Over the past few days I have been using a Japanese copper filter (Kalita) with its own crinkly (very crinkly) filter paper, rather than my more usual (and somewhat less time consuming) ceramic Hario dripper with which to prepare my morning filter coffee.
The main reason for the, to be honest, was that had finished one of the packets of paper filters for the Hario dripper and decided to use some of the considerable quantity of crinkly filter paper I had for the exquisite Kalita copper filter dripper, instead.
This means slower and more precise pouring, and taking a bit more time with the preparation of the coffee.
I will say that the aroma of the coffee, when prepared this way, is absolutely divine. Aromas of mocha, and coffee, and chocolate.
A very agreeable and enjoyable way in which to prepare coffee. But not one, I suspect, that I would readily prepare if dashing out the door to catch a train, or plane, or bus, or taxi.
