Choose dark chocolate by the cocoa flavour you enjoy, then compare the sugar and allergen information on the exact bar rather than assuming the highest cocoa percentage is the right choice. Lindt’s UK labels list 29g sugars per 100g for its 70% bar, 15g for its 85% bar and 7g for its 90% bar; if caffeine affects your sleep, Worcestershire Acute Hospitals NHS Trust’s sleep guidance identifies chocolate as a food to consider before bedtime.
If you want a square or two late in the evening, flavour and timing both matter. Worcestershire Acute Hospitals NHS Trust lists chocolate among caffeine-containing foods in its sleep guidance, which is relevant if caffeine keeps you awake.
If you are moving towards a more pronounced cocoa flavour, compare labels as well as percentages. Lindt’s UK labels list 29g sugars per 100g at 70%, 15g at 85% and 7g at 90%; those figures describe those particular bars, not every brand.
A vegan description and an allergen warning answer different questions. Check the exact pack for ingredients and precautionary statements: the Food Standards Agency explains that these statements communicate possible unintended allergen presence.
Start with the flavour you would enjoy in a small portion, then read the nutrition and allergen information for that specific bar.
| Priority | What to check | Your needs |
|---|---|---|
| Cocoa and sweetness | Compare cocoa percentage and sugars per 100g on the exact bars. Lindt’s UK labels list 29g sugars at 70%, 15g at 85% and 7g at 90%. | I want a cocoa flavour I will enjoy without choosing a sweeter bar than I intended. |
| Bedtime timing | Consider when you plan to eat it. Worcestershire Acute Hospitals NHS Trust lists chocolate among caffeine-containing foods in its sleep guidance. | If caffeine tends to keep me awake, I would rather have chocolate earlier or choose something else late at night. |
| Allergens and diet | Read the current pack’s ingredients and may-contain statement. A vegan description does not replace an allergy check; warnings differ between bars. | I need to distinguish my dietary preference from any allergen precautions that apply to me. |
| Portion and nutrition | Check the portion you intend to eat, then compare energy and saturates alongside sugars, using the same per 100g basis. Montezuma’s lists 623 kcal and 32g saturates per 100g for Absolute Black. | Lower sugar alone does not tell me how the bar compares on energy or saturated fat. |
A very high-cocoa bar can taste markedly bitter. Montezuma’s lists 623 kcal and 32g saturates per 100g for its 100% Absolute Black bar, despite its 0.6g sugars per 100g.
Choose a cocoa strength you expect to enjoy, then compare sugars, energy and saturates on the exact labels.
A product can have a vegan recipe and still carry a milk warning. Lindt says its 85% bar is made in a facility using milk and is not suitable for people with a milk allergy.
If an allergy matters to you, check the current pack’s allergen and may-contain statements rather than relying on a dietary description.
Worcestershire Acute Hospitals NHS Trust identifies chocolate among caffeine-containing foods in its sleep guidance and says caffeine effects can take seven to eight hours to wear off.
If caffeine has affected your sleep before, consider having chocolate earlier instead of immediately before bed.
The pack you receive is the one that matters when ingredients or allergen warnings affect your choice.
Before eating, check its ingredient list, nutrition panel, allergen statement and best-before date.
These ranges offer different cocoa strengths and formats; compare individual bars rather than assuming a characteristic applies across a brand.
The EXCELLENCE range offers several steps in cocoa strength, including 70%, 85% and 90% bars.
Divine offers an 85% dark bar and describes its business as co-owned by cocoa farmers.
An 85% dark bar is an option for buyers who want a high-cocoa bar with vanilla in its flavour description.

The dark range includes plain batons and mixed formats for buyers interested in different flavours or sharing.

Consider this bar if you want an 85% cocoa option and like a vanilla note alongside the cocoa flavour. Check the current pack’s allergen warning before eating, especially if milk or nuts matter to you; cocoa strength does not establish how chocolate will affect your sleep.

Check the cocoa percentage on the pack before choosing this bar for a particular flavour strength: its product title says 85%, while accompanying product information describes 72%. Read the current allergen declaration if milk, nuts, peanuts, gluten or soya matter to you.
No: the cocoa flavour you enjoy and the exact nutrition label both matter. Lindt’s UK labels list 15g sugars per 100g for its 85% bar and 29g for its 70% bar, but that comparison does not decide which flavour you will prefer or how late-night chocolate affects your sleep.
Not necessarily. Lindt lists 592 kcal and 30g saturates per 100g for its 90% bar, while Montezuma’s lists 623 kcal and 32g saturates per 100g for Absolute Black. Compare energy and saturates as well as sugars on the bars you are considering.
Consider eating it earlier or choosing another late-night snack. Worcestershire Acute Hospitals NHS Trust identifies chocolate among caffeine-containing foods in its sleep guidance; a cocoa percentage alone cannot tell you how an individual bar will affect your sleep.
A vegan description does not establish that. Lindt says its 85% bar is made to a vegan recipe but is not suitable for people with a milk allergy because it is manufactured in a facility using milk. Check the exact current pack’s allergen statement.
Choose 100% cocoa only if you want its pronounced, unsweetened cocoa flavour. Montezuma’s describes Absolute Black as having no added sugar, but its label also lists 623 kcal and 32g saturates per 100g; if caffeine affects your sleep, consider the timing of chocolate as well as its cocoa strength.
