What should you check before choosing?
Choose the flavour and format you want first, then check the exact bar’s ingredients and allergen information before buying it for yourself or someone else.
| Priority | What to check | Your needs |
| Cocoa and flavour |
Compare cocoa percentage, the flavour description and the sugar figure per 100g on the bars you are considering. Percentage alone does not describe every flavour note. |
I would like some sweetness in a dark bar, or I am deliberately looking for a stronger cocoa taste. |
| Allergens |
Read the exact pack’s ingredients and precautionary statements for milk, nuts, peanuts and other relevant allergens. Do not use a vegan claim as an allergy-suitability statement. |
The person eating this bar needs its allergen information checked before I choose it. |
| Sourcing claims |
Check which ingredient or product carries a stated claim, such as Fairtrade. Read any qualification attached to that claim. |
I care about a specific sourcing claim, rather than a general premium description. |
| Pack format |
Confirm the weight and whether the item is one bar, a baton pack or a case. Check the current listing and the physical pack before purchase or gifting. |
I want one bar as a treat, not a multipack or a different chocolate format. |

Questions about choosing a bar
Should I choose 70%, 85% or 100% cocoa?
Start around 70% if you want dark chocolate with some sweetness; consider 85% for a more pronounced cocoa flavour. Choose 100% only if you want an unsweetened bar. Montezuma’s lists 0.6g sugars per 100g for its 100% Absolute Black, but cocoa percentage alone will not tell you all the flavour notes or allergens in another bar.
Is a vegan dark chocolate bar suitable for someone with a milk allergy?
Not automatically. Lindt says its EXCELLENCE 70% bar has a vegan recipe but is not suitable for people with a milk allergy because it is made in a facility that uses milk. Montezuma’s says its 100% Absolute Black is made without milk but may contain traces of milk, nuts and peanuts. Check the exact pack for the intended recipient.
Can I rely on an online listing for allergen information?
Use a listing to narrow your choice, then read the physical pack before eating or gifting the bar. M&S advises shoppers that ingredients, dietary and allergen information can change, so its product pages should not replace the label on the item purchased.
Does a 70% baton pack count as a single bar?
Not if you specifically want one conventional slab. Hotel Chocolat describes its 70% Dark Chocolate Batons as a pack of 15 fingers; check the stated pack format and weight when comparing it with a single 90g or 100g bar.
