It's our special brew. After 6 hours of distillation from the coarsely ground coffee we keep it steep between 8-12 hours.
The best way to serve is to pour 40ml from the bottle in a tall glass mix with approx 160ml water and add up to 6 standart ice cubes to maintain its texture and rich taste. 
1 bottle of concentrate cold brew makes 5 glass of cold beverage. 
After receiving the cold brew keep in the refrigerator.
