Zera Koffie

More About Zera Koffie

Zera Koffie is a Dutch coffee roastery registered under the business name Zera Koffie. Available public records list KvK number 24453752 and a contact or registration location in Mijnsheerenland. Official information clarifies that the contact address is not a visit address. The specific founders and year of establishment are not publicly documented. However, WebwinkelKeur notes that Zera Koffie has been a member of this certification since 2020.

The roastery describes its origins as stemming from an interest in coffee and the production chain. It is also noted that the coffee roaster is a psychiatrist by training. The location is described as a roastery in a shed in a garden, in a village near Rotterdam. No additional information is documented regarding team size, other employees, or publicly listed roles.

Roasting process and methodology

Zera Koffie states that it roasts and sells organically and sustainably grown coffee. A central part of its approach is the order model: according to its own information, coffee is roasted after an order is placed. This indicates production on demand, but details regarding roast profiles, software, batch size, or roasting machines used are not publicly available.

The webshop offers various grind and packaging formats. Product pages list options for whole beans, espresso grind, and filter grind. Sizes of 250 grams, 500 grams, and 1 kilogram are also documented. The page on coffee beans distinguishes between single-estate and single-origin coffee. However, it remains unclear what technical choices the roastery makes per origin or per brewing method.

Assortment and origins

The current category listing all products mentions six coffee products. The offering consists of country- or origin-labeled coffees. Listed products are Honduras Arabica Organic Coffee Washed, Sumatra Mandheling Arabica Organic Coffee Raja Gayo Semi Washed, Peru Premium Arabica Organic Coffee Washed, Brazil Arabica Organic Coffee Natural, Colombia Excelso Organic Coffee Washed, and Guatemala Arabica Organic Coffee.

The documented countries of origin are Honduras, Indonesia/Sumatra, Peru, Brazil, Colombia, and Guatemala. For Honduras, La Paz is mentioned, where 62 coffee farmers collaborated in the transition from conventional to organic cultivation. The coffee from Peru is described as coming from 25 small coffee farms in Cajamarca, at an altitude of 1,600 to 1,865 meters. GPS coordinates are also listed for this origin.

For Sumatra, the Batak region in Aceh is mentioned, with cultivation on hills in the area of the Leuser volcano. For the remaining origins, organic cultivation is primarily noted as a characteristic. Names of farms, cooperatives, exporters, importers, or fixed direct-trade partners are not publicly documented. Additionally, no blends are listed in the current product overview.

Sustainability and Social Information

Sustainability is a recurring theme in the published information about Zera Koffie. The roastery states that it sells organically and sustainably grown coffee. It also highlights farmer income as an important part of its purchasing policy. A specific amount is also documented: €1 is donated per kilogram of coffee sold to social projects in countries where coffee is sourced.

Product pages describe organic cultivation for coffees from Honduras, Peru, Brazil, Sumatra, Colombia, and Guatemala. A certification number or the name of a controlling authority is not publicly documented on the reviewed pages. As a result, based on the available information, it remains unclear how the organic claims are administratively verified. Information regarding waste policy, packaging materials, emissions, or energy use is also not publicly available.

Zera Koffie is also listed by The Ocean and Us as an organization or company supporting a call for a moratorium on deep-sea mining. Burgh-Haamstede, The Netherlands, is listed with this mention. Further information about the nature of this involvement is not documented in the available material.

Sales, Education, and Public Access

The primary sales channel is the Zera Koffie webshop, which is described as being open 24 hours a day. For weekend orders, delivery is scheduled for Tuesday. In addition to coffee, the webshop offers gift vouchers as a separate product feature. There is no publicly documented information regarding wholesale accounts, supermarkets, cafés, or other retail partners.

No public café, tasting room, or fixed visitor program is documented. Furthermore, the contact address information indicates that this is not a visitable location. The roastery does, however, publish educational content on brewing methods. Documented topics include the moka pot, Chemex, AeroPress, and espresso. Public cuppings, tastings, paid workshops, or recent events are not recorded.

Registrations, Reviews, and Visibility

WebwinkelKeur lists Zera Koffie as a member since 2020 and notes a legal check from 09/2022. It also displays five customer reviews with a score of 10. Google Safe Browsing and SSL status are listed by WebwinkelKeur as received in 05/2026. Awards from coffee competitions or industry organizations are not publicly documented. No coverage was found in specialized international coffee media such as Sprudge, Perfect Daily Grind, or Daily Coffee News.

Consequently, the public image of Zera Koffie is primarily based on webshop information, product descriptions, and a few external registrations. The available data depicts a small-scale roastery with a limited range of organically described origin coffees, online sales, and a fixed donation amount per kilogram sold. At the same time, several details that often provide extra context for coffee roasters are missing, such as team names, roasting equipment, certification data, and fixed chain partners.
