Choose a high-cocoa dark chocolate by checking the ingredients, precautionary allergen statement and any explicit suitability notice for the exact bar—not by its cocoa percentage or a vegan claim. Plain high-cocoa bars can still carry warnings for milk, nuts, peanuts, soya or sesame, so check the current pack against the intended eater’s specific allergen requirements before choosing one.
Who needs to check the label?
Shoppers avoiding milk
A vegan recipe or dark-chocolate label does not settle a milk-allergy decision. Lindt’s 70%, 85% and 99% EXCELLENCE product pages describe vegan recipes but say those bars are not suitable for people with a milk allergy because they are made in a facility using milk. Check the exact bar’s ingredients, warnings and suitability notices.
Shoppers avoiding nuts, peanuts, sesame or soya
Read both the ingredient list and any “may contain” statement. Warnings differ between products: Lindt lists possible nuts, soya and sesame on the cited EXCELLENCE bars, while Montezuma’s lists possible nuts and peanuts on Absolute Black.
People buying for someone else
Confirm which allergen the recipient needs to avoid before choosing a bar. Match that requirement to the current label on the exact product; a dark colour, high cocoa percentage or familiar brand cannot answer that question for them.
What should you check first?
Start with the intended eater’s allergens, then check the exact product’s ingredients and warnings. Consider cocoa percentage and flavour only after those checks.

What to check |
Your needs |
| Ingredients |
Read the full ingredient list for the exact bar. Check any explicit “not suitable” notice for the named allergy. |
I need to know whether this particular recipe contains an allergen the eater avoids, rather than relying on the word “dark”. |
| “May contain” warnings |
Look for each relevant allergen in the precautionary statement, even if it is absent from the recipe. The Food Standards Agency explains that “may contain” communicates possible unintended allergen presence. |
A short ingredient list is not enough for me if the pack also warns about an allergen the eater must avoid. |
| Current pack |
Match the name, cocoa percentage and format to the wrapper in hand. Read its current ingredients and allergy advice rather than relying solely on an online listing; M&S warns that its food information can change. |
If I’m buying again, I still want to check this pack rather than assume its labelling matches a previous purchase. |
| Bar or assortment |
Check whether the product is plain, flavoured or filled, and read the declaration for the whole product. An M&S dark-chocolate selection, for example, includes a hazelnut-praline centre. |
For a gift box, I need information about the assorted pieces—not just the dark-chocolate coating. |
| Cocoa percentage |
Use the stated percentage to identify the variant you want. Check that variant’s own allergy information; percentages such as 70%, 85% and 99% do not establish a shared allergen profile. |
Once a bar meets the eater’s allergen requirements, I can choose the cocoa level and flavour they prefer. |
Common mistakes to avoid
-
Taking “dark” or “vegan” to mean suitable for a milk allergy
Lindt says its cited EXCELLENCE bars have vegan recipes but are not suitable for people with a milk allergy. Montezuma’s says Absolute Black is made without milk while also declaring possible traces of milk.
Use recipe descriptions to find products to examine, then check the exact pack’s ingredients, precautionary statement and any explicit suitability notice.
-
Using another variant’s allergy information
A plain bar, a flavoured bar and a filled assortment may have different ingredients and warnings. The cocoa percentage also identifies a particular variant, not an allergy-suitability threshold.
Match the declaration to the product name, cocoa percentage and format you are buying.
-
Relying on an old product page or pack image
M&S advises shoppers that online ingredients and allergen information may change and that they should read the product label.
Recheck the wrapper on the product in hand before it is eaten, including when it is a repeat purchase.
-
Assuming every piece in a dark-chocolate selection is plain
An M&S dark-chocolate selection includes filled pieces such as hazelnut praline. The description “dark chocolate” does not describe every ingredient in the box.
Check the allergen declaration for the entire assortment against the intended eater’s requirements.
Brand and product-line references
These examples show why allergy information needs checking by product and variant, not by brand name.
Lindt
The UK EXCELLENCE range provides plain dark examples at 70%, 85% and 99% cocoa.
- Lindt’s pages identify these variants as made to vegan recipes.
- The same pages say they are not suitable for people with a milk allergy and list possible nuts, milk, soya and sesame. Check the declaration for the exact bar.
Montezuma’s
Its dark range includes Absolute Black, a 100% cocoa bar.
- Montezuma’s describes Absolute Black as made without milk or soya and with no added sugar.
- Its allergen declaration says it may contain traces of milk, nuts and peanuts. The recipe description alone does not establish suitability for those allergies.
Divine
Divine lists a 70% dark chocolate bar that shoppers can identify by its specific variant.
- The product page labels the 70% bar vegan.
- It also states “may contain” gluten, milk and nuts. Check those warnings against the intended eater’s requirements.
M&S
Its listing for 75% Cocoa Single Origin Dark Chocolate gives explicit product-level allergy exclusions.
- The listing states which named allergies make this particular bar unsuitable.
- M&S marks it as not suitable for milk, nut or peanut allergies and advises reading the product label because online information can change.
Hotel Chocolat
Its range includes an 85% dark-chocolate slab.
- The cocoa percentage and slab format identify the product to check.
- Neither the percentage nor a general description of the slab establishes its suitability for a particular allergy. Check its current product-specific ingredients and allergen declaration.
Green & Black’s
A UK listing identifies a 70% dark chocolate bar.
- The stated cocoa percentage helps distinguish this bar from other variants.
- Dark or organic positioning does not establish allergy suitability. Read the current declaration on the exact pack.

Questions about allergy information
Is dark chocolate automatically suitable for a milk allergy?
No. Lindt says its 70%, 85% and 99% EXCELLENCE bars are made to vegan recipes but are not suitable for people with a milk allergy because they are manufactured in a facility using milk. Check the ingredients and allergy notices for the exact bar rather than relying on its dark-chocolate description.
What does “may contain” mean on a chocolate bar?
It is precautionary allergen labelling about possible unintended allergen presence, rather than an ingredient deliberately used in the recipe. The Food Standards Agency describes “may contain” as a way to communicate that a regulated allergen could be present; check whether the named allergen matters for the intended eater.
Does a vegan label settle an allergy question?
No. A vegan claim does not replace the exact product’s ingredients, precautionary warnings or suitability notices. Lindt’s cited vegan-recipe bars carry a milk-allergy exclusion, while Divine’s vegan-labelled 70% bar says it may contain gluten, milk and nuts.
Is a retailer’s online allergen listing enough to choose a bar?
Use it to narrow down products, then read the current physical label before the chocolate is eaten. M&S states that ingredients and allergen information may change and advises shoppers not to rely solely on its online information.
