ÖKO-TEST’s December 2024 analysis of 21 dark chocolate samples revealed no ‘very good’ ratings, with five products rated ‘good’ and four organic options included. Notably, Lindt received a disappointing grade of 6 due to mineral oil residues and poor corporate social responsibility practices. Tony’s Chocolonely 70% emerged as the best conventional option, while Lidl’s Fairglobe Organic Chocolate performed well in the organic category. The evaluation included rigorous testing for harmful substances and assessments of ethical sourcing practices.
ÖKO-TEST’s Latest Findings on Dark Chocolate
In its December 2024 issue, ÖKO-TEST conducted a thorough analysis of dark chocolate, purchasing a total of 21 samples from various retail outlets including supermarkets, discount stores, organic markets, and drugstores. The chocolates examined boasted a cocoa content ranging from 66% to 75%, with ten of the products being certified organic.
The evaluation process involved a meticulous laboratory analysis of ingredients, alongside an assessment of the corporate social responsibility (CSR) practices of the chocolate manufacturers. CSR refers to the obligation of companies to act ethically and sustainably, impacting their communities and the environment. For this chocolate assessment, ÖKO-TEST sought proof of transparent supply chains, corporate due diligence, and commitments to address critical issues such as child labor, occupational safety, fair working conditions, and environmental conservation in the countries where the cocoa is sourced. Details on the specific testing and evaluation methods used by ÖKO-TEST can be found later in this article.
Lindt Chocolate Scores a Disappointing Grade
Out of the 21 dark chocolates tested, not a single product achieved a ‘very good’ rating. Five chocolates earned a ‘good’ rating, with four of those being organic. Seven others were deemed ‘satisfactory’, while five barely met expectations with a ‘sufficient’ rating.
Unfortunately, four dark chocolates did not pass the test, with two receiving a grade of 5, including an organic option from dm. Two others were given a lackluster grade of 6, notably including the renowned brand Lindt. The disappointing ratings were attributed to issues such as the presence of mineral oil residues and inadequate CSR practices. It is particularly concerning that well-known brands do not prioritize fair labor, safety, and environmental protection.
Top Performer in Dark Chocolate with High Cocoa Content
Among conventional chocolates, the standout product was Tony’s Chocolonely 70% dark chocolate, which received a ‘good’ rating. While traces of mineral oil and pesticides were detected, they were found in minimal quantities.
In the organic category, four chocolates also achieved ‘good’ ratings. Interestingly, one inexpensive option from Lidl, the Fairglobe Organic Chocolate Bitter with 70% cocoa, was among the top performers at only around 1.40 euros for 100 grams.
For perspective, the conventional winner, Tony’s Chocolonely, is priced higher, showcasing a significant difference in cost.

ÖKO-TEST’s Methodology for Evaluating Dark Chocolate
ÖKO-TEST procured 21 dark chocolates with cocoa content ranging from 66% to 75%, including ten that were certified organic. The prices for 100 grams of chocolate varied from 1.19 to 6.41 euros across different sales channels.
To ensure the quality of the chocolates, several laboratories conducted analyses. They compared the actual contents of sugar, fat, cocoa butter, and declared cocoa content against the labels, revealing no discrepancies. Additionally, tests for harmful substances, including mineral oil hydrocarbons, pesticides, and heavy metals were performed, with only two products exceeding the acceptable germ count.
Chocolates claiming to contain (Bourbon) vanilla, vanilla extract, or natural vanilla flavor were examined for the authenticity of the vanilla used, which all confirmed as genuine. No significant findings related to acrylamide, polycyclic aromatic hydrocarbons, ochratoxin A, or aflatoxin were reported. Expert sensory analysts evaluated the chocolates based on taste, aroma, and texture, finding no critical deviations. They also verified the accuracy of flavor declarations on the packaging, ensuring the Nutri-Scores were calculated correctly.
Finally, the experts sought detailed information about the sourcing practices for the cocoa beans used in the chocolates. They distributed a comprehensive questionnaire to all suppliers to evaluate their knowledge of the cocoa supply chain, adherence to corporate due diligence, and accountability for potential risks. Questions included whether child labor was effectively monitored, and whether suppliers were developing strategies for living wages and banning hazardous pesticides, along with evidence of deforestation bans over the past seven years. Points were awarded only if suppliers furnished proof of these efforts regarding the batch tested by ÖKO-TEST.
