This Mundo Novo lot from Mio shows how clean, controlled processing can bring out the best in classic Brazilian varieties. Ripe cherries were fermented in closed tanks for 72 hours using Saccharomyces cerevisiae as a starter yeast. Glucose and fructose were added to guide the fermentation, helping unlock the coffee’s full flavour potential.

The process took place in Mio’s purpose-built wet mill, with close control over temperature and oxygen levels throughout. After fermentation, cherries were dried using a mix of raised beds, concrete patios and ambient-air rotating dryers. Final sorting involved density separation, screening by size, and optical-electronic colour sorting to ensure top-grade results.

Name Mio
Location Monte Santo de Minas See on a map

Mio is a distinguished coffee farm located in Monte Santo de Minas, Brazil. As both a producer and exporter, Mio is dedicated to harvesting coffee with exceptional care, ensuring that every bean meets the highest standards of quality.

Farm Overview

Spanning 1,589 hectares, Mio's farm is a blend of innovation and tradition. One-third of the land houses coffee processing and milling facilities, pasture areas, and eucalyptus plantations, which support a thriving bee population. The remaining land is equally divided between coffee trees and a native forest reserve, reflecting Mio's commitment to environmental sustainability. The farm, enriched with ample spring water, prioritizes maintaining and improving water quality.

Unique Terroir

Situated between the Southern Minas Gerais and High Mogiana regions, Mio benefits from two distinct terrains. This unique location imparts a citric acidity and a full-bodied sweetness to the coffee, creating a well-balanced and flavorful cup.

Commitment to Sustainability

Mio dedicates equal land to coffee cultivation and forest preservation, maintaining the natural characteristics of the area. This balance ensures that the local ecosystem thrives alongside coffee production.

Traceability and Technology

Mio guarantees 100% traceability for every crop, every year. Using satellite imagery and advanced tracking technologies, each stage of the coffee's journey is meticulously recorded - from cherry harvesting to processing. This technological approach not only enhances farmworkers' quality of life but also ensures abundant harvests and the highest processing standards.

State-of-the-Art Processing Facilities

Mio's processing facilities are equipped with cutting-edge technology, including:

  • A wet-mill
  • Concrete patios and raised beds for drying
  • Ambient-air drying rotating machines
  • Wood silos and cross-beater hullers
  • Density separators

Further sorting by size and color is achieved using an oscillating screen and an optical-electronic system, ensuring only the finest beans make it to the final product.

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.
