COLDBREW

1. Cold Brew is an extraction style, not a cold beverage

2. It is extracted at cold temperature, i.e. below 20°C

3. It takes longer extraction times, i.e. over two hours

4. Extraction depends from

• Dosage (Brew ratio) • Temperature of the water • Water-composition (hardness, …) • Turbulence • Time of Extraction • Grinding level, particle size and surface, dust
