The Ultimate Grandpa Style Tea Guide: Leaf Selection, Refills, and Dos and Don'ts
The simplicity of the method often lulls beginners into carelessness. While forgiving, the physics of extraction still apply inside a ceramic mug.
The most frequent error is excessive water heat on spring-harvested green teas. Pouring a rolling 100°C (212°F) stream directly onto tender buds like Biluochun or early spring Longjing scalds the delicate proteins, causing immediate yellowing and a bitter edge. Drop your kettle temperature to 80°C or let freshly boiled water rest in an open vessel for three minutes before pouring.
Agitation is another common trap. Never stir the leaves with a spoon, and avoid swirling the glass aggressively. Agitation dislodges the submerged bed of wet leaves, suspending tiny leaf hairs and broken particles in the upper water column. Pour smoothly against the inside wall of the tumbler. Let gravity and natural convection distribute the liquor, keeping the sediment settled where it cannot enter your mouth.
