Tetsu Kasuya from Japan, in his presentation that brought the 2016 World Brewer's Cup Championship, applied to a method that we actually use frequently in training: When you pour the first, continuing and last drops of coffee brewed as drip or espresso into different cups, the flavors you get are in terms of both hardness and taste values. it gets different. Kasuya, who started with this, presented 5 glasses to the jury with different compositions after she took out 5 glasses… It seems to have worked :)))
