People packing a lunchtime treat
If you want to decide how much chocolate to carry, compare a standard bar with individually sized pieces. Check the whole pack size too: Divine’s 12.5g mini bars, for example, are sold in a pack of 160.
Who these choices suit
People who enjoy pronounced cocoa flavours
Compare the flavour you expect from 70–75% cocoa bars with the more intense 85–90% options. Cocoa percentage alone does not tell you the bar’s sugar, saturated fat or energy values.
People checking ingredients and allergens
Read the exact product’s current ingredients and allergy statements, including any “may contain” warning. A dark-chocolate description or vegan recipe is not enough to establish suitability for a milk allergy.
What to check before buying
Choose a flavour and pack format you will use, then compare labels on the same per-100g basis before deciding what portion to carry.
| Priority | What to check | Your needs |
|---|---|---|
| Portion and pack | Check the weight of a bar or individual piece, how many pieces the pack contains and whether you can take only the amount planned. | I want to pack a small amount without carrying a whole bar. If I buy mini bars, the total pack size needs to suit how often I will use them. |
| Cocoa flavour | Compare the declared cocoa percentage and ingredients of the exact bar. Lindt Shop UK lists 70% and 90% Excellence bars with different sugar values: 29g and 7g per 100g respectively. | A stronger cocoa flavour appeals to me, but I do not want to choose a percentage without considering whether I will enjoy the bar. |
| Nutrition label | Compare sugars, saturates and energy per 100g, then consider the portion you intend to eat. The NHS defines more than 5g saturates per 100g as high; cocoa percentage is not a substitute for checking that figure. | I want to compare bars on the same basis rather than assume that darker chocolate has lower values across its nutrition panel. |
| Allergen information | Read the current ingredients, allergy advice and precautionary warnings for the exact product. The Food Standards Agency explains that “may contain” labelling communicates possible unintended allergen presence. | If an allergen matters to me, I need the pack’s specific warning, not an assumption based on “dark” or “vegan”. |
Common buying mistakes
-
Assuming more cocoa means less saturated fat
The NHS defines more than 5g saturates per 100g as high. Lindt Shop UK lists 24g per 100g for its Excellence 70% bar and 30g for its 90% bar.
Use cocoa percentage to guide your flavour choice, but compare saturates, sugars and energy per 100g separately.
-
Treating “vegan” or “dark” as an allergy guarantee
Lindt describes its Excellence 90% bar as made to a vegan recipe but says it is not suitable for people with a milk allergy. Other dark bars also carry product-specific allergy warnings.
Check the current pack, including “may contain” statements, against the allergens relevant to you.
-
Buying mini bars without checking the full pack
Individually sized pieces can make a planned portion straightforward, but Divine’s 12.5g mini bars come in a pack of 160.
For occasional lunches, compare that commitment with a standard bar or a smaller pack.
A 160-bar pack also needs storage space and a plan for using the remaining bars.
-
Letting the chocolate bar stand in for lunch
The British Dietetic Association’s snack guidance notes that chocolate can add fat and sugar and advises keeping snack portions sensible.
If you take chocolate for a lunchtime treat, plan the rest of your lunch separately rather than relying on the bar alone.
Brand ranges to compare
These brand references describe particular ranges and formats, not every product each brand makes or the products available in the Joybuy list below.
Green & Black's
Green & Black’s identifies a 70% dark chocolate 90g bar on its UK site.
- A standard bar format to consider when you plan to take part of a bar.
- Check the exact pack for the nutrition and allergen details relevant to your purchase.
Divine
Divine lists a 70% dark chocolate 90g bar and 12.5g mini bars.
- The individually sized mini bars offer a predetermined amount to pack.
- The mini-bar listing is for 160 bars, rather than a single lunchtime piece.
Lindt
Lindt Shop UK lists Excellence 70% and 90% dark chocolate bars at 100g each.
- Their published per-100g panels allow a like-for-like comparison: the 70% bar lists 29g sugars and 24g saturates, while the 90% bar lists 7g sugars and 30g saturates.
- Both product pages include possible-allergen warnings; check the current pack before buying.
Montezuma's
Montezuma’s lists a FitzRoy Organic 74% dark chocolate bar and Absolute Black 100% cocoa options.
- The range gives shoppers different declared cocoa percentages to consider.
- Check the format of the exact product: its 74% couverture listing is a cooking format, not a portable bar.
Hotel Chocolat
Hotel Chocolat lists 70% dark chocolate batons alongside higher-cocoa options.
- The baton format offers an alternative to a standard bar.
- For the 70% batons, check the current pack or full product information if ingredients, nutrition or allergens affect your choice.
M&S
M&S lists 75% single-origin and 85% dark chocolate bars with nutrition information.
- M&S lists 25.5g sugars per 100g for its 75% bar and 15.9g for its 85% bar.

Morrisons The Best Ecuador 85% Dark Chocolate 100g
This 85% cocoa standard bar is another option if pronounced cocoa flavour matters more to you than a pre-portioned format. Check its current pack for warnings about possible gluten-containing cereals, milk, nuts and peanuts.

Green & Black's Dark 70% Chocolate 90g
This 70% cocoa bar offers a standard format from which to pack a planned amount. Check the current pack for warnings about possible almonds, hazelnuts, other nuts and milk.

Divine 70% Dark Chocolate with Raspberries 90g
This 70% cocoa bar is a fruit-flavoured option if you want to pack part of a standard bar. The listing’s vegan-friendly wording conflicts with its milk information; check the current pack rather than relying on that claim for dietary or allergy suitability.
Frequently asked questions
Is an 85–90% bar automatically a better lunchtime choice?
No. Choose that range if you enjoy its more intense cocoa flavour or want to compare the listed sugars, but check the rest of the label too. Lindt Shop UK lists 7g sugars and 30g saturates per 100g for its Excellence 90% bar; M&S lists 15.9g sugars and 30.5g saturates per 100g for its 85% bar.
Can a dark chocolate bar replace lunch?
Plan it as a treat alongside lunch rather than relying on the bar alone. The British Dietetic Association’s snack guidance advises planning ahead and keeping portions sensible, noting that chocolate can add fat and sugar.
Does a vegan recipe mean a bar is suitable for a milk allergy?
No. Lindt says its Excellence 70% and 90% bars are made to a vegan recipe but are not suitable for people with a milk allergy. Read the current allergy information for the exact bar.
What does “may contain” mean on a chocolate label?
It warns that an allergen could be unintentionally present. The Food Standards Agency describes precautionary allergen labelling as communicating this cross-contact possibility; check the current product label when an allergy is relevant.
How should I carry dark chocolate in a bag?
Keep it cool, dry and out of sunlight where practical. M&S gives those storage directions for its dark chocolate bars; follow the instructions on the pack you buy.
