Who is this for?

Cyclists planning longer rides

You want portable food for a ride lasting more than about 90 minutes and need to distinguish a chocolate snack from the carbohydrate you plan to eat along the way.

Riders choosing a portioned treat

You enjoy dark chocolate before an easy ride, after riding or away from the bike, and want a bar size that makes your intended portion clear.

Shoppers comparing recipes and labels

You are considering vegan recipes or no-added-sugar chocolate and need to check carbohydrate, ingredients and possible allergen cross-contact on the exact bar.

What should you check?

Decide whether the bar is a treat or part of what you will carry on a ride, then compare the amount you intend to eat rather than the whole tablet.

Priority What to check Your needs
Ride fuel Check carbohydrate in the portion you will carry, not just per 100g. British Cycling advises eating from the start and every 20–30 minutes on rides over about 90 minutes. For a longer ride, I want to plan regular carbohydrate intake rather than count on a small piece of dark chocolate to provide it.
Portion and packing Compare a defined 35g bar with a larger tablet that needs breaking and wrapping. Divine lists its 35g 70% bars as a 30-bar pack; the individual bar size does not establish that they are sold separately. A small treat is easier to plan when I decide how much to take before leaving, rather than carrying an entire 90–125g tablet.
Nutrition panel Compare carbohydrate, sugars, fat and saturates per 100g and for your intended portion. NHS food-label guidance explains that nutrition information is given per 100g and may also appear per portion. If I am choosing between a conventional dark bar and 100% cocoa, I want to know what the amount I will actually eat contains.
Ingredients and allergens Read the exact bar’s current ingredients and allergen statement. A vegan recipe, no-added-sugar claim or cocoa percentage does not resolve possible cross-contact. I need the current wrapper to answer any dietary or allergy question, not just the description of the chocolate range.

What can trip you up?

  • Counting a whole tablet as one snack

    A 90–125g bar may be much more than the portion you meant to carry.

    Break and wrap your planned amount beforehand, then read the nutrition figures for that amount as well as per 100g.

  • Using 100% cocoa chocolate as your main long-ride fuel

    Montezuma’s lists 18g carbohydrate per 100g for Absolute Black 100%, while British Cycling’s long-ride guidance centres on regular carbohydrate intake.

    If you choose it for its taste or no-added-sugar recipe, plan your ride carbohydrate separately.

  • Assuming dark or vegan-recipe chocolate is allergy-safe

    Some of the listed bars carry possible milk, nut or other allergen cross-contact warnings despite their dark-chocolate or vegan-recipe descriptions.

    Check the current wrapper for the exact product each time you buy, particularly when you need to avoid an allergen.

Brand and range references

These examples show how bar format and declared nutrition differ; check the exact product rather than applying one range’s details to every bar from a brand.

Divine

Divine lists a 90g 70% bar and 35g 70% bars sold as a 30-bar pack.

  • The defined 35g size gives you a clear amount to portion; Divine declares 31.7g carbohydrate per 100g for its 70% chocolate.
  • The listed 70% products warn of possible milk, gluten and nut cross-contact.

Lindt

Lindt Excellence 70% is a 100g tablet that can be broken into a planned snack portion.

  • Lindt declares 34g carbohydrate and 41g fat per 100g for this bar.
  • Lindt lists possible nuts, milk, soya and sesame; check the label if any of these affect your choice.

Green & Black’s

Its Organic 70% dark chocolate is listed as a 90g bar.

  • Tesco lists 36g carbohydrate and 42g fat per 100g for this product, allowing comparison on the same basis as other bars.
  • The product declaration warns that it may contain nuts and milk; portion the 90g tablet to suit the amount you intend to eat.

Montezuma’s

The FitzRoy Organic 74% bar and Absolute Black 100% bar serve different taste and recipe preferences.

  • Montezuma’s declares 33g carbohydrate per 100g for FitzRoy 74%, compared with 18g per 100g for Absolute Black 100%.
  • Absolute Black’s lower carbohydrate figure makes it a poor choice as the main source of ride carbohydrate. Both listed products carry possible milk, nut and peanut trace warnings.

Hotel Chocolat

Its 70% Dark Chocolate Slab Selector is an option for shoppers choosing by chocolate format and flavour.

  • Check the exact slab’s current pack for weight, nutrition, ingredients and allergens before choosing a portion for a ride.

M&S

M&S lists a 125g Swiss Extra Fine 72% dark bar, distinct from its separate 70% baking chocolate.

  • The Swiss Extra Fine 72% bar declares 31.8g carbohydrate and 43.4g fat per 100g.
  • Its 125g size calls for advance portioning, and M&S lists milk, nut, peanut and soya allergy unsuitability for this product.

Common questions

Can dark chocolate replace ride food or a carbohydrate drink on a long ride?

Do not rely on a small dark-chocolate portion as your main carbohydrate source. British Cycling advises eating regularly from the start of rides over about 90 minutes; a 35g Divine 70% bar provides about 11g carbohydrate based on Divine’s declared per-100g figure. Plan the rest of your ride food and drink around the duration and demands of your ride.

When does a dark-chocolate bar fit a cycling day?

A portioned bar can be a treat before an easy ride, after riding or away from the bike. For a longer ride, British Cycling advises regular eating, so plan the carbohydrate you will carry separately rather than assuming chocolate will cover it.

Does 100% cocoa make a bar more useful for cycling?

Not if you want the bar to supply ride carbohydrate. Montezuma’s lists 18g carbohydrate and 0.6g sugars per 100g for Absolute Black 100%, while its FitzRoy 74% bar lists 33g carbohydrate per 100g. Choose between them for the recipe and flavour you want, while checking the amount you intend to eat.

Which figures should I compare on a dark-chocolate label?

Compare carbohydrate, sugars, fat and saturates per 100g, then work out what the portion you plan to eat represents. NHS food-label guidance notes that nutrition information is given per 100g and sometimes per portion; also read the current ingredients and allergen statement.

Does a vegan dark-chocolate recipe rule out milk or nut warnings?

No. Some of the listed dark-chocolate products describe a vegan recipe while carrying possible milk or nut cross-contact warnings. Check the current wrapper for the exact bar rather than treating the recipe description as an allergy statement.
