Klets Coffee Roasters

More About Klets Coffee Roasters

Klets Coffee Roasters is the in-house roastery of Barista op Wielen, a mobile coffee concept from Zeeland. Dylan van Overmeire is publicly recognized as the owner and founder of Barista op Wielen. After completing his barista training in 2022, he launched the mobile coffee concept.

The roastery emerged from a desire to have greater control over the roasting and preparation of coffee. A specific founding date for Klets Coffee Roasters is not publicly recorded. While the website features a copyright notice from 2024, it does not list that year as the start date. In a business announcement, both Klets and Barista op Wielen are linked to Terneuzen.

Roasting Method and Available Information

According to the roaster's own product information, Klets roasts coffee weekly in small batches. As a result, individual coffees may temporarily sell out between production runs. The assortment does not follow a fixed roast profile. Zomerstorm is described as a dark-roast blend, while Abaya is offered for both filter coffee and espresso.

Little is publicly known about the technical setup of the roastery. The brand, model, capacity, and installation year of the roasting machine are not published. There is also a lack of data regarding roast software, color measurements, fixed cupping protocols, and public roast curves. Consequently, the quality control used cannot be assessed based on public information.

Assortment and Origin

In July 2026, the public catalog consisted of five coffees and one sample pack. The range includes three coffees with a single named country of origin and two blends.

/01 São Paulo: coffee from Brazil.
/02 Abaya: coffee from Ethiopia.
/03 Tarazzu: coffee from Costa Rica.
/04 De Babbelaar: arabicablend uit Peru, Brazilië en Guatemala.
/05 Zomerstorm: dark-roastblend uit Peru, Colombia en Brazilië.
/06 Proefpakket: vier zakken van 500 gram, samen twee kilogram.

Origin information varies by product. Abaya refers to the Ethiopian district of Abaya but does not name a specific farm, washing station, or cooperative. Tarazzu appears to refer to the Costa Rican region of Tarrazú. According to the product information, this coffee is grown at altitudes between 1,200 and 1,800 meters and is washed-processed.

São Paulo is described only at the state level. Names of producers, estates, cooperatives, varietals, harvest years, and importers are missing. Barista op Wielen does express a preference for direct trade and fair compensation for producers. However, no specific trade contracts or farm relationships are publicly documented for individual Klets coffees.

Sustainability and business delivery

For business clients, Klets supplies coffee in reusable buckets. Barista op Wielen also highlights the avoidance of plastic, opting instead for biodegradable paper cups and recyclable materials. This approach applies to the mobile service and does not constitute a separate certification for the roastery.

The product pages do not display certificate numbers for organic or fair trade. Furthermore, no EU Organic, Fairtrade, Rainforest Alliance, or B Corp certification for Klets has been documented. Figures regarding emissions, green energy, packaging materials, waste streams, and reduction targets are not publicly available.

The coffee is sold via their own online shop, typically in 500-gram and 1,000-gram packages. In addition, Klets supplies the hospitality industry, retail shops, and offices. The business page mentions advice on coffee equipment and flexible delivery. A current list of external sales points has not been published.

Mobile hospitality and collaborations

A permanent café, a public roastery shop, or a tasting room for Klets has not been documented. Barista op Wielen serves coffee from a converted Piaggio Ape and a compact event bar. The closed mobile unit measures 2.70 by 1.35 by 1.95 meters. The smaller bar measures 1.46 by 0.64 by 1.80 meters.

The published menu includes, among others, espresso, ristretto, lungo, americano, cortado, cappuccino, flat white, and latte. The service targets trade fairs, congresses, corporate parties, festivals, and private gatherings in the Netherlands and Belgium.

In 2026, Klets collaborated on the espresso stout Kletsnat, alongside Dickies Brewing, Barista op Wielen, and Brouwerij D’n Emma. The beer featured espresso and ground beans from De Babbelaar. The reported alcohol content was 9.7 percent. Kletsnat was linked to the first Steens Bier Proef Festival in Sint Jansteen.

Team, pricing, and public profile

Dylan van Overmeire is the only publicly named owner and lead operator. No separate head roaster, buyer, or quality manager is mentioned. Staff numbers and the division of roles between the two companies are also not publicly available.

No coffee medals, published cupping scores, or roast prices have been found for Klets Coffee Roasters. Barista op Wielen does report results in a Zeeland food truck category for 2023 and 2024, including a third-place finish at the national level. These results relate to the mobile hospitality business, not the quality of the roasting.
