Also called “single server”, one of the most known is Hario® V60.
Preparing filter-coffee with this type of percolator first of all requires placing the specific paper filter into the filter holder, then pouring it with hot water in order to remove any smell and, at the same time, heating the percolator. Then add the roughly ground coffee into the filter and, once levelled, pour the water previously heated up to 90-95°C.
The first part of the poured water, almost double of the weight of the ground coffee, will be used for the so-called “blooming”, an operation mainly required to prepare the coffee powder for the extraction and to get a more aromatic drink. After one minute, you can pour the rest of the water until the ideal proportion between water and coffee powder is reached, in accordance with your personal taste.
After the percolation process, coffee is ready to be served.
