For a night-shift treat, a 70–75% cocoa bar is a starting point if you prefer some sweetness; consider 85% or above if you already enjoy a stronger, less sweet cocoa flavour. Compare the sugar information and your intended portion on the current pack, and check its allergen warnings. A chocolate bar is an optional snack, not a way to manage shift-work fatigue.
A single bar is easy to take to a break, but choose its flavour and portion for enjoyment rather than expecting it to counter tiredness. The Health and Safety Executive identifies sleep loss and fatigue as significant issues for shift workers.
If you are unsure about a bitter cocoa flavour, compare a 70–75% bar with higher-cocoa options before choosing what to take on shift. Cocoa percentage does not tell you everything about a bar’s ingredients or nutrition.
Read the exact bar’s ingredients and precautionary warnings. A vegan recipe does not remove a “may contain” warning for milk or other allergens.
Choose a cocoa intensity you expect to enjoy, then compare the portion, nutrition information and allergen statement for the exact bar.
| Priority | What to check | Your needs |
|---|---|---|
| Cocoa flavour | Compare cocoa percentages and whether the bar is plain, flavoured or filled. Do not assume a higher percentage will suit your taste. | I would rather enjoy a bar during my break than choose the highest cocoa percentage for its own sake. |
| Sugar and portion | Read sugars per 100g alongside the bar weight and any per-serving figures. Lindt Shop UK lists 29g sugars per 100g for Excellence 70% and 7g per 100g for Excellence 90%; those figures describe those two bars, not every bar at those percentages. | If I plan to eat only part of the bar, I want to compare the nutrition information with that portion rather than treat the whole bar as one serving. |
| Allergens | Check the current ingredients and “may contain” statement for the exact variant, including on bars described as vegan. Lindt Shop UK lists nuts, milk, soya and sesame in the precautionary information for its Excellence 70% bar. | Where I need to avoid an allergen, the warning on the bar I buy matters more than a general description of the range. |
| Shift timing | Consider when your planned sleep begins and your own sensitivity to stimulants. Keep a snack separate from your arrangements for meals, breaks and rest. | For a break close to bedtime, I want a treat that fits my plans without relying on chocolate to keep me alert. |
A higher cocoa percentage changes the flavour, but it does not establish that a bar will suit your taste or intended portion. Sugar figures also need comparing on the exact products.
Start with a percentage you expect to enjoy, then read the bar’s nutrition panel rather than choosing by cocoa percentage alone.
A bar made to a vegan recipe can still carry a precautionary milk warning. Other warnings vary between products.
If you need to avoid an allergen, check the current pack’s ingredients and precautionary statement for that specific bar.
Hotel Chocolat describes its Better Way Bar as 70% dark chocolate with praline, biscuit and cherry. Those additional ingredients make it a different choice from plain dark chocolate.
Compare the complete ingredients, nutrition and allergen information before switching between plain and filled bars.
These examples show why the exact bar matters more than a brand name when comparing cocoa percentage, sugar and allergens.
Divine’s 85% dark chocolate comes as a 90g bar.
The Excellence range includes 70% and 90% dark chocolate in 100g bars.

Its 75% Cocoa Single Origin Dark Chocolate offers a percentage between the 70% and 85% examples discussed here.

The brand identifies a Dark 70% Chocolate 90g Bar.

The 70% cocoa bar is an option if you want to start below the more intense 85% choices. Check the pack’s nutrition information for the portion you intend to take on shift, and read its allergen statement.

At 72% cocoa, this bar offers another choice within the 70–75% range if you are deciding how intense a dark-chocolate flavour to try. Compare the nutrition information with your intended portion and check the pack’s allergen statement.

Consider this 85% cocoa bar if you already enjoy a stronger cocoa flavour. Its 90g weight describes the whole bar, not the portion you have to eat; check the current nutrition and allergen information when planning your break.

This 85% cocoa bar is worth considering if a pronounced cocoa flavour appeals to you. Before taking the 100g bar to work, decide on a portion and check the pack’s nutrition and allergen details.

The 85% cocoa level makes this a choice for someone who already likes a more intense dark-chocolate flavour. Check the current pack to compare nutrition for your intended portion and to distinguish ingredients from precautionary allergen warnings.
Try a 70–75% bar if you are unsure whether you enjoy a bitter cocoa flavour; consider 85% or higher if you already know that you do. Choose 100% cocoa only if you want an unsweetened taste. For sugar comparisons, use the exact bars’ per-100g nutrition figures rather than assuming every product at a given cocoa percentage is alike.
A vegan recipe alone does not establish milk-allergy suitability. Lindt’s Excellence 70% listing, for example, includes milk in its precautionary allergen information. Check the current pack for the specific bar and follow your allergy advice when deciding what to avoid.
Do not rely on a chocolate bar to manage fatigue. The Health and Safety Executive identifies sleep loss and fatigue as significant problems for shift workers; a bar can be an optional break-time snack, not a substitute for appropriate rest or fatigue controls.
