Duma Kenya RA

Commerical Green Coffee Beans from Kenya

Commercial

Duma is sourced primarily through the Nairobi Coffee Exchange Auction, drawing on a wide network of smallholder producers farming the slopes of Mount Kenya and throughout the Aberdare mountain range, in Kenya's Central Province.

The auction system is excellent at spotting outstanding microlots, but for most smallholders, those standout lots represent only a small fraction of their total harvest - and while farmers may earn more selling that portion at auction, the small size of such lots means they still rely on selling the rest of their crop at fair prices. Duma exists to close that gap: a blend of ABC size grades that provides a consistent product in greater volume, while ensuring farmers get a good return across their entire harvest, not just their best lots.

It's fully washed, grown between 1,600–1,850 masl in rich volcanic sandy soils, and made up of Batian, Ruiru 11, SL28 and SL34 varietals. Following selective handpicking, cherry is delivered to central wet mills - known locally as "Coffee Factories" and generally run as cooperatives - where it's hand-sorted to remove damaged or underripe fruit, pulped, fermented for 12–16 hours, and washed in fresh, high-altitude stream water. The wet parchment is then dried on raised beds, turned frequently for even drying, with workers sorting through it by hand to remove any damaged beans. The coffee is graded ABC, scores 80+ SCA, and is Rainforest Alliance certified.

Name Smallholder farmers across Nyeri
Location Nyeri, Central Kenya See on a map

typically farming 250–350 trees on average, on the slopes of Mount Kenya and throughout the Aberdare mountain range. Coffee is grown in rich volcanic sandy soils at 1,600–1,850 masl, with flowering between March and April and harvest spread between November and January (Central Kenya's early crop runs May–July, with a late crop October–December).

Smallholder farmers here are organised into central wet mills known as "Coffee Factories," which generally function as cooperatives - part of a wider system of hundreds of Farmer Cooperative Societies (FCS) across Kenya, each operating at least one factory. More than 600,000 smallholders farming under 5 acres make up 99% of Kenya's coffee farming population, covering over 75% of the country's coffee land and producing nearly 70% of its total output. The remainder is grown and processed by small, medium and large estates, most of which run their own washing stations.

This blend is created by Sucafina Kenya, Sucafina's in-country sister company, which works with farmers across Kenya to help their coffee gain the recognition it deserves. Despite a relatively late start compared to other origins, Kenyan coffee has built a strong reputation for quality, meticulous preparation and distinctive flavour - a standard upheld by rigorous sorting at cherry intake and, at many factories, long-serving, experienced management.

    I've been roasting coffee at home for about a year, sourcing green beans from various suppliers. I recently came across Green Coffee Collective and was genuinely impressed. They have a fantastic selection of green coffee beans, and shipping was smooth and communication was excellent. My first order arrived fresh and well-packaged in a heavy-duty, hermetically sealed zip bag with nine-layer protection—easily the best green beans I've purchased so far.

How we package
our coffees

Barrier packaging designed for specialty coffee.

We use Ecotact bags because they offer high-barrier protection against oxygen, moisture, and external contaminants. This helps preserve the quality, aroma, and flavour potential of your green coffee during transport and storage. They're trusted by top producers and importers worldwide.

Heat-Sealed for Maximum Protection

Every bag is professionally heat sealed at our warehouse to lock in freshness. This creates a secure seal that prevents exposure to air or humidity - keeping your green coffee stable, even over long periods.

Convenient Resealable Zip Closures

Once opened, each bag has a resealable zip to help you store and protect the rest of your coffee between roasts. It’s a simple way to reduce waste and maintain freshness - especially helpful for home roasters or sampling.

Portion sizes for any roaster.

Whether you're roasting at home or running a production line, we've got a size to suit. Choose from 0.5kg, 1kg, or 5kg bags - all packed with the same level of care. Smaller volumes make it easy to try new coffees without the commitment.

Responsible packaging choices.

Our bags are made from Graded 7 multi-layer recyclable plastic. While they may not go in your home recycling bin, they are accepted by specialist facilities. More importantly, they reduce waste by dramatically extending the shelf life of your green coffee.

Frequent Questions

Is your coffee unroasted?

Yes – all the coffee we sell is raw, unroasted green coffee unless clearly marked as a roasted sample. It might sound obvious, but it's one of the most common questions we get! If you're buying from us, you're getting green coffee ready for roasting.

How long does delivery take, and can I track my order?

We usually pack and dispatch orders within 1–2 working days. Once it’s on the move, you’ll get a tracking link so you can follow it all the way to your door.

For UK and EU deliveries, most orders arrive within 2–5 working days. International shipping can take a little longer depending on customs, but we’ll keep you updated every step of the way.

If you need your coffee urgently, you can select an express shipping option at checkout.

How does your quality guarantee work?

We stand by every coffee we offer — if the quality doesn’t match the listing, we’ll refund or credit you. No fuss.

We work directly with specialty producers and sourcing partners who are deeply connected to their regions. Every coffee is selected based on quality, transparency, and value — and we always share the details up front, from processing to cupping scores.

If something feels off when your coffee arrives, just get in touch. We’ll put it right, every time.

Will I need to pay customs duties or taxes?

No. If you’re ordering from the UK or the Europe, there are no customs charges or hidden fees.

We ship UK orders from our UK warehouse and EU orders from our EU-based warehouse, so everything stays within the region.

For UK customers, the price you see on the product page is the final price.

For EU customers, VAT rates vary by country, so your final price (including the correct local VAT) is shown clearly at the final step of checkout before you pay.

What payment methods do you accept?

We accept all major credit and debit cards (Visa, Mastercard, Amex), plus PayPal. You can also use gift cards at checkout. If your gift card doesn’t cover the full amount, you can easily top it up with another payment method.

How does your pricing work?

We keep our pricing simple, transparent, and fair. What you see on the product page is the final price per bag - no hidden fees, no surprises at checkout.

Prices are based on the coffee's quality, variety, processing method, and how it's sourced. We offer multiple sizes (from 0.5kg to 5kg), with smaller sizes priced to include repacking and packaging costs. Shipping is free, and VAT is already included in the price you see.

Do you offer any roasting advice for green coffee?

Absolutely. We work with roasters of all levels – from complete beginners to seasoned pros – and we’re always happy to share what we know.

You’ll find starter tips and roast profiles on our blog, or you can drop us a message if you’ve got questions about a specific coffee. A medium roast is usually a great place to start - it gives you a balanced view of the coffee’s flavour, and you can adjust from there.

What is your return policy if I'm not satisfied with the coffee do you offer any guarantees?

We want you to be happy with every coffee you try. If something doesn’t feel right - whether it’s a quality issue or your order isn’t what you expected - just get in touch. We’ll always do our best to put it right, whether that means a replacement, refund, or store credit.

Is there any customer support available if I have questions after purchasing or if something goes wrong?

Definitely. We’re here to help before, during, and after your order. If you have any questions about your coffee, roasting, or if something’s gone wrong with your delivery, just reach out. We’re a small team, but we’re quick to reply and always happy to sort things out.

You can contact us by email (hello@greencoffeecollective.com) or through the form on our website whatever works best for you.

What do your flavour notes mean?

Flavour notes describe the natural characteristics found in the coffee - shaped by things like variety, processing, and how it’s cultivated.

You might notice hints of chocolate, red fruit, florals or citrus. These aren’t added flavours - they’re subtle notes that come through when a coffee is grown, processed, and roasted with care. We include detailed origin info and flavour profiles on every product page to help you choose the right coffee for your taste.

Can I sample the coffee before purchasing?

Yes - we offer samples for nearly all of our coffees. There’s a small fee to cover the cost of packaging, green coffee, and prep, but it’s a great way to try before committing to a larger order.

Samples may not be available on limited-release or rare coffees due to low stock. If you’re unsure, just get in touch - we’re happy to help you find the right fit.

Unfortunately we can't offer samples in the EU yet.

How does the Cupping Score translate into taste or quality?

The cupping score is a quality grading system used by coffee professionals. It’s based on how a coffee tastes in a controlled tasting — looking at things like sweetness, balance, acidity, and complexity.

80–84 = Clean and consistent with good flavour — great everyday coffees.

85–87 = More complexity, distinct flavours, and refined sweetness.

88+ = Exceptional – rare, expressive coffees with standout characteristics.

Scores help you understand what to expect in the cup, but taste is personal. We include flavour notes and process details on every product page to help you find what suits your style best.

What’s the best way to brew this coffee once it’s roasted?

That depends on the coffee and how you like to drink it — but most of our coffees will shine as a filter brew (like V60, Chemex, or batch brew) or as a single origin espresso.

We’ve grouped our coffees into helpful collections like Espresso, Fruity Filter, and Cold Brew to guide you toward the right fit. Once roasted, feel free to experiment - you’ll quickly discover what brings out the best in each bean.
