What should you compare?
Start with the cocoa figure if that is your main reason for choosing dark chocolate, then check the portion, nutrition panel and allergen wording on the same product.
| Priority | What to check | Your needs |
| Cocoa content |
Read the cocoa-solids minimum for the exact chocolate. Marks & Spencer lists 85% for its Collection mint bar; Waitrose & Partners lists 55% for Mint Thins, while Sainsbury’s lists 47% for Lindt Excellence Dark Mint and 43% for After Eight. |
I’m looking for a more cocoa-led chocolate, so “dark” on its own does not tell me enough. |
| Sugars and portion |
Compare sugars per 100 g, then the figure for the amount you plan to eat. Waitrose & Partners lists 3.0 g sugars per Mint Thin; Sainsbury’s lists 17.2 g per three After Eight mints. Those are different serving sizes, not a like-for-like comparison. |
For a small elevenses treat, I want to judge the amount I’ll actually have rather than assume a higher cocoa percentage means less sugar. |
| Allergens |
Check the current ingredients and precautionary statement. Sainsbury’s describes its Free From dark chocolate mints as milk and gluten free; Marks & Spencer says its 85% mint bar is not suitable for people with milk, nut or peanut allergy. |
If I need to avoid an allergen, a vegan label or the word “dark” is not enough to establish suitability. |
| Serving format |
Decide whether a bar, a single thin or fondant squares suit the occasion. Check per-piece information where it is given and the pack size if you are buying to share. |
I might want one countable mint with a drink, a piece broken from a bar, or squares to offer to others. |

Questions about dark chocolate mints
How can I identify a higher-cocoa dark mint?
Read the cocoa-solids minimum on the exact product rather than relying on “dark”. Marks & Spencer lists 85% for its Collection mint bar, Waitrose & Partners lists 55% for Mint Thins, and Sainsbury’s lists 47% for Lindt Excellence Dark Mint and 43% for After Eight.
Does more cocoa mean less sugar?
Not necessarily. Compare total sugars on the exact pack per 100 g and for the amount you intend to eat; a cocoa-solids percentage is not a sugar figure. If the pack uses traffic-light labelling, read it alongside the nutrition table rather than comparing differently sized servings as though they were equal.
Which dark mint is described as milk and gluten free?
Sainsbury’s describes its Taste the Difference Free From Dark Chocolate Mints as milk and gluten free. If suitability is critical, check the current pack’s ingredients and precautionary information for any other allergens you need to avoid.
Are dark chocolate mints dairy-free?
Do not assume so. Sainsbury’s lists milk fat in Lindt Excellence Dark Mint and milk butterfat in After Eight; Waitrose & Partners says Mint Thins may contain milk, while Marks & Spencer says its 85% mint bar is not suitable for people with a milk allergy. Check the specific pack.
Which format works for one piece at elevenses?
A countable thin makes a one-piece serving straightforward to identify: Waitrose & Partners lists 28 kcal and 3.0 g sugars per Mint Thin. A bar can also be portioned, but check its own nutrition panel for the amount you break off.
