Proprietary Production System 

EXTRACTION TECHNOLOGY
COLD BREW

We apply a ‘Spray-Filter system' using our patented extraction equipment. Water is evenly sprayed in a mist form to extract cold brew coffee with a clean and vibrant taste.

ESPRESSO

By applying pressure to our existing cold brew extraction method, we extract coffee at a higher concentration. This creates a concentrate with a bold and intense flavor, similar to espresso coffee.

SPECIALIZED SYSTEMS
Clean Room System

HANDIUM's extraction facility employs a clean room system that automatically manages airborne particles, temperature, and humidity at optimal levels. HEPA filters that remove airborne particles and UV sterilization lamps are installed to ensure maximum product hygiene.

Water Purification System

Water used for cold brew extraction undergoes purification and sterilization. Only purified water that has passed through two micro filters, activated carbon filters, and UV sterilization is introduced into the production line. Since 2022, we have completed facility upgrades to extract cold brew using mineral-rich deep sea water.
