30ML Alexandrium

30ML Alexandrium, located in the Alexandrium shopping center in Rotterdam, is part of the broader 30ML coffee group, known for its focus on specialty coffee and an extensive selection of breakfast and lunch dishes. What started as a small espresso bar has since grown into a successful Dutch franchise with its own coffee roastery.

The 30ML coffee bar is built around the philosophy of pairing specialty coffee with high-quality breakfast and lunch options in a relaxed, social atmosphere. This concept, developed by the founders, is reflected in the vibe of the Alexandrium location, which is presented as a “second living room” for visitors. Quality, hospitality, and a focus on house-roasted beans are core values found across all 30ML locations.

The coffee served at 30ML Alexandrium comes from 30ML Coffee Roasters, the brand’s own roastery. Here, carefully selected specialty Arabica beans are roasted with a medium-light profile, ensuring a balanced flavor between acidity and complexity.

Popular brewing methods at 30ML include classic espresso’s and filter coffee, making both espresso-based drinks and more refined pour-overs available to guests. Alongside the coffee, the menu features seasonal and specialty drinks such as the lavender matcha latte and salted maple matcha latte, contributing to a diverse coffee culture.

The 30ML location in Alexandrium is not just a spot for coffee, but also a meeting place where people can enjoy brunch and lunch in a laid-back setting. This makes the café a social hub within the Alexandrium shopping area. The café’s Instagram account plays a key role in strengthening the bond with the local community by sharing seasonal offers and lifestyle-related content.

While there are no specific details available online regarding events such as workshops or cuppings organized at Alexandrium, the location remains popular due to its informal atmosphere and its role in the Rotterdam coffee culture.

The 30ML coffee group operates on the principle that all coffee beans are carefully selected from trusted growers and roasted in-house. This gives them full control over the quality and traceability of the coffee from bean to cup. Regarding sustainability, however, there is no detailed information available about specific initiatives or programs for the Alexandrium location, such as direct trade programs or waste reduction. Other 30ML locations offer plant-based milk and reusable cups, but such measures are not specifically documented for Alexandrium.

While other 30ML locations, such as 30ML Nachtegaalstraat in Utrecht, have won several awards—including the title of “Best Coffee Shop in Utrecht” in various years—there is no specific award or major recognition for the Alexandrium location. Nevertheless, 30ML cafés, including Alexandrium, receive overwhelmingly positive reviews. Visitors particularly praise the quality of the coffee, the atmosphere of the café, and the welcoming staff.
