INTRO

Jairo Arcila is one of Colombia's most celebrated producers, and his experimental lots are why we keep going back. For Ultra Violet, ripe Castillo cherries are selectively hand-harvested, floated and sorted, then co-fermented with fresh blackberries before a careful wash and slow drying with close moisture control.

THE PRODUCER

Jairo Arcila farms in Quindío, Colombia, and has built a reputation as one of the country's most innovative producers—his name recognisable from other standout experimental lots including Starburst Soda, Gummy Bear and Velvet Berry.

Cofinet, the import partner working directly with Jairo and his family, keeps every lot traceable and the quality exactly where it should be, allowing his experimental co-ferments to reach roasters with full transparency and consistency.

THE PROCESS

The Blackberries Washed Co-Ferment process at Jairo Arcila's farm involves:

  • 🍒 Selective Hand Harvest — Ripe Castillo cherries hand-picked

  • 👁️ Floating and Sorting — Cherries floated and sorted for quality

  • 🫐 Co-Fermentation with Blackberries — Cherries fermented alongside fresh blackberries

  • 🚿 Washing — Careful wash following co-fermentation

  • ☀️ Slow Drying — Slow dried with close moisture control

This blackberry co-fermentation, followed by a careful wash and controlled slow drying, creates the deep, saturated berry character that defines Ultra Violet.

THE CUP

Expect blackberry and blueberry straight away, deep and saturated. A creamy, boysenberry-ice-cream sweetness carries the middle, and a soft botanical note keeps the finish composed and long. Rich, purple and quietly wild.

About this variety

Castillo is designed to produce reliable quality across Colombian growing regions. It can be clean, sweet and balanced, but the farm and processing usually tell you more about the exact flavour.

Why this one is different
  • Colombia
  • Quindio
  • Washed

In Colombia, Castillo includes regional selections intended for different coffee-growing areas. Two Castillo lots can therefore taste quite different.

Washed processing can make acidity and variety character easier to read, although fermentation and drying choices still matter.

A little background

Castillo refers to a group of Colombian cultivars developed for resistance to coffee leaf rust while maintaining useful quality and agronomic performance across different growing regions.

Classification Colombian cultivar group

Technical lineage Caturra crossed with Timor Hybrid-derived material, followed by regional selection.

Variety is a guide, not a flavour guarantee. Lot notes are more specific.
