This twin valves system can provide good options you for making delicious coffee.
-. Coffee: 60g

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 with hot water before & after using.
Put the coffee ground in this coffee tube.
Hit this coffee tube slightly to level coffee grounds fairly.
*We don’t need to use tamper dditionally.
In case of using tamper, the density is high 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.
*we don’t need to use an additional cloth filter on the top of this coffee tube.
The twin valve system helps to moisten coffee grounds fairly.
Check this coffee grounds until these are moistened completely.
** It takes around 40mins~60mins
** Depending on grind size and roasting type, the amount of water can be adjusted.
Tip! And then close these two valves fully and stand still for 30mins ~60mins, like “additional brewing time (Pre-infusion) ”
And then open two valves properly.
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 coffee is being extracted at the same time.
These coffee grounds should be kept moist while extracting adjusting the second valve.
Please pay careful attention to adjusting twin valves!!
You’ll get much more delicious coffee!!
It takes about 4hrs.
Depending on grind size and type of coffee, you can adjust faster or slower.
If you can adjust the twin valves properly, you can get rich & strong coffee concentrate even smaller time.
