Everyday top-up shoppers
If you want one bar rather than a multipack, compare cocoa percentage and weight alongside the flavour you expect. A 90g bar and a 125g bar are different quantities, even when both fit a top-up shop.
Who is choosing a single bar?
People who prefer intense cocoa
Montezuma’s describes Absolute Black as a 100% cocoa bar with no added sugar. It is worth considering if that unsweetened profile is what you want, rather than treating it as interchangeable with a 70% bar.
Shoppers checking ingredients or allergens
Fairtrade, organic and vegan-recipe descriptions answer different questions from an allergen statement. Check the particular bar’s current wrapper if an ingredient or possible cross-contact affects your choice.
What should you check?
Choose the cocoa profile and type of bar you want, then compare weight, ingredient claims and the current allergen statement.
| Priority | What to check | Your needs |
|---|---|---|
| Cocoa profile | Read the stated cocoa percentage and whether the bar has added sugar. Lindt describes its 70% bar as balanced; Montezuma’s Absolute Black is 100% cocoa with no added sugar. | I want a familiar dark-chocolate bar, not an unsweetened 100% cocoa bar. Or I already know that an intense cocoa profile is the point of this purchase. |
| Bar size | Compare the weight and format as well as the shelf price. The referenced Lindt 70% bar is 100g, Divine 70% is 90g and M&S Swiss Extra Fine Dark Chocolate is 125g. | One smaller bar is enough for my top-up, or I would rather pick up a larger bar. I need to check the quantity before comparing what I spend. |
| Allergens | Read the current ingredient and may-contain statements for the exact variant. Lindt says its vegan-recipe 70% bar is not suitable for a milk allergy; Divine and Montezuma’s also list possible milk cross-contact. | If I must avoid an allergen, the wrapper matters more than a general description such as “dark” or “vegan”. |
| Ingredient preferences | Look for the claim on the particular bar. Divine states that its 70% bar uses Fairtrade ingredients and is made without palm oil or soya; Tesco lists Green & Black’s Organic 70% bar as organic and Fairtrade. | Fairtrade sourcing, organic certification or a particular ingredient choice matters to me, so I want that attribute stated for the bar I buy. |
| Local purchase | Check the shop’s current stock information before a special trip. M&S directs shoppers to their local Foodhall for stock and price; Hotel Chocolat offers Find In Store and Click & Collect for its 70% slab. | I’m picking up a bar on a particular journey and need to know whether my chosen shop has it. |
What is easy to overlook?
-
Assuming dark or vegan-recipe chocolate is suitable for a milk allergy
Lindt says its EXCELLENCE Dark 70% bar is made to a vegan recipe but is not suitable for people with a milk allergy. Divine and Montezuma’s also state that their referenced bars may contain milk.
Use the current allergen statement for the exact bar to decide whether it meets your requirements.
-
Buying 100% cocoa as though it were an ordinary 70% bar
Montezuma’s Absolute Black is made from 100% cocoa mass with no added sugar, unlike the 70–72% bars considered for a more conventional dark-chocolate top-up.
Choose it if you specifically want an unsweetened cocoa profile; otherwise, compare the 70–72% options first.
-
Comparing bars without checking their weight
The referenced single bars range from 90g to 125g, so a shelf-price comparison alone does not compare equal quantities.
Check the grams and format alongside the displayed price before deciding which bar fits this purchase.
-
Treating an online listing as confirmation of local stock
M&S asks shoppers to check their local Foodhall, while Hotel Chocolat provides separate in-store and Click & Collect options.
Check availability for the shop you intend to visit before making a special trip.
If the bar is not there, you may need another journey or a different choice.

Lindt Excellence Orange Intense 100g
A 100g orange-flavoured dark bar if you want a flavoured option rather than the plain Lindt EXCELLENCE Dark 70% bar discussed above. Check this variant’s current cocoa percentage and allergen statement rather than applying the plain bar’s details to it.
No image available
Lindt Excellence 85% Cocoa Dark 100g
A 100g bar to consider if you specifically want 85% cocoa rather than a 70–72% option. Check its current allergen statement if you need to avoid nuts, milk, soya or sesame.
Common questions
Is a higher cocoa percentage always the right choice?
No. Lindt describes its EXCELLENCE Dark 70% bar as balanced, while Montezuma’s Absolute Black is a 100% cocoa bar with no added sugar. Choose the latter when you specifically want an unsweetened cocoa profile, not because its percentage is higher.
Does a vegan-recipe dark bar suit someone with a milk allergy?
Not necessarily. Lindt says its EXCELLENCE Dark 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 using milk. Check the current allergen statement for the exact bar.
Why check the wrapper when buying a familiar bar?
The wrapper gives the ingredient and allergen information for the bar you are buying. Check it rather than relying on a general brand description or assuming that a flavoured variant has the same ingredients as a plain bar.
How should I compare two single bars of different sizes?
Read the weight and displayed price together, then consider whether the bars have the same format and cocoa profile. A 90g bar and a 125g bar are different quantities, so the shelf price alone is not a like-for-like comparison.
Will an online listing mean the bar is in my local shop?
Not necessarily. M&S directs shoppers to check their local Foodhall for its Swiss Extra Fine Dark Chocolate, and Hotel Chocolat provides Find In Store and Click & Collect options for its 70% slab. Check the relevant shop’s current availability before a special trip.
