One-bar shoppers
If you want one treat rather than a multipack, check the stated weight as well as the bar format. The bars considered here include both 90g and 100g options.
Who is this for?
Shoppers choosing by cocoa taste
Dark bars in this selection range from a smoother 50% option to 100% cocoa. The percentage gives you a starting point, but the ingredients of the exact bar also matter.
Vegan shoppers and allergen-conscious households
A vegan recipe and allergy suitability are different questions. Some dark bars described as vegan also carry milk or nut warnings, so check the current wrapper for the person who will eat the bar.
What should you check?
Choose a cocoa profile you expect to enjoy, then compare the exact bar’s format and label rather than treating all dark chocolate as interchangeable.
| Priority | What to check | Your needs |
|---|---|---|
| Bar size | Check that it is a single bar, then compare the stated weight. The listed Joybuy options include 90g and 100g bars. | I want one bar and need to know how much chocolate I am choosing, rather than assuming similar-looking packs contain the same amount. |
| Cocoa intensity | Read the cocoa-solids percentage and the ingredient list. Around 70%, 74–85% and 100% cocoa represent different starting points for taste; the percentage alone does not describe every ingredient. | Around 70% appeals if I want some sweetness with the cocoa flavour. If I prefer a stronger cocoa taste, I can consider 74–85%; I would choose 100% only if I enjoy its intensity. |
| Ingredients and allergens | Check the current ingredients, allergen declaration and precautionary warnings on the exact wrapper. Do not use a vegan statement as a substitute for an allergy check. | I need to know whether the particular bar fits my ingredient preferences or whether its allergy warnings rule it out. |
| Product claims | Look for organic or Fairtrade wording on the particular bar, rather than extending a claim from one product across a brand’s range. | Those claims matter to me, so I want to check that they apply to the bar I am considering. |
Common buying mistakes
-
Choosing the largest cocoa percentage by default
A higher percentage changes the flavour choice; it does not make a bar suitable for every taste. The options considered range from a smoother 50% bar to 100% cocoa.
Start with what you enjoy eating. Consider around 70% for some sweetness with the cocoa flavour, 74–85% for a stronger cocoa taste, and 100% only if you want that particularly intense profile.

Assuming vegan means suitable for a milk allergy
Lindt describes its Excellence 70% bar as made to a vegan recipe but says it is not suitable for people with a milk allergy. Other researched dark bars also carry precautionary allergen warnings.
If an allergy is involved, read the current wrapper for the exact bar rather than relying on a vegan badge, retailer filter or earlier ingredient listing.
Brand references for single dark bars

Frequently asked questions
Should I choose 70%, 85% or 100% dark chocolate?
Choose around 70% if you want some sweetness with the cocoa flavour, or consider 85% if you prefer a stronger cocoa taste. Choose 100% only if you enjoy its particularly intense profile. Cocoa percentage alone does not establish the full ingredient list or allergy suitability.
Is vegan dark chocolate suitable for someone with a milk allergy?
Not necessarily. Lindt says its Excellence 70% bar is made to a vegan recipe but is not suitable for people with a milk allergy. Check the current allergen declaration on the exact bar rather than relying on vegan wording.
Should I read the wrapper if ingredients appear online?
Yes. M&S advises shoppers to read the product label rather than rely solely on online product information, which can change. Use the current wrapper to check ingredients and allergen information for the bar you intend to eat.
