El Vergel, Tolima, Colombia – Natural Koji Bourbon

– “A rare and experimental Koji Oryzae processed Bourbon lot from our dear friends Elias and Shady Bayter”. 

What to expect in the cup

Watermelon, Papaya, Berry kombucha. Sweet, floral and juicy with outstanding balance and complexity.


This a brand new and unique experimental Koji process used a special yeast called A. Oryzae to trigger different chemical reactions during the fermentation, enhancing the Amino Acids, a big factor in the Maillard reaction during roasting. The result is a balanced cup of coffee with a syrupy body, sparkling acidity and an overall round sweetness.
El Vergel is situated in the mountainous department of Tolima, El Vergel sits atop the inactive volcano on the Piedra Grand Trail – benefitting from a unique microclimate and localised volcanic terroir.The farm is managed by the Bayter brothers, Shady and Elias, and their mother, Marta. The brothers have been farming since their childhood, following their parent’s footsteps, who started growing avocados and conventional coffee back in 1995. Since then, El Vergel became known as one the largest producers in their region, leading them to provide economic growth to hundreds who worked with the farm. El Vergel Estate has been producing a variety of coffees and experimenting with new and innovative processing techniques based on the coffee’s density, genetics, and other characteristics.
