- Cool misty mornings
- Warm sunny afternoons
- Regular rainfall
- High-elevation growing conditions
These environmental factors help produce coffees with clarity, sweetness, and layered complexity. Kaʻu has become one of Hawaii’s most respected emerging coffee regions.

Harvesting & Processing
MTZ emphasizes traditional, careful post-harvest methods:
Hand Picking
Cherries are harvested by hand during the main season, typically from mid-August to December.
Wet Processing
After harvest, cherries are depulped and fermented in water tanks for around 12 hours to remove remaining mucilage before drying and further preparation.
This attentive approach supports clean, expressive cup quality.
