Japanese Iced Filter Coffee, often called "Japanese iced coffee, or just Iced Filter Coffee", is a popular method of preparing coffee that originated in Japan (surprise, surprise). It's known for its refreshing and bright flavour profile, and it's different from traditional iced coffee in that it's brewed hot and then rapidly cooled down to preserve the flavours and aromatics. This rapid cooling helps lock in the complex flavours of the coffee. This results in a fresh and vibrant iced coffee with the characteristics of the beans preserved. It's a popular way to enjoy iced coffee, especially during the warmer months. But it is also delicious at any time of year!
As mentioned earlier, flash chilling the coffee brewed using the pour-over method gives Japanese Iced Filter Coffee fantastic clarity of flavour. This makes it a unique and refreshing iced coffee experience compared to other cold coffee brewing techniques. Here's a comparison of Japanese Iced Filter Coffee with some other popular cold coffee methods:
In summary, Japanese Iced Filter Coffee stands out for its fresh and vibrant flavour, making it an excellent choice for those who appreciate the nuances of coffee. It offers a balance between a refreshing iced beverage and the complexity of traditional pour-over coffee.
Because I'm generally in the mood for a party, I will give you a recipe for making one litre. But if you want to make less, you can adjust the coffee and water ratios accordingly. You won't need anything complicated or expensive, and everything you need is readily available on fixxcoffee.com. Here's what you'll need to make an Iced Filter Coffee:
When brewing 1 litre of coffee, it's generally recommended to use 60g of coffee. However, for this particular recipe, I prefer to use 65g. The reason for this is that I only use 600g of hot water to brew the coffee, while the other 400g of water is frozen. In other words, it's ice. Since there is less contact between the coffee and hot water, I've added an extra 5g of coffee to improve extraction. A regular coarse grind works well, but a slightly finer grind would further enhance the extraction.
You'll notice the hot coffee drip onto the ice below, flash-chilling it and trapping all the deliciousness. By the time the brewing process is done, most, if not all, of the ice should be melted into the brew, giving you 1lt of ready-to-drink cold coffee—sweet and clean and packed full of your favourite FiXX flavours. What you do from here is up to you, but I would recommend straight up in a tall glass full of ice. You can, of course, add milk or sweeteners and syrups if you like, but why not try it black first. You might be surprised.
