Dark-chocolate seekers
If the chocolate itself matters most, compare any stated cocoa-solids minimum with the chocolate’s share of the biscuit. They measure different things.
Who is choosing for the tin?
Office tin organisers
For repeated sharing, check the pack’s listed portions and storage directions, and keep its ingredient information available after moving biscuits into a tin.
Colleagues checking allergens
Read the ingredients and precautionary statements on the pack being shared. A dark-chocolate description alone does not establish that a biscuit is suitable for someone avoiding milk.
What should you check?
Start with the chocolate figures and pack format, then check whether the biscuits can be shared and stored with their label information close at hand.
| Priority | What to check | Your needs |
|---|---|---|
| Chocolate figures | Read the percentage of chocolate in the biscuit separately from the minimum cocoa-solids percentage in that chocolate. Tesco Groceries lists 30% chocolate and at least 48% cocoa solids in the coating of its 300g digestive; its Fox’s Rounds listing gives 71% chocolate and at least 35% cocoa solids in that chocolate. | I want to know what a dark-chocolate percentage actually describes before comparing biscuits. |
| Sharing format | Compare listed servings for the exact pack as well as pack weight. Decide whether loose biscuits or separate bars work better for the way colleagues share food. | There should be enough suitable portions for the people using the tin, without judging the pack by weight alone. |
| Allergen information | Check the purchased pack’s ingredients and precautionary statements. Keep the original wrapper accessible if biscuits are transferred into a communal tin. | I need colleagues to be able to check the label before taking a biscuit, rather than relying on the word ‘dark’. |
| Storage | Follow the pack’s directions after opening, including an airtight container where specified. Check the best-before date when planning how quickly to use a pack; the Food Standards Agency describes this date as relating to quality, unlike a use-by date. | If a pack stays in the office between breaks, I want to store the opened biscuits as its label directs. |
Common buying mistakes
-
Treating chocolate percentage as cocoa-solids percentage
Tesco Groceries lists chocolate as 30% of its 300g digestive, with at least 48% cocoa solids in that chocolate. Its Fox’s Rounds listing gives 71% chocolate, with at least 35% cocoa solids in the chocolate. The figures use different denominators.
Check what each percentage measures before deciding which chocolate description meets your preference.
-
Assuming ‘dark’ means milk-free
Milk appears in several of the checked dark-biscuit recipes, and Tesco’s listed dark chocolate digestive carries a may-contain-milk statement.
Keep the purchased packaging with the tin so colleagues can check its ingredients and precautions against their own requirements.
-
Choosing on pack weight alone
Pack weight does not tell you how many portions colleagues are likely to take, while an opened pack still needs to be stored as directed.
Check the listed servings for the exact pack, then follow its instructions for storage after opening.
Relevant brand and product references
These details refer to the specified products and listings, not every biscuit made by each brand.
Tesco
Tesco Groceries lists a 300g dark chocolate digestive with both a coating proportion and a cocoa-solids minimum.
- The listed biscuit contains 30% dark chocolate; that chocolate contains at least 48% cocoa solids.
- These figures apply to this digestive. Its listing also says it may contain milk.
Fox’s
The listed dark chocolate Rounds have a shortcake base rather than a digestive base.
- Tesco Groceries lists the Rounds as 71% dark chocolate, with at least 35% cocoa solids in that chocolate.
- Those figures describe the Rounds, not the wider Fox’s assortment, which Fox’s Burton’s Companies UK describes as including milk, white and dark chocolate varieties.
Sainsbury’s
Sainsbury’s lists its own-label dark chocolate digestives in a 300g pack.
- The listing specifies 27% dark chocolate, containing at least 35% cocoa solids.
- The listed product is unsuitable for customers with an oat allergy because of its manufacturing methods.
McVitie’s
McVitie’s lists dark chocolate digestives in several pack sizes, including 266g and 400g.
- The manufacturer lists dark chocolate as 30% of its digestive recipe.
- Compare the pack you intend to buy if a cocoa-solids percentage or particular allergen statement matters to you.
Penguin
McVitie’s Penguin Original is a separately portioned chocolate biscuit bar.
- McVitie’s lists seven bars as the typical number per pack of the checked Original product.
- Its listed coating is milk-chocolate-flavour, so this product does not meet a dark-chocolate preference.
Club
McVitie’s Club Orange is another biscuit-bar format to consider when separate portions matter.
- The checked product combines a chocolate-flavour coating with orange flavouring.
- McVitie’s describes that coating as milk-chocolate-flavour; it does not establish a dark-chocolate option.

Questions about sharing and storage
Does 48% cocoa solids mean 48% of the Tesco biscuit is cocoa?
No. Tesco Groceries says dark chocolate makes up 30% of its listed 300g digestive and that this chocolate contains at least 48% cocoa solids. The percentages describe different parts of the product, not the cocoa content of the whole biscuit.
How should I store biscuits after opening the pack?
Follow the purchased pack’s directions. The checked Tesco, Fox’s and Sainsbury’s listings call for cool, dry storage and an airtight container after opening; keep the original label accessible if the biscuits go into an office tin.
Are dark chocolate biscuits necessarily suitable for someone avoiding milk?
No. The checked Fox’s, Sainsbury’s and McVitie’s recipes list milk ingredients, while Tesco’s checked digestive says it may contain milk. Check the actual pack against the colleague’s requirements rather than relying on ‘dark’ in the product name.
How can I compare packs for a shared office tin?
Compare the exact packs’ weights and listed servings, then consider whether loose biscuits or separate bars suit the way colleagues share food. Keep the chosen product’s label available for ingredient checks.
