This is so convenient to use! Just fill the filter with your choice of ground coffee followed by filtered water. I usually do this in the evenings, that way coffee is ready to go in the morning. The instructions advise to use 80 grams of ground coffee, which I think is too strong for making iced cold brew coffee. I think anywhere from 50 to 60 grams of ground coffee might be the perfect ratio, depending on your caffeine preference. Once you are done using the coffee, you simply lift it out of the carafe and use the lid to cap it to keep the coffee fresh in the fridge. Clean up is simple. I wish I had purchased this sooner! I love it! I think this would also be a great gift for a coffee connoisseur!
