Choosing dark chocolate: how to compare cocoa percentage, flavour and quality

Want to order dark chocolate, but finding it hard to tell the difference between all the percentages and marketing claims? A bar with 70% cocoa doesn’t automatically taste the same as a 70% bar from another brand. Terms such as ‘intense’, ‘premium’ and ‘dark’ also tell you little about the ingredients unless you check the list.

Most disappointing purchases come down to three common pitfalls:

  • Looking only at the cocoa percentage: a higher percentage usually means less sugar, but it can also give the chocolate a stronger, more bitter flavour.
  • Confusing dark chocolate with plain chocolate: some bars contain milk powder, milk fat or a soft filling. Always check the ingredients.
  • Underestimating added flavours: caramel, orange, nuts or matcha can significantly change the flavour and add extra allergens.

Which dark chocolate features matter?

1. Check the cocoa percentage

The percentage tells you how much of the bar is made up of cocoa ingredients. A 70% dark chocolate bar will generally leave more room for sugar than an 85% dark chocolate or 90% dark chocolate bar. You can often taste the difference:

  • 70%: more approachable, with a clear but less pronounced bitter cocoa flavour.
  • 78–85%: stronger and less sweet, suited to those who enjoy dark chocolate.
  • 90%: very intense, with little sugar and a pronounced cocoa character.

Be sure to check the exact packaging. The product information for Tony’s Chocolonely Pure 70% states both ‘at least 70%’ and a different figure in another section. Always check the current packaging and ingredients list before buying.

2. Check the ingredients, not just the front of the pack

A dark chocolate bar often contains cocoa mass, cocoa butter and sugar. Other ingredients can change its texture and flavour. Look out in particular for:

  • Milk powder or milk fat: important if you want to avoid dairy ingredients.
  • Soya or sunflower lecithin: often used as an emulsifier.
  • Nuts, almonds or sesame: important if you have an allergy or intolerance.
  • Fillings and crunchy pieces: can increase the sugar and calorie content.

For example, the product information for Lindt Excellence 85% lists cocoa mass, low-fat cocoa, cocoa butter, brown sugar and vanilla. According to the information provided, the bar contains at least 85% cocoa. Lindt Excellence 90% contains, among other ingredients, cocoa mass, cocoa butter, low-fat cocoa powder, sugar and vanilla, according to the product description.

3. Compare weight and nutritional values per 100g

A 100g bar isn’t automatically better value than a 180g or 220g bar. Compare the price per 100g instead. Also check the nutritional values, especially when comparing different varieties.

Lindt Excellence 85% (100g) lists 584 kcal, 46g of fat, 19g of carbohydrates and 11g of sugars per 100g. Lindt Excellence 90% lists 592 kcal, 55g of fat, 14g of carbohydrates and 7g of sugars per 100g. These figures make the difference between the two varieties clear, but they don’t tell you everything about the flavour or whether either bar is right for every shopper.

Flavoured varieties can differ considerably too. According to the product information, Lindt Excellence Dark Caramel & Sea Salt contains at least 47% cocoa solids and 54g of sugar per 100g. Its ingredients therefore put it in a different category from 85% or 90% dark chocolate.

How to store and use dark chocolate

Store chocolate in a cool, dry place, away from direct sunlight, heat and moisture. The product information for the bars mentioned also recommends resealing the pack securely after opening. A white bloom can appear on chocolate after temperature changes, but if you’re unsure, always check the packaging and best-before date.

Dark chocolate naturally contains stimulants such as caffeine and theobromine. If you’re sensitive to these, you may want to adjust your portion size and when you eat it. This is general product information, not health advice.

Frequently asked questions about dark chocolate

Is dark chocolate with 70% cocoa always less sweet than milk chocolate?

Not necessarily to the same degree. A higher cocoa percentage generally leaves less room for sugar, but check the nutritional values per 100g. A bar with caramel or a filling can still contain relatively high levels of sugar, despite having a dark chocolate base.

Which dark chocolate is suitable for baking?

A simple bar with 70% to 85% cocoa is often a practical choice for ganache, desserts and chocolate sauce. If you want a smooth result, check that the bar doesn’t contain nuts, caramel or other pieces. A larger pack, such as 180g, can be handy when you’re making several portions.

How long does dark chocolate keep?

Check the date on the packaging. Keep the bar sealed, somewhere dry and away from direct sunlight. Shelf life varies by product, so always use the information on the packaging as your guide.
