Baobab Coffee Roasters

More About Baobab Coffee Roasters

Baobab Coffee Roasters is a young coffee roastery in Delft, Zuid-Holland. The company is publicly described as an independent micro-roastery situated in the Hortus Botanicus Delft. The business address is listed as Poortlandplein 6, 2628 BM Delft. Company information cites 2023 as the founding year and places Baobab within the food and beverage production sector.

Origins and Location

The roastery is linked to Coffee-star, the company owned by Jan Willem Keus. Keus and Mateusz Bartosik roast under the name Baobab Coffee Roasters in the Hortus Botanicus. Bartosik is mentioned as a co-founder, barista, and manager at Coffee-star. According to available information, Keus began roasting approximately three years prior to November 2025. He sought greater transparency within the coffee chain, from bean selection to the moment of serving.

The choice of the Hortus is linked to a connection with nature and coffee plants. Coffee plants also grow within the botanical garden, although not on a production scale. Consequently, the location holds primarily symbolic and practical significance within the roastery’s profile.

Roasting and Methodology

Baobab roasts fresh beans weekly in Delft. Roasting days take place on Mondays, when the Hortus is closed. According to documented information, an average roasting day yields approximately 100 kilos of coffee in two hours. The coffee is then distributed to Coffee-star locations and to TU Delft.

During roasting, temperature, airflow, and time are adjusted. These choices depend on the characteristics of the green coffee beans. Factors such as density, size, hardness, and moisture content play a role. Earlier company information mentioned a 1.8 kilo roaster. Later, a larger roaster was mentioned. The brand and model of that roaster are not publicly documented.

Coffee Offering

The publicly known assortment is described in limited detail. In November 2025, a batch featuring beans from Brazilië and Ethiopië was mentioned. According to available information, Baobab always creates a blend. Additionally, older company information refers to “Single Origins” from the Hortus, with Rainforest Alliance certification.

A current webshop catalog is not publicly documented. The website mentions a shop section marked “coming soon”. Names of blends, roast profiles, packaging sizes, subscriptions, and current product lists are not publicly recorded. Public pricing is excluded from consideration.

Sourcing and Origin

According to available information, Baobab uses organic coffee beans sourced by the team themselves. For the documented roast in November 2025, Brazilië and Ethiopië were named as the countries of origin. Keus links independent sourcing to variety in coffee types and insight into origin.

Many details regarding the supply chain are not public knowledge. There are no documented mentions of specific estates, cooperatives, importers, harvest lots, or producer payments. Additionally, an annual transparency report concerning sourcing and origin is not publicly available.

Sustainability and logistics

The available information mentions several practical measures regarding waste and transport. Roasted beans are delivered to Coffee-star locations in buckets, which are then returned and refilled. This limits packaging waste within their own distribution network.

Electric transport is mentioned for logistics. Furthermore, coffee ground streams are collected by Rotterzwam, which utilizes the grounds for mushroom cultivation. Coffee-star describes sustainability more broadly as part of its business operations, focusing on certification, packaging, and waste reduction.

Distribution and locations

Distribution primarily runs through Coffee-star and TU Delft. The roasted coffee goes to TU Delft and partly to other Coffee-star locations. Coffee-star mentions locations including Hortus Botanicus Delft, Library TU Delft, and Coffee&Bikes TU Delft.

A public network of independent retail partners outside of Coffee-star and TU Delft is not documented. Nor is there a standalone Baobab tasting room with its own menu, booking calendar, or cupping program publicly recorded. The Coffee-star location at Poortlandplein 5 in the Hortus is listed as a café and event venue.

Team and activities

Jan Willem Keus is mentioned as the owner of Coffee-star and as one of the roasters behind Baobab. Coffee-star started in 2006 and, as of November 2025, had approximately 70 employees and 10 branches. Mateusz Bartosik was born in 1995 and had ten years of experience in the coffee sector at that time.

Beyond Keus and Bartosik, no additional team members are publicly documented. Occasional activities are mentioned, such as roasting courses within Keus’s network. Roastery visits and samples for business clients are also mentioned in public communications. A fixed public events calendar under the name Baobab is not documented.

Public Profile

Baobab Coffee Roasters sits at the intersection of a micro-roastery, campus facility, and Coffee-star distribution. The available information primarily shows a small-scale, operational structure. At the same time, part of the company profile remains limited in visibility, particularly regarding the assortment, sourcing details, retail partners, and regular public activities.
