What does hanging ear coffee mean?

A portable coffee with sealed filter bag after grinding coffee beans.

Hanging ear coffee is a freshly ground coffee, which can be brewed and enjoyed immediately. Coffee brewing is completed by drip filtration, and the acidity, sweetness, bitterness, alcohol and fragrance in coffee are perfectly reflected. As long as there is a hot water source and a cup around you, you can enjoy it conveniently. Especially suitable for home, office and travel.

Similar to a black tea bag, but wrapped in ground coffee powder, the coffee bag has hard paper hanging ears on both sides, which can be hung directly on the edge of the coffee cup. When drinking, first heat the coffee cup with boiling water, then spread the coffee bag on the edge of the coffee cup, then rinse it with boiling water with a small kettle, and the coffee liquid will be filtered and poured into the coffee cup. After brewing, throw away the extracted coffee bag and you can drink coffee, which is very convenient.
