequent activity does not require it.
