Shoppers checking cocoa content
If the word ‘dark’ is not specific enough, compare the declared cocoa solids in the chocolate separately from the amount of chocolate in the biscuit.
Who is buying in quantity?
Household and office stock-up buyers
If the biscuits will be eaten over several occasions, consider how many packs you will open at once, their best-before dates and the labelled storage directions.
What should you compare?
Start with what the cocoa figures measure, then check whether the pack format and dates fit how you will use the biscuits.
| Priority | What to check | Your needs |
|---|---|---|
| Cocoa declaration | Read the coating's cocoa-solids minimum separately from its share of the biscuit. Tesco states 48% minimum cocoa solids in chocolate that makes up 30% of its Dark Chocolate Digestives; Sainsbury's states 35% and 27% respectively for its 300g digestives. | I want a stated cocoa figure for the chocolate, rather than assuming that a biscuit labelled ‘dark’ has a particular cocoa content. |
| Pack format | Compare net weight and pack count for the exact product. McVitie's lists a 2 × 266g Dark Chocolate Digestives format; Tesco and Sainsbury's list 300g digestive packs, while the reviewed Fox's Rounds pack is 130g. | Will I use one larger pack promptly, or would two packs fit the occasions when I plan to open them? |
| Dates and storage | Check each pack's best-before date against your intended use. GOV.UK explains that best-before dates concern quality, rather than the safety meaning of use-by dates; follow the product's storage directions after opening. | I need the later packs to remain suitable for the occasions I have in mind, with space to store them as directed. |
| Ingredients and allergens | Read the exact pack's ingredients and allergen statement. McVitie's lists milk and soya in its Dark Chocolate Digestives; Tesco says its reviewed dark-chocolate digestives may contain milk. | Before sharing biscuits from a stock-up, I want to check the label for anyone whose ingredients or allergen requirements matter. |
What is easy to misread?
-
Taking the chocolate percentage to mean cocoa solids
Tesco states that dark chocolate makes up 30% of its digestives and contains at least 48% cocoa solids. The two percentages describe different parts of the product.
For a cocoa-focused choice, find the cocoa-solids declaration for the chocolate first, then compare how much chocolate the biscuit contains.
-
Assuming a twin pack supplies more biscuits than another format
A pack count alone does not show the total quantity. McVitie's lists a 2 × 266g format, while the reviewed own-label digestive packs are 300g each.
Compare the stated net weights and the number of packs you expect to open during your planned period.
-
Opening several packs before checking their dates
GOV.UK distinguishes best-before dates, which concern quality, from use-by dates, which concern safety. Opening packs also makes their after-opening storage directions relevant.
Check the dates when the biscuits arrive, keep unopened packs sealed until needed and follow each opened pack's storage instructions.
Brand and product-line references
These details describe the named products and formats, not every biscuit made by each brand.
Tesco
Tesco Dark Chocolate Digestives come in a 300g pack.
- Tesco declares at least 48% cocoa solids in the dark chocolate, which makes up 30% of this biscuit.
- The cocoa figure describes the chocolate, not the whole biscuit; the product information also says it may contain milk.
McVitie's
McVitie's lists Dark Chocolate Digestives in several sizes, including 2 × 266g.
- The maker states that dark chocolate accounts for 30% of the biscuit.
- That figure is not a cocoa-solids declaration. Check the exact pack if cocoa solids are decisive; the listed ingredients include milk and soya.
Sainsbury's
Sainsbury's Dark Chocolate Digestives are listed in a 300g pack.
- Sainsbury's states that dark chocolate is 27% of the biscuit and contains at least 35% cocoa solids.
- These figures apply to this product; check its pack ingredients and allergen information before sharing.
Fox's
Fox's Fabulous Chocolatey Dark Chocolate Rounds are shortcake biscuits in a 130g pack.
- The reviewed Tesco listing states that dark chocolate makes up 71% of these Rounds and contains at least 35% cocoa solids.
- The 71% figure is the chocolate's share of the biscuit, not its cocoa-solids percentage.
Bahlsen
Bahlsen describes Choco LEIBNIZ Dark as a crisp biscuit set into a dark-chocolate tablet.
- Its biscuit-in-chocolate format offers a different construction from a coated digestive.
- Check the exact pack's cocoa-solids declaration and quantity before comparing it with the digestives.

Questions before buying
Does ‘30% dark chocolate’ mean 30% cocoa solids?
No. It means dark chocolate makes up 30% of the biscuit, not that the chocolate contains 30% cocoa solids. Tesco, for example, separately declares at least 48% cocoa solids in the chocolate on its Dark Chocolate Digestives.
How do I decide how many packs to order?
Match the packs' best-before dates and storage directions to when you expect to eat them. GOV.UK says best-before dates concern quality rather than the safety meaning of use-by dates; check the dates on the packs you receive.
Does dark chocolate mean these biscuits contain no milk?
No. McVitie's lists milk in its Dark Chocolate Digestives ingredients, while Tesco says its reviewed dark-chocolate digestives may contain milk. Check the ingredients and allergen information on the exact pack before serving it to someone avoiding milk.
Are Penguin Original bars another dark-chocolate option?
Not according to McVitie's description of Penguin Original, which specifies a milk-chocolate-flavoured coating. Check the named variant rather than treating a chocolate-flavoured filling as evidence of a dark-chocolate coating.
