What should you check before choosing?
Start with the flavour and pack format you want for a break, then check the current label for dietary requirements and any sourcing claims that matter to you.
| Priority | What to check | Your needs |
| Cocoa and flavour | Compare the stated cocoa percentage and whether the bar is plain or flavoured. Lindt and Divine list 70% bars; Montezuma's lists both 74% FitzRoy and 100% Absolute Black. | I want a plain bar, but I do not want to choose a higher cocoa percentage just because the number is bigger. |
| Ingredients and allergens | Read the current ingredients, allergen statement and any “may contain” wording for the exact bar. Do not use “dark” or “vegan” as an allergy-suitability statement. | Milk or another ingredient matters to me, so I need the pack information for the bar I am buying. |
| Pack and portion | Check the bar’s total weight and whether nutrition is stated per 100g or per serving. Decide whether you want to divide a full bar across breaks. | For one short break, I may want part of a bar rather than treating the whole pack as one portion. |
| Sourcing claims | Check which claims apply to the named product. Divine describes its 70% bar as containing Fairtrade ingredients; Montezuma's names FitzRoy Organic 74% in its dark range. | I would rather choose using a specific product claim than assume all dark chocolate has the same sourcing. |

Questions about revision-break chocolate
What cocoa percentage should I choose for a revision break?
If you are unsure whether you enjoy higher-cocoa chocolate, a plain bar around 70% to 74% is a starting point to consider. Lindt and Divine list 70% bars, while Montezuma's lists a 74% FitzRoy bar; the cocoa percentage does not establish a revision or health benefit.
Does a vegan dark-chocolate bar suit someone with a milk allergy?
Not necessarily. Lindt says its EXCELLENCE 70% bar is made to a vegan recipe but is not suitable for people with a milk allergy, and Divine says its vegan-labelled 70% bar may contain milk. Check the current pack for the exact product.
Is a 90g or 100g bar one serving?
The pack weight does not, by itself, define the amount to eat in one break. Check the product’s serving and per-100g information, then decide whether to divide the bar and store the remainder.
Do school-food rules apply to chocolate bought for personal revision?
The Department for Education’s cited school-food guidance addresses food and drink provided in state-funded schools in England; it should not be read as a UK-wide rule about a personal chocolate purchase. If a school is providing the snack, check the requirements and policy applicable to that school.
Can I rely on an online ingredient description?
Use it to compare products, but check the current pack before relying on ingredient, nutrition or allergen details. M&S advises shoppers to read the label because recipes and product information can change.
