Terroir and origins
Why tea tastes of where it grew.
Terroir is everything a place does to a tea: altitude, latitude, soil, mist, the swing between day and night temperature, and the cultivar a region has settled on over centuries. A Taiwanese high-mountain oolong and a Wuyi rock tea share a plant and a process family, and taste nothing alike. The place is the difference.

What does terroir mean for tea?
The same thing it means for wine: the sum of a place's climate, soil, altitude and growing tradition, as you can taste it in the cup. Tea adds one more variable, the cultivar, because regions breed their own plants.
Does higher altitude make better tea?
Usually slower tea, which often means better: cooler nights thicken the leaf and build sweetness and aroma. But altitude is one lever among several, and a well-made lowland tea beats a careless mountain one.
What is single-origin tea?
Tea from one garden, mountain or village, not blended across regions. It is the only way to taste terroir, which is why TEAKI's catalogue is built from single-origin teas.
