We sourced this stunning irange gesha from the talented Luz Ángela Rojas, who left her fast-paced career to return home and rejuvenate her family's coffee farm. Her passion and dedication to coffee create beautiful results, and we're delighted to share five (and counting!) lots from her this year. You can read a bit more of her story below from our importing partners Mi Cafe:
The project is entirely family-run, and everyone involved is more motivated than ever to continue learning and taking their coffee to new horizons. Ángela, with her experience, dedication, and vision, has transformed the family legacy into a model of innovation within coffee farming, never losing sight of the essence of what it means to work the land and the coffee.
PROCESS
1. Harvesting: This is carried out ensuring a minimum of 90% ripe cherry.
2. Floating: This ensures the removal of green, overripe, and dry cherries.
3. Oxidation: This is done in food-grade plastic drums for 24 hours.
4. Pulping: The cherries are pulped dry.
5. Oxidation after pulping: For 24 hours in order to remove the mucilage. The
coffee is then washed at temperatures of 45°C, creating a thermal shock.
6. Fermentation: For 62 hours at temperatures below 25°C with specific yeast.
7. Fermentation completion: After 62 hours, the coffee is washed at
temperatures of 5°C to seal the fermentation.
8. Drying: After the 62 hours of fermentation, the coffee goes into drying, which
is carried out for 76 hours at average temperatures of 40°C.
9. Stabilisation: This is done in grainpro-type bags

Temperature
Temperature
For pour-over filter methods, aim for the mid 80’s. We are aiming to preserve the sweetness of these coffees. Espresso, aim for lower 90’s.
Ratios / dose / bloom
Ratios / dose / bloom
Pour over:
Larger doses, smaller water ratios.
Initiate a bloom with minimal water, leave for up to a minute then start your pulse pours to the desired amount.
Espresso:
For larger doses, aim for a slightly larger yield than a 1:2 ratio but again cater to your taste. Use a pre-infusion if possible. Aim for an extraction in the mid-20 seconds.
Rest periods
Rest periods
Please ensure a rest period of at least 3 weeks for ALL brew methods; each coffee will be different in terms of rest needed. All our coffees will benefit from a substantial rest period of anywhere from 3-6 weeks (!) Ideally, you will grind what coffee you need and not keep pre-ground coffee for any length of time. Espresso generally needs a longer rest period than filter coffees, to fully de-gas and settle.
Freezing
Freezing
Please don’t freeze our coffees, it’s largely to do with the nature of the rest periods needed to develop profiles. As soon as a coffee is frozen, the development stage stops.
our process
we roast coffee in Livingston, near Edinburgh. Our roaster of choice is a typhoon fluid bed roaster. All electric.
all our coffees are rested before selling, to ensure they have developed fully before brewing. Optimal drinking is around the 3 week past roast date mark, although each coffee is uniquely different.
Coffee Info
Good to know
Roast Dates
We roast our coffees fresh every week so they can be enjoyed at their best – after a short rest. Following roasting, beans release CO₂ and their flavours gently settle, which is why we recommend letting them rest before brewing. For filter methods (V60, Chemex, Aeropress, batch brew), we suggest using the coffee from around 3–14 days after roast, with a sweet spot of 5–10 days. For espresso, we recommend 7–21 days, with lighter roasts often shining from 10–16 days. Store your coffee in a cool, dark place in a sealed bag or airtight container, and you’ll taste the clarity, sweetness, and balance that proper resting brings.
