30ML Coffee Roasters

More About 30ML Coffee Roasters

30ML Coffee Roasters is a Dutch company operating within the specialty coffee sector. The name refers to the volume of a standard espresso shot. The business model consists of coffee bars operating under the name 30ML Coffee & Food and their own roastery. Public information places the roastery in Nijkerk, with the webshop address listed as Melkrijder 15D.

History and Founding

The origin story is described slightly differently across public sources. Misset Horeca mentions that the first 30ML location opened in 2009 on the Mariastraat in Utrecht. An interview cites 2011 as the moment Frans and Wendy left their jobs to start a small espresso bar in Utrecht. Mister Barish describes the roastery as being founded in 2013 by Wendy and Frans Kooijman.

Frans Kooijman and Wendy Kooijman are publicly named as the founders and owners of the 30ML brand. Their motivation stemmed from travels through the United States and Asia, where Frans Kooijman gathered inspiration from various coffee shops. The goal was to create an accessible espresso bar with a cozy, living-room atmosphere. For a later location, more than €20,000 was raised via crowdfunding in the first week alone.

Roasting and Methodology

According to their own description, 30ML began roasting their own beans to gain more control over the journey from bean to cup. The webshop describes the roastery as a blend of craftsmanship and science, creating specific roast profiles for single-origin coffees and blends. According to this information, the coffee is roasted weekly.

For their cafes, they source specialty coffees with a cupping score of at least 80 out of 100. It is also publicly documented that 30ML uses a Loring coffee roaster; a post from December 29, 2020, announced the arrival of a Loring roaster. The specific model, batch capacity, roast profile software, green coffee quality control protocols, and annual roast volume are not publicly documented.

Coffee Selection

The visible selection in the official coffee category includes Brazil Santos, Colombia Palermo, Colombia Palermo Filter, Ethiopie Guji Shakiso, Ethiopie Guji Shakiso Filter, Ethiopië Sidamo Decaf, and a Proefpakket Specialty Coffee. Location information also mentions Decaf Brazil Fruitas Proibidas.

Brazil Santos is described as a single-origin coffee from Minas Gerais in Brazil, consisting of 100% Arabica and processed using the natural method. Colombia Palermo is available in both espresso and filter variants and originates from Oporapa, Huila, Colombia. Ethiopie Guji Shakiso is likewise documented in espresso and filter variants, described as Heirloom coffee from the Guji zone near Shakiso.

According to product information, the Proefpakket Specialty Coffee contains three specialty coffees, with the contents changing regularly. For decaf products, CO2 processes are documented. Decaf Brazil Fruitas Proibidas is described as being decaffeinated using liquid CO2, while Ethiopië Sidamo Decaf is described as undergoing a CO2 process under controlled temperature and pressure.

Origin and Supply Chain

The franchise brochure states that 30ML often purchases green specialty beans directly from the farmer or cooperative in the country of origin, after which the beans are roasted in the Netherlands. For Brazil Santos, Exportadora Atlantica in Belo Horizonte, Minas Gerais is mentioned, a party that works with coffee farmers and cooperatives according to product information.

Colombia Palermo is linked to Juan Fernando Saldarriaga, who exports under Tierra de Cafe and collaborates with plantations in his region. Ethiopie Guji Shakiso is linked to the Shakiso Washing Station, led by Abder Malik Keder. The current visible origins in the webshop are Brazil, Colombia, and Ethiopia. An older industry blog also mentioned El Salvador and Malawi as historical origins.

Locations, menu, and retail

30ML describes itself as a franchise chain with 21 locations and its own coffee roastery. The official locations page lists sites in, among others, Almere, Amersfoort, Amsterdam, Deventer, Groningen, Hilversum, Hoorn, Leiden, Rotterdam, Tilburg, Utrecht, and Zeist. Announced upcoming locations are also listed. A separate tasting room at the roastery in Nijkerk is not publicly documented.

The coffee bars offer a drink menu featuring espresso, americano, filter, pour over, cortado, cappuccino, latte, and flat white. The food menu follows an all-day breakfast concept, including croissants, yogurt with granola, açaí bowls, avocado toast, grilled cheese, pancakes, sandwiches, and poached eggs. The webshop sells products categorized into coffee, tea, accessories, disposables, and tableware.

Sustainability, Recognition, and Community

Public environmental certificates and waste policies for 30ML Coffee Roasters are not documented. However, 30ML Nachtegaalstraat states that the location holds the LekkerVega Bronze certification, meaning at least 30% of the menu items are vegetarian or plant-based. The same location lists plant-based milk options such as oat, soy, and coconut at no extra cost. A social media post mentions that the Loring roaster is environmentally friendly, though no measured emission data is provided.

Public information links 30ML Nachtegaalstraat to the Horecaprijzen.nl elections in 2020, 2021, 2022, and 2023. In 2020, the location received 388 votes, an average rating of 9.64, and a national third place within the coffee shop category. In 2021, another Utrecht title was reported, with an average rating of 9.76.

Several examples of community activities have been documented. A 2015 article mentioned weekly workshops on tasting, brewing, pouring, and latte art. No current fixed workshop schedule was found publicly. For staff, the vacancies page mentions in-house training and additional training evenings. Furthermore, on September 19, 2020, the Nachtegaalstraat location opened a mini-library with Dutch and English books for adults and children.
