For a Bonfire Night treat to pass around, a plain bar around 70% cocoa is a sensible starting point if the group likes dark chocolate but has no known preference for higher cocoa levels. Choose an 85% bar for someone who already enjoys that style, or a flavoured bar when you know the additions will appeal. Before sharing, check the exact wrapper: a vegan recipe does not establish suitability for someone with a milk allergy.
Who are you buying for?
Hosts sharing with dark-chocolate fans
A single bar can be passed around after food or served with hot drinks. If several people will try it, consider whether they all enjoy a pronounced cocoa flavour before choosing a high-cocoa or flavoured option.
Someone with a known high-cocoa preference
If the recipient actively chooses higher-cocoa chocolate, an 85% bar is a more targeted purchase than a 70% bar. A 100% cocoa bar calls for a particularly clear preference for unsweetened chocolate.
Shoppers checking dietary or allergy needs
Check ingredients and precautionary allergen statements on the exact bar before sharing it. Do not treat a vegan-recipe claim as confirmation that a product is suitable for someone with a milk allergy.
What should you check?
Start with the recipient’s cocoa and flavour preferences, then check the exact bar’s ingredients and allergen information before it is served.
| Priority | What to check | Your needs |
| Cocoa level |
Compare the stated cocoa percentage. The options described here include bars around 70%, bars at 85% and a 100% cocoa option; percentage alone does not tell you whether someone will like a bar. |
I want dark chocolate the recipient will enjoy. If they regularly choose higher-cocoa bars, I can make that preference part of the decision. |
| Allergens |
Read the exact wrapper’s ingredients, highlighted allergens and any precautionary statement. Lindt says its EXCELLENCE 70% bar has a vegan recipe but is not suitable for people with a milk allergy. |
If I am sharing with someone who has an allergy, I need the information for the bar I will actually serve, not an assumption based on the word “vegan”. |
| Added flavours |
Check whether the bar is plain or contains additions such as chilli, ginger, fruit, nuts or praline. Check the ingredients and allergen information for the particular variant. |
For a mixed group, I would choose an added flavour only if I know it is wanted. |
| Sourcing claims |
Look for a claim on the specific bar rather than assuming it applies across a brand. Marks & Spencer describes its 85% dark bar as Fairtrade and made with cocoa beans from Peru. |
A stated sourcing attribute matters to me, but it does not answer my questions about flavour or allergy suitability. |
Common buying mistakes
-
Reading “vegan” as “milk-allergy suitable”
These describe different things. 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 made in a facility that uses milk.
Check the exact pack’s ingredients and precautionary statement. If you cannot establish whether it meets a recipient’s allergy needs, choose another bar or ask them before serving it.
-
Choosing the highest cocoa percentage by default
A preference for dark chocolate does not establish a preference for an 85% bar or Montezuma’s 100% cocoa Absolute Black.
Use what you know about the recipient’s usual choice. A plain bar around 70% leaves the higher-cocoa options for someone who specifically wants them.
-
Assuming a dark bar is plain
Dark-chocolate ranges also contain fruit, spice, nut and praline variants. A flavour that appeals to one guest may not suit the person you are buying for.
Check the exact variant before buying. For a mixed group, choose an added flavour only when you know it is welcome, and read its ingredient and allergen information.
-
Relying on a listing instead of the wrapper
The bar you receive is the one that will be shared, so its packaging matters when checking ingredients and allergens.
Confirm the exact bar at checkout and read its wrapper before serving, particularly if anyone has an allergy.

Frequently asked questions
Which cocoa percentage should I choose for a Bonfire Night dark chocolate bar?
A plain bar around 70% cocoa is a starting point when you know the recipient likes dark chocolate but not whether they enjoy higher-cocoa bars. Choose 85% for a known preference; Montezuma’s 100% cocoa Absolute Black is a more specific unsweetened choice.
Is vegan dark chocolate suitable for someone with a milk allergy?
Not necessarily. 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. Check the exact product’s packaging rather than relying on a vegan claim.
What allergen information should I check on a wrapped bar?
Read the ingredients, emphasised allergens and any precautionary statement on the exact pack. GOV.UK and Food Standards Agency guidance for England, Northern Ireland and Wales, alongside Food Standards Scotland guidance, explains allergen information requirements for prepacked food.
Should I choose a flavoured dark bar for a group?
Choose one when you know the intended recipients want that flavour. Montezuma’s lists dark bars with additions including chilli and ginger, while Hotel Chocolat’s dark range includes fruit- and nut-containing products. Check the ingredients and allergen information for the particular bar before sharing it.
