Put the cloth filter in this bottom of coffee tube evenly.
At this time, “wet” cloth filter helps to place easily.
*This cloth filter is reusable.
* Make sure to clean this filter before & after using.
To sterilize, you’d better cleaning it with hot water.
Hit this coffee tube slightly to level coffee grounds fairly. It helps to be steeped from top to bottom.
*We don’t need to use tamper additionally. In case of using tamper, the density will be much higher and it hinders distributing water vessel fairly.
Open the first valve properly. At first, you can adjust the water drip speed about one drop every second.
*The amount of drops can be slower or faster as you wish.
*we don’t need to use an additional cloth filter on the top of this coffee tube. The double valve system helps to moisten coffee grounds fairly.
Please let the “Pause” for an hour. It means, you can close these two valves temporary. The additional brewing time influences their taste.
After this additional brewing time(Pre-infusion), open the second valve fully or less.
** You can create the own taste based on roasting type using this second valve!!
Tip! You can adjust the amount of cold water using the first valve and the amount of coffee drops using the second valve. Water is being distributed continually while offee is being extracted at the same time.
Please make sure that you can soak this valve in hot water for 30 min. to remove some used coffee grounds between the valve.
The whole extracted time (brewed) time will be between 6hrs and 8hrs in case of 3,200ml of water. It really depends of what kind of coffee you use such as roasting type, grind size and origination. You can choose what you like.
Enjoy your colddrip world!!!
