If the declared cocoa content of the coating matters most, compare the chocolate rather than relying on the word ‘dark’: Tesco lists 48% minimum cocoa solids and Sainsbury’s lists 35% minimum for their 300g digestives. For a road trip, pack size, the exact allergen label and cool, dry storage also matter; those cocoa figures do not tell you which biscuit will taste better or cope better with a warm car.
If the coating is your deciding factor, look for its stated cocoa-solids percentage. Tesco and Sainsbury’s declare different minimum figures for their listed dark chocolate digestives; neither figure describes the whole biscuit.
Choose a pack that suits the number sharing it and consider where you will keep it. The listed 266g and 300g products have cool, dry storage instructions, with directions for opened packs varying by product.
Check the physical pack before sharing with anyone who has an allergy. The listed biscuits have different ingredients and precautionary statements, including different information about milk and oats.
Start with the coating and the pack size, then read the nutrition, allergen and storage information for the exact biscuits you plan to take.
| Priority | What to check | Your needs |
|---|---|---|
| Cocoa declaration | Tesco lists 48% minimum cocoa solids in its dark chocolate and Sainsbury’s lists 35% minimum. Separately, their listings say dark chocolate makes up 30% and 27% of the respective biscuits. | I care about the declared cocoa content of the coating, rather than assuming every biscuit labelled ‘dark’ uses the same chocolate. |
| Serving information | For the listed biscuits, Sainsbury’s gives 3.5g sugars per biscuit, Tesco 4.2g and McVitie’s 4.4g. Check biscuit size and use the same nutrition basis when comparing packs. | If I expect to have biscuits at several stops, I want to know what the stated serving represents. |
| Pack and storage | The listed McVitie’s pack is 266g; the Tesco, Sainsbury’s, ASDA and M&S packs are 300g. Check cool, dry storage directions and what the pack says to do after opening. | Will the pack suit everyone sharing it, and can I keep opened biscuits as directed during the trip? |
| Allergens | Read ingredients and precautionary statements on the physical pack. Tesco says its listed biscuits may contain milk; Sainsbury’s lists milk and soya ingredients and warns about oat allergy. | Before I offer a biscuit to someone else, I need to check the exact pack against their relevant allergies. |
The percentage of cocoa solids in the chocolate is different from the percentage of chocolate in the whole biscuit. Neither figure alone describes its nutrition or establishes how it will taste.
Compare the two declarations separately, then compare nutrition using equivalent per-biscuit or per-100g figures.

This single 400g pack is an option when several people plan to share one open pack. Check its label for cocoa, nutrition, allergen and after-opening details rather than applying figures from a different pack.
No. Tesco declares 48% minimum cocoa solids in the chocolate on its listed 300g digestives, while Sainsbury’s declares 35% minimum on its listed 300g pack. These are figures for the chocolate, not the whole biscuit.
