The Rise of Grandpa Style Tea: How a Humble Daily Habit Went Global
By Sophia Al-Mansoor
Not every tea handles continuous steeping equally well. Finely broken leaves, tea bags, and highly astringent tea styles quickly turn mouth-puckering and bitter if left in hot water without straining. Success depends entirely on choosing whole-leaf teas that naturally possess balanced chemical structures.
Green tea brewing shines under this method, particularly whole-leaf Chinese varieties such as Longjing (Dragon Well), Biluochun, and Anji Bai Cha. These teas are rich in L-theanine and savory amino acids, which diffuse gradually into lukewarm and hot water. For green teas, water temperature control remains crucial: pouring 175°F to 185°F (80°C to 85°C) water preserves sweetness and prevents vegetal scalding.
Large-leaf roasted oolong tea leaves, particularly strip-style varieties like Wuyi Rock Tea (Da Hong Pao, Rougui) and Dancong oolongs, also excel in a heatproof glass mug. Their structured roasting reduces raw bitterness, while their robust physical frames unfurl slowly across multiple refills. Ball-rolled Taiwanese oolongs unfold layer by layer over several hours, transforming the flavor from mineral to floral across four or five top-offs.
Conversely, avoid dust-grade black teas, broken orange pekoes, or delicate Japanese steamed greens like Fukamushi Sencha in this format. Heavily steamed or finely processed leaves fragment rapidly, clog your teeth, and flood the infusion with unbuffered tannins within three minutes.
