Regular dark-chocolate buyers
If you keep a bar in the cupboard for eating during the week, consider its cocoa level, flavour and pack size before settling on one to buy regularly.
Who is this for?
High-cocoa shoppers
If you already enjoy a pronounced cocoa taste or specifically want a bar with no added sugar, 100% cocoa is a distinct option rather than an automatic upgrade from 70%.
Allergen-aware buyers
If milk, nuts or other allergens affect your choice, read the ingredients and precautionary statements on the exact current pack. A vegan-recipe description does not establish milk-allergy suitability.
What should you check?
Decide whether the chocolate is mainly for eating or baking, then compare the exact bars for cocoa level, ingredients, pack size and flavour.
| Priority | What to check | Your needs |
|---|---|---|
| Cocoa and sweetness | Read the cocoa-solids percentage, ingredients and sugars per 100g on the exact pack. Percentage alone does not give its full nutrition profile. | I want a dark bar I will enjoy regularly, rather than choosing the highest cocoa percentage by default. Montezuma's describes its Absolute Black as 100% cocoa with no added sugar; that is a different choice from a 70–72% bar. |
| Intended use | Check whether the product is an eating bar or is labelled for cooking. Marks & Spencer lists a 125g, 72% Swiss Extra Fine eating bar separately from its 100g, 70% dark cooking chocolate. | If I am buying for cakes or desserts, I want the cooking product on my list; for a piece of chocolate to eat, I am choosing a bar for its flavour. |
| Allergens | Read the current ingredients, declared allergens and any “may contain” statement. The Food Standards Agency explains that precautionary wording indicates an allergen could be unintentionally present. | I need to assess the exact pack for the allergens relevant to me, even if its recipe is described as vegan. |
| Pack size | Check the stated weight and whether you are comparing the same type of product. Bars referenced here include 90g, 100g and 125g formats. | A smaller bar may suit what I plan to eat this week; for baking, I need to check that the pack contains enough for my recipe. |
| Plain or flavoured | Read the full product name and ingredients rather than relying on the cocoa percentage alone. A bar with raspberry pieces is not a plain 70% bar. | I might want a fruit-flavoured dark bar for eating, but I would choose a plain bar when that is what my recipe calls for. |
Common buying mistakes
-
Treating cocoa percentage as the whole nutrition story
Cocoa percentage helps distinguish formulations, but does not state the sugars per 100g or tell you whether you will enjoy eating the bar.
Compare the ingredients and nutrition panels of the exact products. If you are considering 100% cocoa for regular eating, try a single bar before making it your usual choice.
-
Assuming a vegan recipe is suitable for a milk allergy
Lindt says its Excellence 70% bar is made to a vegan recipe but is manufactured in a facility using milk and is not suitable for people with a milk allergy.
Check the current pack’s allergen and precautionary statements rather than relying on a dietary description alone.
-
Relying on an older online food listing
Marks & Spencer warns that product information can change, which matters when ingredients or allergens determine what you can buy.
Use a listing to narrow your choice, then check the current pack before buying, particularly for allergy or dietary requirements.
Brand and product-line references
These examples illustrate different dark-chocolate formats; the details apply to the named products, not every bar from each brand.
Green & Black's
Its Organic Dark 70% is a 90g eating bar.
- The product information states that its cocoa, sugar and vanilla are traded in compliance with Fairtrade standards.
- The bar may contain nuts and milk; check the current pack if either matters to you.
Divine
Divine lists a plain 70% dark chocolate bar in a 90g format.
- The brand describes the plain bar as made with Fairtrade ingredients.
- Its listed precautionary information includes gluten, milk and nuts. Check the exact variant: a raspberry bar is not the plain bar.
Lindt
Excellence Dark 70% is a 100g plain dark bar.
- Lindt states that this bar contains at least 70% cocoa solids.
- Lindt says that, despite its vegan recipe, manufacture in a facility using milk makes this product unsuitable for people with a milk allergy.
Montezuma's
Absolute Black is a 90g option for someone deliberately choosing 100% cocoa.
- Montezuma's lists cocoa mass as its only ingredient and states that it has no added sugar.
- Its precautionary statement includes milk, nuts and peanuts.
Hotel Chocolat
The 70% Dark Chocolate Slab Selector offers a slab format rather than a standard plain bar.
- The named selector gives shoppers a 70% dark slab option.
- Check the current product or pack information for ingredients and allergens before an allergy-sensitive purchase.
M&S
The range includes a 125g Swiss Extra Fine 72% eating bar and a separate 100g dark cooking chocolate with at least 70% cocoa solids.
- The distinct eating and cooking products make intended use a useful first check.
- Marks & Spencer advises checking the current label because product information can change; its 72% eating bar is not suitable for people with certain listed allergies.

Questions about choosing dark chocolate
Is 70% dark chocolate a sensible starting point for a weekly shop?
Yes, if you want a dark eating bar but are unsure whether you would enjoy 100% cocoa. Try one 70–72% bar before making it a regular purchase, and check its ingredients and nutrition panel for the details that matter to you.
Does a higher cocoa percentage automatically tell me how much sugar is in a bar?
No. Compare sugars per 100g on the exact nutrition panels rather than calculating them from cocoa percentages. Montezuma's describes its Absolute Black as a 100% cocoa bar with no added sugar, but that does not describe every high-cocoa product.
Is a vegan dark-chocolate bar suitable for someone with a milk allergy?
Do not assume so. Lindt says its Excellence 70% bar is made to a vegan recipe but is not suitable for people with a milk allergy because it is manufactured in a facility using milk. Read the current pack’s allergen and precautionary statements.
What does “may contain” mean on a chocolate label?
The Food Standards Agency explains that precautionary allergen labelling communicates that a regulated allergen could be unintentionally present. Check the exact current pack rather than interpreting “may contain” as confirmation that the allergen is absent.
Can I rely on an online listing for chocolate ingredients and allergens?
Check the current product label before buying, especially when an allergen affects your choice. Marks & Spencer advises against relying solely on online food information because products can be redeveloped and their details can change.
