At Rwamatamu, quality starts with careful selection. Cherries are hand-sorted at the washing station to remove underripes and defects, then pulped in small batches, with the equipment washed between each grade to keep lots clean and distinct. After a controlled fermentation of 8 to 12 hours, the coffee is fully washed and dried slowly on raised beds for up to 25 days.

Every stage is designed to preserve clarity and showcase the impact of altitude and terroir. The result is a cup with structure and depth – bright, clean and balanced – shaped by methodical processing and the steady, cool climate of Rwanda’s Western Province.

This Red Bourbon lot is grown between 1600–2000 metres on the volcanic soils around Lake Kivu, where Rwamatamu’s mix of estate-grown and smallholder cherries are brought together to produce coffees with precision and purpose.

Year Started 2015
Location Western-Nyamasheke, Rwanda See on a map

Rwamatamu Coffee Ltd. is a family-owned business operated by Mukantwaza Laetitia and Rutaganda Gaston, who bring over 13 years of experience in the coffee sector. Founded in 2015, Rwamatamu Coffee Ltd. aims to achieve financial success while combating poverty in rural communities through sustainable coffee harvesting.

Rwamatamu boasts a 20-hectare coffee plantation, producing its own cherries and sourcing additional cherries from affiliated cooperatives, local producers, and smallholder farmers. Each batch is meticulously collected, processed, sun-dried, sorted, bagged, and ultimately exported as a premium product.

Nestled in the picturesque rolling hills of the Nyamasheke District in Rwanda's Western Province, our farm and washing station overlook the stunning Lake Kivu. This region offers a tropical highland climate with temperatures ranging from 14°C to 24°C and regular rainfall, ideal for growing Arabica coffee. The fertile volcanic soil at altitudes of 1600 to 2000 meters produces dense, hard beans with superior flavour.

Our coffee is fully washed with spring water, sun-dried, and handpicked to ensure the highest standards. We are currently in the process of obtaining organic and fair-trade certifications, reinforcing our commitment to quality and sustainability.

At Rwamatamu, we prioritise having a positive social and economic impact on our farming communities, especially focusing on empowering women. We collaborate closely with local cooperatives, and 80% of our workforce comprises women. Our mission is to foster healthy relationships with the community by committing to regular bean purchases, investing in employee growth, and maintaining high-quality standards each year.

    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.

    Highly recommend the Green Coffee Collective for all your raw green unroasted coffee beans. I’ve been buying from this company for a few months now, buying generally in 1Kg batches.The choice is amazing. I’ve had first class service, with great communication and speedy dispatch of all orders.

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 within the UK or EU, there are no extra customs charges or hidden fees. We warehouse UK orders in the UK and EU orders in the EU, so everything stays within the region. The price you see is the price 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.
