Who is this choice for?

Shoppers wanting a plain break-time treat

If filled or flavoured chocolate is not what you want during a short break, start by comparing plain bars. A bar around 70% to 74% cocoa is one option if you have not established a preference for higher-cocoa chocolate; the percentage alone cannot tell you whether you will enjoy its flavour.

Shoppers with dietary requirements

Check the exact bar’s current ingredients and allergen wording. Lindt says its EXCELLENCE 70% bar is made to a vegan recipe but is not suitable for people with a milk allergy; Divine’s vegan-labelled 70% bar says it may contain milk.

Shoppers interested in sourcing claims

If sourcing affects your choice, look for a claim attached to the particular bar rather than assuming it applies to every product from a brand. Divine describes its 70% bar as using Fairtrade ingredients and says its company is cocoa-farmer co-owned.

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.

PriorityWhat to checkYour needs
Cocoa and flavourCompare 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 allergensRead 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 portionCheck 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 claimsCheck 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.

Common buying mistakes

  • Assuming dark or vegan chocolate is allergy-safe

    Recipes and cross-contact statements differ. Lindt says its vegan-recipe EXCELLENCE 70% bar is not suitable for people with a milk allergy, while Divine’s vegan-labelled 70% bar may contain milk.

    Check the current pack’s ingredients and allergen statement for the exact bar and your particular requirement.

  • Choosing by cocoa percentage alone

    The percentage identifies a recipe characteristic, not whether you will like the bar or whether it will help you revise. Montezuma's, for example, lists both a 74% FitzRoy bar and a 100% cocoa option.

    If you are unsure about a higher-cocoa bar, compare a plain option around 70% to 74% with the flavours you already enjoy.

  • Treating the whole bar as one break-time portion

    A 90g or 100g pack is a full bar, not an instruction to eat it in one sitting. Nutrition information may also use a different reference amount from the pack weight.

    Check the weight and serving information, then decide how much you want for the break and store the remainder as directed on the pack.

  • Applying school-food guidance to every personal snack

    The Department for Education’s school-food guidance concerns food and drink provided in state-funded schools in England. That scope is different from choosing a bar for a personal revision break.

    If chocolate is being provided through a school meal, snack service or event, check the applicable school-food requirements and the school’s policy rather than assuming the rules for a personal purchase are identical.

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.
