Because of the high quality of hanging coffee and the convenience of brewing operation, more and more people like to keep a few bags of Front Street hanging coffee at home or in the office. As the seasons change, many areas have begun to enter the rhythm of summer. In addition to hot brewing, hanging coffee bags can actually be made into cold brewed iced coffee! In this article, let’s talk about how to make iced black coffee using hanging ear coffee pods.
Where did the design inspiration for the ear-hanging coffee pods come from?
The design of the hanging ear coffee is inspired by the lanyard tea bag. The pre-ground coffee powder is packed in a non-woven bag with a paper card. Then when brewing, just snap the card on the cup to brew coffee. The difference between hanging ear coffee bags and lanyard tea bags is that hanging ear coffee extracts coffee through drip filtering, while lanyard tea bags extract tea through steeping.

What is the difference between drip filter extraction and immersion extraction?
Front Street used coffee extraction as an example. Drip brewing is carried out through water injection and filtration, so the water injection speed of drip brewing (water flow size, water injection height, etc.) will affect the filtering speed and the flavor of the coffee. The biggest feature of drip brewing is that the coffee extracted in this way will be rich in layers. The immersion method extracts coffee powder by directly soaking it in water and then filtering the coffee grounds. The biggest feature is that it can more fully extract the flavor substances of the coffee, and the body of the coffee will also be greatly improved.
Therefore, hot brewed coffee belongs to drip extraction coffee, while cold brewed coffee belongs to immersion extraction coffee. The former is to quickly extract the flavor substances of coffee through high temperature, and the latter is to slowly soak out the flavor substances of coffee at low temperature.
The difference between high temperature extraction and low temperature extraction
Temperature affects the rate at which the oils, acids, and sugars in coffee break down. Depending on how quickly this process occurs, the aroma, taste, and texture of the coffee vary greatly. This is why different extraction methods can produce different qualities of coffee.

The advantage of high-temperature extraction is that it can quickly extract the flavor substances of coffee, causing the tannic acid in the coffee to quickly decompose into pyroacid, resulting in sweetness and sourness, which is the process of releasing the flavor of coffee that is often said on the street. The disadvantage of high-temperature extraction is that it easily causes the coffee flavor to be completely released, and then begins to release the taste of the woody fiber of the coffee beans, which is what we often call unpleasant flavors such as miscellaneous flavor and woody flavor.
Cold brew uses low-temperature immersion extraction to reduce the volatilization of coffee flavors under low-temperature conditions, and store the coffee aroma in the coffee liquid as much as possible. When you drink it into your mouth, the temperature of the coffee liquid rises, and the aroma contained in the coffee liquid suddenly explodes, allowing coffee drinkers to feel the strong aroma at the back of the tongue in their mouth. This sudden burst of aroma will give people a great sense of happiness. The disadvantage is that it takes a long time to make cold brew coffee. It takes at least 8 hours to make cold brew coffee.
How to make cold brew coffee with ear-mounted coffee pods?
This time, Front Street used Honduras Sherry coffee bean hanging coffee bags from FrontStreet Coffee as a demonstration. Honduran sherry coffee beans have always been a favorite among Front Street fans. The coffee beans are fermented at low temperature for one month in aged whiskey sherry barrels, absorbing the aroma of the whiskey in the oak barrels, making the coffee beans taste like whiskey. The hanging coffee pods made from this coffee bean have a rich whiskey flavor when brewed, and the smooth taste and aroma of vanilla cream make people have endless aftertaste.
Preparation materials: two bags of Front Street hanging ear coffee (net content of each bag is 10g), a clean container with a lid, ice water. Front Street recommends a ratio of 1:15 for making cold brew coffee, which means that two ear-hanging bags need to be soaked in 300ml of ice water.
How to make cold brew coffee in ear-hanging bags: First, disassemble the ear-hanging coffee bag, pour the coffee powder into a clean container with a lid, and keep the ear-hanging bag. Then add the recommended proportion of ice water to the container, cover the lid and shake it until the coffee powder and water are fully soaked, then put it in the refrigerator for 8-12 hours or more and not more than 24 hours for low-temperature extraction. After the extraction is completed, hang the reserved ear-hanging bag on the cup, pour the cold brew coffee into the ear-hanging bag and filter it.


How to enjoy filtered cold brew coffee?
The concentration of cold brew coffee produced with a ratio of 1:15 can reach a balanced flavor, so it can be tasted directly. If it still feels rich, you can add ice cubes, purified water, or milk to dilute it and taste it.

How long does cold brew coffee last?
Even if the coffee liquid is in a sterilized container, Front Street does not recommend storing it in the refrigerator for more than 72 hours. After all, low temperature only suppresses bacterial growth, but cannot prevent it.
