A pastry chef turned tea researcher, I’ve always loved tea—so much so that my passion for black tea has expanded to a love for all types of tea. I primarily purchase black tea, green tea, and herbal tea from European brands, and I enjoy integrating them into my daily life. While savoring these teas, I’m constantly exploring new ways to share information with others. My goal is to reopen the café I once had to close, where people can casually enjoy the finest tea paired with supreme desserts and light meals, by 2027.
