As the temperature gets warmer, the heat of iced coffee gradually increases. Common types of iced coffee include iced Pour over(V60) coffee, iced espresso coffee, cold brew coffee, and iced drip coffee.But what are the differences between these four types of iced coffee? What's the difference in taste? Today, FrontStreet Coffee will share four types of iced coffee and how the baristas of FrontStreet Coffee make these four types of iced coffee.Iced Pour over(V60) coffeePour-over coffee became popular with the third wave of specialty coffee and is now an important part of the offerings of many independent coffee shops, including FrontStreet Coffee. The characteristic of Pour over(V60) coffee is that a filter cup is used to filter coffee grounds to obtain coffee liquid. The extraction process of filtering while filling with water is also very ornamental.The baristas at FrontStreet Coffee will choose 15 grams of coffee beans when making iced Pour over(V60) coffee. Different from hot brewing, the ratio of iced Pour over(V60) coffee will be 1:10, that is, 150 grams of hot water will be injected in the end and about 120 grams of coffee liquid will be extracted. This ratio is chosen because 100 grams of ice cubes will be added later to dilute it. When the ice cubes encounter the freshly extracted coffee liquid, they will begin to melt into the melted water. Choosing a lower ratio of powder to water is to avoid being overly diluted by the ice cubes.
When brewing, FrontStreet Coffee baristas will divide it into two stages. In the first stage, 30 grams of water will be injected for steaming. The purpose of steaming is to properly release carbon dioxide. Freshly roasted coffee beans mostly contain a large amount of carbon dioxide, and too much carbon dioxide will prevent the water flow from contacting the coffee powder during the brewing process. Therefore, a small amount of water will be injected into the first stage of brewing Pour over(V60) coffee to release carbon dioxide.The second stage is directly injected into the total water volume of 150 grams. The water injection method is gentle circular injection in order to extract enough flavor. The entire brewing water temperature is 90 degrees Celsius, and the grinding thickness will be slightly finer than during hot brewing. The pass rate of the 0.85mm standard sieve is about 85%, and the total extraction time is about 1 minute and 30 seconds.The brewed coffee liquid is poured into 100 grams of ice cubes, and the barista shakes it to fully mix the coffee liquid. On the one hand, the coffee liquid in the front, middle and back sections is fully mixed, and on the other hand, the ice cubes dilute the coffee liquid and let the temperature drop to low enough.The idea of making iced Americano is actually closer to that of iced Pour over(V60) coffee. They both extract coffee liquid with a higher concentration and add ice cubes to dilute it. But the difference is that iced Americano uses espresso extracted from a coffee machine. Espresso is a coffee drink that Italians use to quickly replenish caffeine. It is easy and quick to make, and the 1 to 2 ounce capacity allows people to drink a cup of espresso in two or three sips. American coffee is based on espresso and a large amount of water is added to make the coffee easier to drink.
FrontStreet Coffee baristas use an espresso machine when making iced Americano. The making method of Americano is relatively simple, with only espresso, water and ice. FrontStreet Coffee's baristas adjust the extraction parameters of espresso according to the state of the beans every day. The extraction parameters of espresso are 20 grams of coffee powder, 40 grams of coffee liquid, and the extraction time is about 26 seconds.
At this time, 300 grams of ice water mixture will be added. The ratio of ice water to espresso is 7.5 to 1.Cold brew coffee and iced drip coffee are just different from iced Americano and iced Pour over(V60) coffee. They are extracted entirely with ice water or in a low-temperature environment for a long time. The low-temperature and soft extraction parts reduce the volatilization of flavor and aroma.
Although FrontStreet Coffee currently does not sell cold brew coffee in its stores, the baristas at FrontStreet Coffee also like cold brew coffee very much. When we make cold brew coffee, we will choose 50 grams of coffee powder and mix it with 500 grams of ice water. The ratio of powder to water is 1:10. The grinding degree is relatively coarse. The passing rate of the standard 0.85mm sieve is 75%.
When making cold brew coffee, you need to prepare a container with sufficient capacity. For example, when making 500 grams of cold brew coffee, you need to prepare a container bottle of more than 600 ml.
Put the ground coffee powder and water into a container, mix it thoroughly and put it in the refrigerator to rest. The recommended low-temperature extraction time is 24 hours. Low-temperature and long-term immersion extraction is a characteristic of cold-brew coffee. This can extract relatively full iced coffee, and low temperature can gently extract the flavor and reduce the volatilization of aroma.Ice-drip coffee is similar to cold brew coffee. It is also extracted at low temperature and for a long time. Its high texture and full taste make ice-drip coffee very popular in the domestic market.
Different from cold brew coffee, making ice-drip coffee requires an ice-drip coffee pot that can produce water droplets. Ice-drip coffee is extracted by dripping ice water. In order to achieve the purpose of water dripping, the production of ice-drip coffee requires a special ice-drip coffee pot. Common ice-drip coffee pots on the market include the following structures: an upper pot that holds the ice-water mixture, a valve that controls the flow rate, a powder cup that holds coffee powder, and a lower pot that holds coffee liquid, etc. For example, FrontStreet Coffee stores are currently using Tiamo HG2713, which includes the above structure, as well as annular coil pipes.
When making ice-drip coffee, FrontStreet Coffee baristas select 60 grams of coffee beans and extract about 600 ml of ice-drip coffee, that is, the powder-to-liquid ratio is 1:10. The grinding degree should be slightly finer than that of Pour over(V60) coffee. The passing rate of the standard 0.85mm sieve is about 85%. The ground is finer and the ratio of powder to water is low. The extracted iced drip coffee is rich and full. The purpose of this is because ice will be added to dilute it when it is produced later.
The ratio of ice-water mixture is 1:1, and the valve controls the flow rate at 7 drops every 10 seconds. The entire extraction time lasts approximately 6-8 hours. The extracted ice-drip coffee will be put into a bottle and chilled for 12 hours before drinking.
The extraction time of ice-drip coffee is very long. The baristas at FrontStreet Coffee start preparing the ice-drip coffee in the morning every day and cannot finish it until the afternoon. On the one hand, the long extraction time of ice-drip coffee is because the ice water drips slowly, and it takes a very long time to extract enough coffee liquid. On the other hand, the extraction efficiency of ice water at low temperatures is extremely low. Like cold brew coffee, the extraction time needs to be lengthened to increase the taste of the coffee.
