How to choose dark chocolate: comparing cocoa percentage, flavour and ingredients

Buying dark chocolate seems simple: pick a bar, check the cocoa percentage and add it to your basket. Yet chocolate bars vary greatly in flavour, composition, allergens and when you might enjoy them. A bar with 70% cocoa, for example, isn't automatically comparable to a 70% variant with nuts, caramel or extra filling.

As a Joybuy Product Recommendation Officer, I filter product information by practical points. This helps you see more quickly which dark chocolate suits your taste, and stops you from relying solely on packaging or marketing copy.

Common pitfalls with dark chocolate

1. Only looking at the cocoa percentage

A higher percentage usually means less sugar in the chocolate, but it doesn't tell you everything about the flavour. Dark chocolate 85% or dark chocolate 90% can be noticeably more bitter and intense than dark chocolate 70%. The ingredients used, the texture and the amount of cocoa butter also affect the experience.

Always check the ingredients list and nutritional values per 100 grams. For example, Lindt Excellence 90% lists 7 grams of sugar per 100 grams, while Lindt Excellence 70% contains 29 grams of sugar per 100 grams. That's a clear difference within the same brand.

2. Confusing "dark" with a high cocoa percentage

Not every bar labelled "dark chocolate" contains 70% cocoa or more. According to the product information, Tony's Chocolonely Pure Almond Sea Salt contains a minimum of 51% cocoa solids. The bar combines dark chocolate with almonds and sea salt, which makes the flavour less one-dimensional than a plain dark chocolate bar.

So read the exact percentage on the packaging. Words like "intense", "rich" or "premium chocolate" are no substitute for verifiable product data.

3. Skipping additions and allergens

Chocolate with nuts, orange, caramel or sea salt can be appealing, but additions change the nutritional values and allergen information. In particular, check for milk, soya, nuts, almonds, sesame and gluten. Product information can also change; if you have an allergy, always use the current packaging as your guide.

Which specifications are important?

Cocoa percentage and sugar

Use the percentage as a first filter:

  • 70% cocoa: often an accessible starting point for those wanting to learn to appreciate dark chocolate.
  • 78% to 85% cocoa: typically a more powerful cocoa flavour with less sugar.
  • 90% cocoa: suitable for lovers of a pronounced, less sweet taste.
  • 51% cocoa: can suit those looking for dark chocolate with extra ingredients and a softer flavour profile.

The cocoa percentage doesn't tell you how much you should ideally eat. Dark chocolate naturally contains caffeine and theobromine. If you're sensitive to stimulants, it's wise to limit your consumption. When in doubt, follow the information on the packaging.

Ingredient order

Ingredients are listed in descending order by weight. If sugar appears early in the list, it forms a relatively large part of the product. With a simple bar, you'll often see cocoa mass, sugar and cocoa butter. With filled or composite snacks, ingredients like dates, almonds, milk powder, syrups or vegetable fats are added.

A short ingredients list makes comparing easier, but it doesn't automatically mean the flavour will suit you. Also look at the desired texture: a thin tablet melts differently to a bar with nuts or a soft filling.

Portion, packaging and storage tips

A 100-gram bar is handy for breaking into squares. Larger 180-gram bars are suitable for sharing or for several snacking occasions. Store chocolate in a cool, dry place, out of direct sunlight and away from heat and moisture. Seal the packaging well after opening. Check the best-before date upon receipt and do not use damaged packaging.

Frequently asked questions about dark chocolate

Is 70% dark chocolate a good choice for beginners?

70% dark chocolate is often a practical starting point because the cocoa flavour is clearly present without the intensity of 85% or 90%. Do compare the sugar content and the ingredients. Two bars with the same percentage can taste different due to recipe and additions.

What is the difference between dark chocolate and plain chocolate?

The terms are often used interchangeably in shops. The relevant difference is found on the label: the percentage of cocoa solids, the amount of sugar and the presence of milk solids. Also check whether the product is a standard tablet, chocolate with nuts or a composite chocolate snack.

How should you store dark chocolate to keep it fresh for longer?

Store the bar sealed in a cool, dry place, out of direct sunlight and away from heat. The fridge is usually not necessary and can affect the texture due to moisture and odour differences. Always refer to the best-before information on the packaging.
