For us, sustainability is more than just a concept – it's part of our identity.

Since October 2024, we have been proud to be certified according to the ZNU standard "Sustainable Management". This holistic and certifiable sustainability standard requires a comprehensive management system that equally considers the three dimensions of environment, economy, and society.

"Bearing the ZNU certificate fills us with pride and, at the same time, motivates us to continuously develop," emphasizes Julian Tröger, Managing Director of Collectors Wine World.

"Sustainable action, especially in the wine sector, opens up enormous potential along the entire value chain – from production to delivery. Together with our partners and wine producers, we aim to strategically leverage these opportunities."

By implementing the ZNU standard, we were able to establish an effective sustainability management system. In doing so, we identified key areas of action, defined concrete goals based on these, and implemented targeted measures. This creates the basis for making our progress measurable and continuously improving – step by step towards more responsible business practices.

The annual review by independent auditors, in our case TÜV Rheinland, ensures that we permanently meet the requirements of the standard, consistently pursue our goals, and continue to develop year after year.

As a member of Wine in Moderation, we also commit to a conscious and responsible approach to wine. This international program promotes moderate wine consumption and supports a culture of mindfulness – values that we actively embody and wish to pass on as a company.

Less Packaging Material

We have set ourselves the goal of reducing single-bottle shipments by 15% by the end of 2025 compared to 2023 – thereby significantly saving packaging waste and shipping materials.

Our wines usually arrive in cases of 6. If we can ship these unopened, we avoid elaborate individual packaging and thus significantly reduce material consumption. However, as soon as a case is opened, all bottles must be individually packaged and shipped – which requires significantly more resources.

Through targeted measures, such as special offers to promote 6-bottle case sales, we were able to far exceed our original goal:
From 2023 to the end of 2025, we reduced the proportion of single-bottle shipments by over 70%.

Sustainable Wines

Sustainability plays a central role in our assortment.

Significant progress is already visible: The organic share of our new procurements in 2025 is 16.1%, and customers in the online shop have their own filter option for organic wines. Around 5.6% of our total assortment – which corresponds to about 170 of currently around 3,000 items – comes from organic or biodynamic cultivation. We are also increasingly focusing on climate protection in logistics: Through proactive procurement, preferably in cooler seasons, we were able to reduce the number of necessary refrigerated transports in summer to just three. In addition, we are continuously expanding our regional offerings. This year, four new German producers with over 20 additional wines have been added. This brings us closer to our goal of including a total of 25 German producers with more than 120 products in our assortment by early 2027. These developments show that we have already come a good deal closer to our goal of making sustainable wines clearly recognizable and consistently increasing their share.

Customer Focus

We set ourselves the goal of establishing a rating function for our customers in the online shop by the end of 2024. Based on this feedback, we wanted to improve the results of the first survey by 20% by the end of 2026.
We successfully introduced this rating option at the end of 2024 and evaluated the first results a year later, at the end of 2025. The average customer satisfaction is an excellent 4.59 out of 5 points. Since this level is already very high, we aim to maintain this value at least until the end of 2026.
We take our customers' feedback very seriously – and therefore launched our new website at the end of 2025, which puts the customer experience at its core. Our goal is for every visitor to find exactly the wines that suit them and their preferences.
In addition to optimized search and filter functions, we now offer even more detailed information about our wines and their regions. At the same time, we have further expanded our product portfolio to offer every customer their very own favorite wine.

Social Commitment

We are locally engaged and support sustainable projects in our communities. Our employees have the opportunity to actively participate in a social project of their choice for two days per year with full pay.
Unfortunately, we were unable to achieve our goal for 2024 – a total of 120 hours of social engagement – due to internal restructuring. For 2025, we therefore set an ambitious goal of 240 hours – and even exceeded it:
In 2025, our employees dedicated a total of over 256 hours to social and ecological projects.

We aim to support small to medium-sized wineries that operate sustainably. They are not only mostly family-run and more hands-on, but they also care for the environment, as it is their primary resource. Few industries are as intensely affected by climate change as viticulture, which is why we want to promote these wineries to secure a good ecological and economic future. Furthermore, our tastings show that smaller wineries produce significantly better wines. The best wineries in the world have pioneered ecological management systems; this also suggests that the path to the top only works with sustainability.
