Why us
Threshing defines the final flavor of coffee
01
The Process
The threshing process
Separate the grain from the parchment without losing quality
Hulling is the stage that separates the green bean from the dry parchment. A poorly calibrated huller breaks the bean, affects density, and reduces the commercial value of the lot. At Green Hills, we calibrate each lot according to its origin, varietal, and process.
- Pre-cleaning by density before threshing
- Threshers with monitor for real-time control
- Screen size selection (14/15/16/17/18)
- Physical-sensory report per lot

Teams
Technology
Industrial threshers + quality monitors
We operate industrial equipment for processing large volumes and laboratory threshers for samples and micro-batches. Each batch is monitored with humidity sensors and optical sorters when applicable.
- Industrial capacity for batches from 500 kg
- Sample hulling from 250 g for analysis
- Optical sorter for visible defects
- Vacuum packaging available upon request

Sensory quality
Physical analysis and SCA cupping per lot
Each threshed lot undergoes physical analysis (moisture, defects, density, screen) and professional cupping under SCA protocol. You receive a detailed report that you can share with your buyer or final roaster.
- Post-threshing moisture analysis (10–12%)
- Primary and secondary defect count
- SCA cupping with documented sensory profile
- Lot traceability with unique code

Guía técnica de trilla
La trilla es el punto donde un lote gana o pierde su valor de exportación. Esto es lo que revisamos en cada lote que entra a nuestra planta de Itagüí, y por qué importa.
¿Por qué es crucial la trilla del café para la exportación?
El proceso de descascarillado retira el pergamino que protegió al grano durante el secado y deja el café verde listo para viajar. Ningún comprador internacional evalúa café en pergamino: lo que se cotiza, se cata y se embarca es el grano trillado, clasificado y con la humedad bajo control.
Por eso los beneficios de la trilla del café son directamente comerciales. Una trilla bien calibrada conserva la densidad del grano, reduce el partido y permite separar el lote por criba, que es el lenguaje con el que un importador define y paga un contrato. Una trilla mal calibrada convierte café de especialidad en pasilla en cuestión de minutos.
- Humedad estabilizada entre 10 % y 12 %, el rango que exige el mercado de exportación.
- Clasificación por criba 14 a 18 para homogenizar el lote y fijar precio.
- Conteo de defectos primarios y secundarios documentado por lote.
- Grano listo para catación SCA sin manipulación adicional.
Estándares de calidad en Green Hills Coffee
Aplicamos el mismo protocolo a un microlote de 250 g y a un contenedor completo. Cada lote entra con inspección, pesaje y registro de origen, pasa por pre-clasificación de densidad antes de tocar la trilladora, y sale con un reporte físico-sensorial y un código único de trazabilidad.
El control no termina en la máquina: medimos humedad después de trillar, pasamos el café por selector óptico cuando el lote lo requiere y catamos bajo protocolo SCA. Nuestros lotes de especialidad salen desde 84 puntos SCA, y ese puntaje queda documentado en el reporte que puedes enviarle a tu comprador o a tu tostador final.
Diferencias entre trilla convencional y especial
La trilla convencional está diseñada para volumen: la máquina corre rápido, el lote se homogeniza y se acepta un porcentaje de grano partido porque el destino es el mercado interno o el café industrial. La prioridad es la tonelada por hora.
La trilla de café especial invierte la ecuación. Bajamos la velocidad de alimentación, ajustamos la presión según el varietal y el proceso —un natural y un lavado no se trillan igual— y corremos el lote solo, sin mezclarlo con otros. Antes y después de cada lote especial purgamos el equipo para que no quede grano del anterior. Es más lento y más costoso por kilo, y es la única forma de que el perfil construido en la finca llegue intacto a la taza.
Cómo garantizamos la integridad del grano
La calidad del grano después de la trilla se mide, no se promete. Comparamos peso de entrada y salida para calcular la merma real, revisamos el porcentaje de partido sobre muestra y verificamos que la densidad se mantenga dentro del rango del lote original.
- Trilladoras con monitor para corregir la calibración en tiempo real.
- Purga del equipo entre lotes para preservar la trazabilidad.
- Muestra de control antes de liberar el lote completo.
- Empaque al vacío o Grain Pro al cierre para sostener la humedad.
Si el lote va a exportación, ese mismo reporte sirve como soporte documental frente al importador.
Testimonials
What producers say
The physical-sensory report opened doors for us with a buyer in South Korea. Green Hills' milling is the most consistent we've used in five years.
They mill microlots with the same care as a large industrial producer. For us, who sell specialty coffees by auction, that is invaluable.
Comprehensive service, professional team. On-site SCA cupping saves us two weeks of logistics every harvest.
Frequently asked questions
We answer your most frequent questions
What is the minimum volume for industrial threshing?
The minimum volume is 500 kg of dry parchment coffee. For smaller volumes, we offer a sample hulling service starting from 250 g, ideal for quality evaluation.
Do you hull conventional and specialty coffee?
Yes. We calibrate the equipment according to the type of batch to avoid mixing and preserve traceability.
Does the service include SCA cupping?
SCA cupping is included in the sample hulling service and the comprehensive service. For industrial hulling, it is optional.
Where are you located, and do you receive coffee from outside Antioquia?
We are in Itagüí, Antioquia (Cra. 54 #79-30). We receive coffee from any region of Colombia. We coordinate lot entry via email or WhatsApp.
How long does it take to deliver the threshed batch?
Sample hulling: 48–72 h. Industrial hulling: 5–10 business days. Full service with roasting and packaging: 10–15 business days.
