Stiftung Warentest has been a trusted source for consumer guidance for decades, known for its rigorous product evaluations. A recent investigation revealed that bamboo cups often contain melamine, which can pose health risks at high temperatures. The organization, founded in 1964 to counter corporate advertising, maintains independence in its assessments, relying solely on test report sales. With a strong reputation, it continues to address sustainability and safety concerns, helping consumers make informed choices.
For many years, consumers have turned to Stiftung Warentest for reliable guidance in their purchasing choices. The organization is well-respected, with companies often wary of its rigorous standards.
Opting for bamboo cups over plastic seems like a step towards sustainability and environmental consciousness. Bamboo is a renewable resource and is believed to be processed into cups without harmful chemicals. However, a 2019 examination by Stiftung Warentest revealed a significant discrepancy between marketing claims and reality.
Assessing Quality and Safety
The coffee cups in question were not purely made of bamboo. Instead, a melamine-based plastic was incorporated to enhance their structure. While melamine is safe at temperatures below 70 degrees, it can leach into beverages at higher temperatures, posing potential risks to the bladder and kidneys. Stiftung Warentest successfully demonstrated this concerning finding in the majority of the tested cups.
For the past six decades, Stiftung Warentest has been dedicated to evaluating products and services for quality and safety. Over this period, the institute has conducted around 9,200 tests. Each year, 30,000 products and services are rigorously assessed using scientific methods at independent testing facilities.

A Counterweight to Commercial Messaging
What began as a modest initiative in 1964 has evolved into one of the most prominent and influential consumer organizations in Germany. Founded at the request of then-Chancellor Konrad Adenauer, the institute was intended to serve as a counterbalance to the burgeoning advertising efforts of businesses.
The response from companies was largely dismissive; the Federation of German Industries argued that the public was already “sufficiently informed by advertising.”
The first test reports appeared in 1966 in the magazine ‘DER test,’ a publication that remains popular today under the ‘test’ title, reaching millions of readers. Consumers can now access these reports online or through an app, and the institute has successfully engaged younger audiences via social media platforms, including Instagram, where over 220,000 users follow its account.
Stiftung Warentest has evaluated 16 widely-used children’s game apps, with the majority failing to meet safety standards.
Independence as a Core Value
The foundation’s success is largely attributed to the impartiality of its assessments. Stiftung Warentest does not depend on advertising revenue or donations, primarily funding itself through the sale of test reports and publications.
Additionally, it has historically received annual grants from the federal government. As of this year, Stiftung Warentest has achieved complete independence from political influences, no longer relying on state support.
This change is significant, particularly as the organization has occasionally faced political backlash regarding its evaluations. The testers consistently set their own benchmarks, sometimes exceeding legal limits in their assessments.
In 2012, the foundation scrutinized Advent calendars for mineral oil contamination, identifying mineral oil in 24 products and advising against their purchase. However, the Federal Institute for Risk Assessment criticized the findings as exaggerated, leading to the introduction of guideline values for mineral oil contamination.
Stiftung Warentest also evaluated 31 toothpaste brands, issuing a particularly unfavorable review.
High Trust Among Consumers
Despite facing criticism from political entities and numerous legal challenges from companies regarding its findings, Stiftung Warentest continues to enjoy a strong reputation among the public. A 2023 survey by infratest dimap revealed that 74 percent of participants place significant trust in the organization, ranking it higher than institutions like the Federal Constitutional Court.
As a result, Stiftung Warentest has become a trusted name. A negative test result, especially a ‘poor’ rating, can significantly impact a product line’s success. Journalists frequently reference Stiftung Warentest reports in their articles, amplifying the reach of their evaluations.
Recently, Stiftung Warentest investigated suppliers of refurbished electronic devices.
Embracing Sustainability
In recent years, the importance of sustainability and ethical responsibility has surged. Consumers are increasingly mindful of product origins and their environmental impact. Recognizing this trend, Stiftung Warentest has started conducting tests focused on sustainability and eco-friendliness, including assessments of so-called sustainable fashion brands and natural cosmetics.
Even after 60 years since its inception, Stiftung Warentest remains committed to providing consumers with solid foundations for their purchasing decisions. ‘We exist to improve people’s lives,’ states board member Julia Bönisch. ‘It would be an overwhelming task if everyone had to research: What is the best refrigerator, the best travel cancellation insurance for me?’
