Tasting Notes: Mango, Passionfruit, Cacao nibs
Cupping Score: 85.0
?
Our coffees are scored using the Specialty Coffee Association (SCA) protocol by Q Grader–certified cuppers. A score of 80+ qualifies as specialty grade — clean, well-processed, and high quality. 80–84 coffees are more common and often used in blends. 85–87 are brighter, more complex, and better suited for high-quality filter brews. 88–90 are exceptional, and 90+ coffees are ultra-rare, often Cup of Excellence (COE) winners — the best in the world.
Suitable To Go With Milk?: No
?
Some of our light roasted filter coffees are bursting with bright, fruity acidity—think citrus, berries, or tropical notes. While these flavours shine on their own, they don’t always play well with milk. The acidity can clash with milk’s natural sweetness and creaminess, sometimes creating sour or chalky flavours.
Roast Profile Filter
?
Filter roasts are lighter with a shorter development time, designed to highlight clarity, acidity, and fruit-driven complexity — perfect for black coffee and filter methods. These roasts can also be used for espresso, especially if you enjoy brighter, more vibrant shots. Try longer brew ratios or turbo shots to tame acidity and bring out sweetness. Espresso roasts, on the other hand, are developed further to encourage deeper caramelization and Maillard reactions, producing richer, chocolatey, and nutty flavours that shine in milk and offer a fuller-bodied espresso. We don’t usually roast omni (one roast for all brew methods) — in our experience, it tends to be a compromise that’s average at both. But occasionally, for larger lots or versatile blends, we may do an omni roast to suit both black and milk drinkers.
Micron Adjustment: -40
?
This shows how the recommended grind size for this coffee differs from our baseline Coastal Blend setting. A negative number means a finer grind is recommended; a positive number means coarser. It helps dial in your grinder without starting from scratch.
Internal Agtron: 102 (Very Very Light - Scandinavian / Nordic Roast)
?
This is a more accurate reflection of the actual roast level than external Agtron. Measured after grinding, internal Agtron reveals how far into the bean the roast has penetrated. Our filter roasts often score over 100, preserving acidity, florals, and the unique vibrant characteristics of each origin and process.
External Agtron: 78 (Light - Cinnamon Roast)
?
This refers to the surface colour of the whole roasted bean, but it's not always a reliable indicator of roast level - Some of our most vibrant and lightly roasted coffees like our Ecuadorian Sidra, may appear medium-dark (Agtron 50–60) due to their surface color, yet are in fact light roasts with minimal development time. Surface colour can be affected by the original green colour, bean type, density and moisture - so don't judge a bean by its exterior.
Agtron Spread: 24
?
The Agtron spread is the difference between the colour of whole beans and ground coffee, showing how deeply the coffee is developed. A spread of 0–10 usually are very dark, oily roasts typical of Italian-style which we dont offer at our Roastery. Spreads between 11–20 and 21–30 represent the roast levels you’ll find in our espresso coffees, balancing sweetness, acidity, and body. Spreads above 30 make up most of our filter coffee range, featuring very light, bright roasts that highlight fruity, floral, and complex flavours. Within this, spreads from 31–40 offer clarity and vibrancy, while spreads of 40–50 showcase ultra-light roasts with delicate acidity and nuanced character.
Roasted On Machine: Roest L100 Plus
?
The ROEST L100 is a game-changer in the world of sample roasting, designed with precision, automation, and data transparency at its core. Unlike traditional sample roasters that rely heavily on manual control and visual cues, the L100 gives you full control over temperature, airflow, and drum speed—while also logging every variable in real time. With a touch screen interface, built-in Wi-Fi, and cloud connectivity, it allows for consistent, repeatable roasts and effortless profiling. Whether you're cupping for quality control or exploring new green lots, it eliminates guesswork and brings lab-level control to your coffee bench. What sets the L100 apart from other roasters its size isn’t just the tech—it’s the consistency, repeatability, and scalability. Other small sample roasters often struggle to replicate curves or to match the flavor development seen in production roasting. The L100 bridges that gap with unmatched thermal stability and accurate replication, meaning your sample roasts can translate more faithfully to your larger batches. Plus, features like automatic preheating, auto-drop, exhaust sensors, and compatibility with Cropster or Artisan make it not just a roaster—but a full-on data-driven coffee lab in a shoebox-sized footprint.
Coffee Storage Climate Controlled
?
This green coffee is stored at 23°C in a climate-controlled room, which is a step up from standard warehouse storage, as the ambient temperature does not fluctuate as much
Varietal: Castillo
?
Castillo is a Colombian-developed hybrid, designed for rust resistance and high yield. It includes genetics from Caturra and Timor Hybrid. While early versions were criticized for mediocre cup quality, modern strains can be quite good, with fruit-forward and balanced flavors, especially when grown at high altitudes.
Processing Method: Natural Anaerobic
?
The Natural Anaerobic process combines traditional natural drying with controlled, oxygen-free fermentation to create a bold and complex cup. Ripe coffee cherries are first sealed in airtight tanks or barrels, where they ferment without oxygen (anaerobically) for a set period—often several days. This environment encourages specific microbial activity, leading to the development of unique flavour compounds. After fermentation, the cherries are dried whole on raised beds or patios, allowing sugars and flavours to concentrate as the fruit dries around the seed. The result is a coffee with intense fruitiness, jammy sweetness, and rich body—often featuring tropical, boozy, or fermented notes with a distinct depth and complexity not found in traditional naturals.

About Miriam Quesada Enciso & Libardo Enciso

Miriam Quesada Enciso is a second-generation coffee producer. She inherited Finca El Guayacan from her ex-husband when they split their land. She has been cultivating coffee on the farm since 2005. Today, Miriam and her current husband, Libardo, manage Finca El Guayacan using a focus on high-quality cultivation and processing.

Cuatro Vientos is a family-owned exporter based in Colombia. Founded in 2018 by Julian & Yonatan Gonzalez and based in Huila, the company is named after the Gonzalez’s first farmnwhere the brothers spent much of their childhood.  Yonatan and Julian learned much of what they know from their father, Armando Gonzalez who was a “pergaminero,” someone who bought and sold parchment coffee. Sucafina has worked with Cuatro Vientos since 2021. 

Through their partnership with Sucafina, Cuatro Vientos is able to more effectively reach new markets. This, in turn, means they can work with more farmers and develop better programs to support their farmers.

Cuatro Vientos has 3 purchasing points in Huila: Acevedo, Santa Maria and Algeciras. These points are more than just places where they buy coffee, though. They are service hubs where farmers can access services to maintain quality and reach new markets. For Cuatro Vientos, farmers are long term partners who are focused on quality.

With these three locations, Cuatro Vientos is able to source fresh coffee year-round. In their unique position across Huila, they can tap into two alternative harvest seasons within Huila. The northern Huila harvest occurs in the first half of the year and the southern Huilaharvest happens during the second half of the year, providing high-quality coffees year round.

They also own 2 warehouses that are strategically placed in Acevedo (in Southern Huila) and Campo Alegre (in Northern Huila). The warehouses provide an array of important services to farmers. Farmers can dry their coffee, store dried parchment in silos and learn to grade and evaluate coffees in the cupping labs. 

Cuatros Vientos adds value by offering logistics and milling support to the over 30 farms that they work with. These farmers are all specialty oriented and Cuatro Vientos’ focus on specialty processing helps farmers ensure that their coffees are handled properly.

One of Cuatro Vientos’ biggest impacts is their credit line offerings. Growers need financing at the beginning of the harvest and it is difficult for them to access financing through traditional banks due to a lack of financial documentation. By providing financing through their partner, Bancolombia, Cuatro Vientos is supporting long term farmer profitability. They also provide financial education workshops that increase farmers’ financial literacy and promotes overall success.  

They also provide marketing services for farmers, helping them manage samples and tell their stories. Importantly, they act as an integral part of a two-way conversation between producers and roasters about what they’re looking for, what they can do and how they can best achieve the results they’re looking for.

Cultivation

The volcanic loam soil is nutrient-rich and excellent for growing coffee. In addition to coffee, Miriam and Libardo also cultivate plantain and yucca.

Miriam and Libardo are working on improving harvesting methods and ensuring the laborers pick only ripe, red cherry. They’re using incentives like better prices and free meals to entice good workers and reward their efforts.

Once coffee is harvested, they float cherry and remove any lightweights. The good quality cherry is then placed in sealed bags and fermented for 4 days. Following fermentation, they deliver cherry to a separate drying facility where it dries for approximately 15 days. Cherry is turned frequently to ensure even drying.

About Castillo

Castillo is a variety released by Colombia’s National Center for Coffee Investigation (CENCICAFE) in 2005. It is marked by high yield and resistance to Coffee Leaf Rust (CLR). Its dwarf size means it can be planted close together for higher per-hectare yields. Research has indicated that Castillo has a strong quality potential, contrary to popular quality assumptions about Castillo. 

Coffee in Colombia

Colombia has been producing and exporting coffee renowned for their full body, bright acidity and rich aftertaste, since the early 19th century.

Colombia boasts a wide range of climates and geographic conditions that, in turn, produce their own unique flavors in coffee. This also means that harvest times can vary quite a bit. In fact, between all its different regions, Colombia produces fresh crop nearly all year round.

The increasing focus on the specialty industry is changing the way traders and farmers do business. It is becoming more common for farmers to isolate the highest quality beans in their lots to market separately. These higher-quality lots are often sold under specific brands or stories.

Besides its wide variety of cup profiles, Colombia has quickly expanded its certification options over the past 10 years. The most common certifications available are Fairtrade, Rainforest Alliance, UTZ and Organic.

I LOVE THIS BEAN SO DO MY PEOPLE
ANYTHING BLACK WITH THIS IS DELISH

How does my coffee come packaged?

Despite some of our product images looking very fancy our coffee is packaged into a plain brown paper foiled lined bag with a Swiss WIPF degassing valve. This offers superior oxygen and moisture protection. We recommend once you crack the seal you store your coffee in AirScape containers or Weber Workshop Bean Cellars for a single dosing option.
You can also freeze/vacuum seal in small lots, then use straight away once removed from freezer.

We don't have fancy printed bags with ziplocks (more plastic), we save that cost and buy better quality green beans so you can focus on your cup quality instead of fancy marketing and artwork.
