Soil Fertility Experiment - Cold Washed Kurume
We are excited to introduce two unique coffees from our research station in Denmark. This box set allows you to taste and learn how proper nutrient and soil management is paramount to sustain vigorous plant growth, improved vitality, and a higher coffee quality.
You will find two versions of the Kurume variety, an Ethiopian Landrace originating from the Yirgacheffe region, grown under identical conditions at our research station - the only difference being the soil fertility. A regular version of the Kurume variety, treated with our standard fertiliser regimen, and an optimised version treated with precision-fertilisers tailored to meet optimal nutrient levels and soil health based on soil- and leaf analysis over a 2-year period.
The result is a drastically improved cup with a greater diversity and intensity of aroma compounds, resulting in a more complex and amplified coffee drinking experience.

Cold Washed Kurume, Denmark
Presenting a delightful and classic expression of the Kurume variety from the Coffee Research Station in Denmark, this coffee showcases the elegance and delicacy that is so characteristic of this variety, with distinct aromas of peach and green tea, and a refined balance between floral bitterness and fruity sweetness.
Optimised Cold Washed Kurume, Denmark
In this optimised cold washed lot from the Coffee Research Station in Denmark, the Kurume variety is showcasing all its sophisticated and dense floral and fruity characters, with distinctive aromas of jasmine, apricot, and cantaloupe accompanied by a wild complexity and a coating texture as a result of an innovative approach to soil fertility and general plant nurturing.
Tonik [1], mineral concentrate
We have teamed up with Apax Lab to develop a specific water profile that enhances the flavor of our coffees to their fullest potential. This water blend is carefully crafted to balance and elevate all the unique qualities of the coffee beans.Composition: Magnesium Chloride, Sodium Chloride, Calcium Chloride, Potassium Bicarbonate, Sodium Bicarbonate
Fertiliser and Soil Quality Experiment
In coffee cultivation, maintaining optimal nutrient levels and soil balances is paramount to sustain vigorous plant growth and high-quality yields. Nutrient and soil dynamics in coffee are influenced by various factors, including soil type, climate, land management practices, and microbial activity. Understanding these dynamics is crucial for formulating effective soil fertility management strategies to improve the quality of the crop.
To demonstrate the importance of informed decision-making when talking soil fertility, we carried out an experiment. We divided the cultivation area into two halves: one received the usual fertiliser regimen, while the other half was treated with precision-fertilisers tailored to meet optimal nutrient levels over a 2-year period based on soil- and leaf analyses.
Cold Washed Process
The coffee cherries were subjected to an initial cold storage period of 48 hours at 8°C. This gentle chilling process preserves and intensifies the coffee’s aromas without inducing fermentation, thereby safeguarding its natural taste profile. Subsequently, the cherries were depulped and underwent thorough washing and drying at low temperatures in a pressurized, rotating tumble dryer. This meticulous drying procedure ensures uniformity, resulting in a clean and crisp final product.
Poma Research Station
Our Coffee Research Station was established six years ago in a climate-controlled greenhouse in Sjælland, Denmark. Within this greenhouse, we manipulate environmental factors based on algorithms that mimic plant processes. This allows us to study how coffee trees react to climate change while also maintaining a stable environment for investigating the impact of farming practices.

PREPARE BREWING WATER
We have teamed up with Apax Lab to develop a specific water profile that enhances the flavor of our coffees to their taste fullest potential. This water blend is carefully crafted to balance and elevate all the unique qualities of the coffee beans.
To prepare, simply add 3.0g of the mineral concentrate to every 1 litre of high-quality demineralised or distilled water
Then give it a good shake to dissolve any remaining crystallized solids.
This curated mixture will result in a mineral concentration of 90 parts per million (ppm) of perfectly balanced mineral compositions, optimising the brewing conditions for an exceptional coffee experience.
BREWING GUIDE
We recommend resting our coffees for at least 10 days after the roast date, and we often find our coffee the most expressive within 3 weeks after roast date.
Our recipe is using 13 grams of coffees to 200 grams of water. A coarse grind size approximately 900 micron. Brewing temperature 92C. Our brewing pattern is four 50g circle pour every 40 seconds. Total brew time is approximately 3 minutes.
0:00 50g circle pour
0:40 50g circle pour
1:20 50g circle pour
2:00 50g circle pour
Please enjoy!!
