For seven years, Daisuke has served specialty coffees as a barista and taught hand-drip latte art seminars. Currently, at mybest, he conducts the verification for all coffee-related products and equipment, including major manufacturers such as Kalita, Hario, and De'longhi, and specialty coffee brands such as Starbucks, UCC, Maruyama Coffee, and Blue Bottle Coffee. He creates content with the motto of "making ordinary coffee more delicious" by utilizing his experience as a barista. In addition, he also operates his own coffee roastery.
