For a first high-cocoa bar, a plain 70% option is a starting point: M&S Food describes higher cocoa percentages as generally more intense and less sweet, while Montezuma's presents 70% as an approachable introduction. If you already prefer a stronger cocoa flavour, consider a higher percentage, but compare bar weights and offer conditions before buying several. Check the exact pack's ingredients and allergen warnings regardless of whether a recipe is described as vegan.
Who is this for?
First-time high-cocoa buyers
If you are moving from milk chocolate, a plain 70% bar lets you explore a darker flavour before choosing a higher percentage. Montezuma's describes 70% as an approachable starting point; taste will still depend on the recipe.
Regular dark-chocolate shoppers
If you buy bars often, compare their weights on the same basis. Check how many bars a multibuy requires and whether its terms apply to the variety you want.
Ingredient- and allergen-conscious buyers
If an ingredient or allergen affects your choice, read both the ingredient list and any “may contain” warning on the current pack. A vegan recipe does not establish suitability for a milk allergy.
What should you check?
Choose a cocoa strength you expect to enjoy, then compare the exact bars and purchase conditions rather than relying on the percentage alone.
| Priority | What to check | Your needs |
| Cocoa strength |
Read the stated cocoa-solids percentage. Compare plain recipes if you want to judge cocoa flavour without added flavours. |
I'm trying high-cocoa chocolate for the first time, so I'd start around 70%; if I already prefer a more intense, less-sweet bar, I'd consider a higher percentage. M&S Food describes that general flavour difference, not a guarantee for every recipe. |
| Bar and offer size |
Compare weights using the same per-100g basis. Check the required quantity, eligible varieties and stock conditions for a multibuy. |
For one bar, I don't want an offer that requires several. If I'll use the full quantity, I can check whether my chosen variety qualifies. |
| Delivery |
Check delivery terms at checkout, including any minimum-order condition, especially for a small online order. |
I'm ordering only a bar or two and need to know the delivery terms before committing. |
| Ingredients and allergens |
Read the current pack's ingredient list and precautionary warnings. Check the exact variety rather than applying one bar's label to a whole range. |
If I avoid milk, nuts or another ingredient, a vegan description alone won't answer whether this particular bar meets my needs. |
| Sourcing claims |
Look for organic or Fairtrade claims on the exact product. Check product-specific claims about palm oil or soya against its current ingredients. |
Those attributes matter to me, but I still want a cocoa strength and bar format I'll use. |
Common buying mistakes
-
Choosing the highest cocoa percentage straight away
M&S Food describes higher-percentage chocolate as generally more intense and less sweet; a bar that tastes too bitter to you may go unused.
Try one plain bar around 70% before buying several higher-cocoa bars.
-
Overlooking weight and multibuy conditions
Bars come in different sizes, and a multibuy requires you to take the stated quantity. Lindt says its selected-bar offer is subject to stock availability.
Compare the same weight basis, confirm that your variety qualifies and check delivery terms for the order you intend to place.
-
Equating a vegan recipe with allergen suitability
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.
Read the current pack's ingredients and “may contain” statements for the exact bar.
-
Assuming a supermarket listing is the same everywhere
M&S says availability can vary by selected store and product information can change.
Check your local listing and the physical pack when choosing an M&S bar.

Frequently asked questions
Does a higher cocoa percentage mean I will prefer the bar?
No. M&S Food describes higher-percentage chocolate as generally more intense and less sweet, but preference depends on your taste and the recipe. If you are new to high-cocoa bars, try one around 70% before buying several at a higher percentage.
How can I compare different bar sizes and multibuys?
Use the same per-100g basis for bars of different weights, then check the quantity an offer requires and any delivery terms. Lindt says its selected EXCELLENCE-bar offer is subject to stock availability, so confirm that the variety you want qualifies.
Does a vegan label mean dark chocolate is suitable for a milk allergy?
No. 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 that uses milk. Read the current label for the exact bar.
What does “may contain milk or nuts” mean?
It is a precautionary warning that an allergen could be unintentionally present through cross-contact, as explained by the Food Standards Agency. It is different from listing an allergen as an ingredient; check the current pack if you need to avoid one.
