For a repeat weekly purchase, start by comparing plain 70–74% dark chocolate bars by cocoa percentage, pack size and the ingredients and allergen statements on the current wrapper. Choose a higher-cocoa or flavoured bar deliberately if that is what you enjoy; neither a higher percentage nor a vegan-recipe description establishes allergy suitability.
If you want one eating bar with the weekly shop, check the stated weight before choosing. The Lindt, Divine, Green & Black’s and M&S single-bar examples listed by their makers or retailers range from 90g to 125g; a gift selection, multipack or baking product serves a different purpose.
Read the declaration for the exact bar and size. Lindt, Divine, Green & Black’s and M&S give different milk, nut and other allergen warnings for the products discussed here, so neither the word “dark” nor a cocoa percentage settles suitability.
If a Fairtrade, organic or producer-ownership statement matters to you, check which claim applies to the particular bar. Divine and Green & Black’s make product-specific claims of this kind; they are not an independent comparison of the brands’ overall sourcing.
Settle on a plain or flavoured bar and a pack size you will use, then check the exact product information—particularly if ingredients or allergens affect your choice.
| Priority | What to check | Your needs |
|---|---|---|
| Cocoa and flavour | Read the stated cocoa percentage and check whether the bar is plain or flavoured. The documented single-bar options include 70%, 72% and 74% products; percentage alone does not tell you which flavour you will prefer. | I want a bar I will enjoy buying again, rather than choosing a higher cocoa number simply because it is higher. |
| Ingredients and allergens | Check the current ingredients list and allergen and precautionary statements for the exact variant. A vegan recipe does not establish suitability for someone with a milk allergy: Lindt says its EXCELLENCE 70% bar is not suitable for people with a milk allergy. | If I need to avoid an ingredient or allergen, the declaration for this particular wrapper matters more than “dark” or “vegan recipe” on its own. |
| Sourcing claims | Identify the precise Fairtrade, organic or other sourcing claim and the product it covers. Divine describes Fairtrade ingredients for its 70% bar; Tesco describes organic chocolate and Fairtrade ingredients for Green & Black’s Organic 70% bar. | A stated certification or sourcing approach may matter to me, but I do not want to treat different claims as an overall brand ranking. |
| Single-bar format | Confirm that the item is an eating bar rather than a multipack, gift selection or baking product, and compare the stated weights. The referenced plain bars include 90g, 100g and 125g formats. | One bar needs to suit how I use chocolate during the week; a larger format is not automatically the right substitute. |
Product warnings differ. Lindt’s EXCELLENCE 70% information says it is not suitable for a milk allergy; Divine’s 70% bar may contain gluten, milk and nuts; Tesco says Green & Black’s Organic 70% bar may contain nuts and milk. M&S lists further allergy exclusions for its 72% bar.
Read the current ingredients and precautionary wording for the exact bar. Do not use cocoa percentage or vegan-recipe wording in place of an allergy check.
A single 90g bar and a single 125g bar are different quantities, while a multipack or gift selection changes what you are buying altogether.
Check both the product type and the stated weight before adding it to a repeat shop.
M&S warns that ingredients, dietary information, nutrition and allergen details can change as products are redeveloped.
Use a listing to narrow your choice, then read the current wrapper before eating the bar, especially when an ingredient must be avoided.
The bars discussed include 70%, 72% and 74% options, while other dark-bar variants state higher percentages. A higher figure is a difference to consider, not proof that you will prefer the flavour.
Choose a plain percentage you expect to enjoy repeatedly, and select a higher-cocoa or flavoured variant because you want that particular bar.
These examples show different product formats and stated claims; each ingredient and allergen decision still belongs to the individual bar.

A 90g single bar for a plain 70% cocoa choice. Check the current wrapper if you need to avoid almonds, hazelnuts or milk, which the product information says it may contain.

At 180g, this is a larger single bar than the 90–125g examples above; consider whether that size suits your weekly shop. Its product information says it contains soya and may contain gluten, eggs, milk, peanuts and nuts.

A 100g single bar if you want a stated 72% cocoa option rather than 70%. The product information says it contains soya and may contain gluten, milk, nuts and peanuts.
No image available
This 90g bar is a distinct 85% cocoa choice, not an assumed upgrade from a 70–74% bar. Its product information says it may contain nuts and milk; check the current wrapper where allergies matter.
No image available
A 90g flavoured alternative if you want raspberry rather than a plain weekly bar. The dietary information for this variant conflicts on milk, so do not assume it is vegan or suitable for a milk allergy; check the current wrapper.
Yes, if you want to start with a plain dark bar: Lindt, Divine and Green & Black’s each have a documented 70% single-bar example. Treat the percentage as a way to narrow the choice, not a guarantee that you will prefer it to a 72% or 74% bar.
Not automatically. Lindt says its EXCELLENCE 70% bar is made to a vegan recipe but is not suitable for people with a milk allergy. Read the current allergen statement for the exact product rather than relying on vegan-recipe wording.
Check the wrapper as well, especially if you need to avoid an ingredient. M&S advises reading the label because its products and their ingredient, nutrition and allergen information can change.
Divine describes Fairtrade ingredients for its plain 70% bar. Tesco describes Green & Black’s Organic 70% bar as organic and identifies Fairtrade cocoa, sugar and vanilla. Check that the claim belongs to the exact variant you are considering; these statements do not establish an overall comparison between brands.
