There are many kinds of iced coffee, including the iced Americano and iced latte that sell well in many coffee shops, as well as iced pour-over, cold brew, ice drip... Regarding ice drip coffee, aside from the fact that "it's more expensive" often sparks all kinds of comparisons, its long production time and unique taste and mouthfeel also add a lot of mystery to this coffee.
Although both are coffees extracted under low-temperature water, the production steps and principles of ice drip and cold brew can be said to be completely different. Cold brew is simply cold steeping, and the method is simple and clear: just mix coffee grounds with water, then put it in the refrigerator to chill for several hours, and then filter out the coffee grounds and it's all done. Therefore, as long as you have coffee beans (grounds), anyone can make cold brew at home.
Ice drip is exactly the opposite. A standard serving of ice drip coffee first requires a specific set of equipment—an ice drip pot. The container's upper, middle, and lower layers hold ice water, coffee grounds, and the drip-filtered coffee liquid in sequence, making it a continuous multi-stage coffee extraction method.
Although there are not many requirements for the coffee beans used in ice drip, if you want to highlight fermented wine aromas and rich fruity flavors, it is recommended to prioritize fruit-forward coffee beans. Ice drip coffee made with Front Street Kenya is sweet and tart like berries, with a full juicy feel; ice drip extracted with Front Street Xipu has flavors of passion fruit and grapes; another Front Street Strawberry Candy ice drip coffee carries pink floral notes and a fermented tropical fruit character.
In addition, it is not hard to tell from the name that ice drip coffee not only emphasizes "ice," but also needs to be extracted by "dripping." Therefore, the upper pot holding the ice water must be equipped with a valve that can control the dripping of the water flow, to ensure that the coffee is in a state of extraction at all times. Finally, once the coffee liquid reaches the target extraction amount, or the ice water has all dripped into the coffee grounds, it indicates that extraction is finished. However, at this point, the coffee liquid is still not ready to drink directly. It needs to be refrigerated for a period of time to ferment and mature, so that the taste becomes rich and smooth while also full of layers.
In summary, to make standard ice drip coffee, we not only need specialized equipment, but also have to keep an eye on the water drops to maintain stable extraction, while also managing various parameters and details, and waiting through a long fermentation process. Obviously, compared with cold brew, which is "so easy anyone can do it," the production elements of ice drip coffee are much more cumbersome, which is also the main reason why few people choose to make ice drip at home.
Front Street often mentions in articles that different water temperatures can brew coffees with different flavors, and at low temperatures the astringent substances in coffee are not easily released. Like pour-over, ice drip also belongs to the drip filtration category of coffee, except that it uses ice water below 5°C as the solvent, so it can be understood as low-temperature drip coffee.
