Anaerobic fermentation

Anaerob Fermentatioun

Anaerob Fermentatioun ass Deel vun enger klenger wëssenschaftlecher Revolutioun am Kaffi. Dëse Prozess ouni Sauerstoff erlaabt eng kontrolléiert, verlängert Fermentatioun, déi d’Komplexitéit erhéicht, ouni de Risiko vun Iwwerfermentatioun. Egal ob d’Boun an der Kiischte fermentéiert (anaerob natural) oder no der Entpulpung (anaerob washed), d’Resultat ass e Kaffi mat markanten, ënnerschiddlechen Aromen – dacks fruuchteg, wäinähnlech oder liicht funky.

Dein Guide zu Anaerob Fermentatioun

  • What is anaerobic fermentation in coffee processing?

    Anaerobic fermentation is an experimental coffee processing method where coffee cherries or beans ferment in a controlled, oxygen-free environment. Producers place them in sealed tanks with one-way valves that prevent oxygen from entering while allowing carbon dioxide, which builds up during fermentation, to escape. This process enables extended fermentation without the risk of undesirable flavours from over-fermentation. The lack of oxygen slows fermentation, allowing the beans to absorb more sugars and compounds from the cherry. This often results in distinctive flavour profiles, with notes that can be intensely fruity, wine-like, or even slightly funky, depending on the process used.

  • What is the difference between anaerobic and aerobic fermentation?

    The main difference is the presence of oxygen. In aerobic fermentation, oxygen is available, which speeds up the breakdown of sugars in the coffee. Anaerobic fermentation happens in an oxygen-free environment, slowing the process and allowing microorganisms to work more gradually. This controlled, slower fermentation can enhance complexity in the coffee’s flavour profile, often creating deeper and more complex flavours compared to traditional fermentation.

  • What is the difference between anaerobic natural fermentation and anaerobic washed fermentation?

    Anaerobic natural fermentation means the coffee bean remains inside the cherry throughout the fermentation process. Since the bean is still surrounded by fruit, it absorbs more sugars and organic compounds, resulting in a coffee with bold, fruit-forward flavours and heightened sweetness. In contrast, anaerobic washed fermentation involves removing the bean from the cherry before fermentation begins. Without the surrounding fruit, the fermentation process produces a cleaner, more structured flavour profile while still benefiting from the unique characteristics of an oxygen-free environment.

Was ist das Green Coffee Collective?

Wir sind eine Gemeinschaft aus Kaffeebauern und Beschaffungsexperten, die zusammen daran arbeiten, den Zugang zu Rohkaffee so einfach wie möglich zu machen – egal ob du zu Hause als Hobby röstest oder als Profi hunderte Tonnen im Jahr verarbeitest. Unsere Plattform macht den Einkauf von Rohkaffee so unkompliziert wie jeden anderen Onlinekauf. Kein Aufwand, nur großartiger Kaffee – direkt für dich verfügbar.

How do I find the coffee right coffee for me?

It’s super easy! Just head to our coffee pages and use the search filters to narrow down what you’re after. Whether it’s origin, process, or variety, the filters make it simple to find exactly what you want. You can also check out the main coffee categories through the top menu on our site. Give it a go—it’s straightforward, and if you need help, we’re always here!

Are your coffees ethically and sustainably sourced?

Absolutely! We source all our coffees either directly from producers or through trusted sourcing partners who are just as committed to ethical practices as we are. We take the time to ensure the people behind the coffee are treated fairly. If you want to learn more, you can dive into our values.

What sizes or quantities can I order?

We offer coffee starting from as little as 0.5kg (1 lb) all the way up to full sacks. If you’re looking for larger quantities than what’s listed on our site, just get in touch! We’d be happy to help you organise and place a custom order. We're here to make sure you get exactly what you need.

How fast will I get my order?

If you choose express shipping, your order could arrive in as little as 24 hours (depending on your location). For most orders, if you place it before 12pm, we’ll ship it out the same day! Otherwise, it’ll be dispatched the next day. We aim to get your coffee to you as quickly as possible.

Unterstützt ihr beim Aufbau von Direct-Trade-Beziehungen mit Produzenten?

Ja, wir stellen sehr gerne den Kontakt her! Wenn du direkt mit einem unserer Produzenten zusammenarbeiten möchtest, schick uns einfach eine E-Mail an (hello@greencoffeecollective.com) und wir unterstützen dich bei der Verbindung. Bei größeren Mengen helfen wir auch bei Logistik und allen weiteren Details, die beim direkten Einkauf entstehen können.

Do you offer samples or trial batches before committing to larger orders?

Yes, we offer samples for most of our coffees. If you need a larger sample than what’s typically available, we recommend trying one of the smaller quantity options listed on our site. That way, you can test the coffee before committing to a larger order.

How do you handle logistics and shipping for larger orders?

We’ve got you covered! For larger orders, we offer full logistical support, including freight, warehousing, and inventory management. We’ll make sure the process is as smooth and hassle-free as possible, so you can focus on roasting great coffee. If you’re shipping internationally, we can also assist in ensuring smooth delivery.

What is your minimum order quantity (MOQ) for large-scale or long-term contracts?

For larger-scale or long-term contracts, you can start with as little as a single bag. We’re also working on tools to help you access harvests and reserve coffees before they even leave the country. While it’s not fully ready yet, we’re always here to help roasters of any size connect with the producers they want to work with.
