Why matcha tastes different from place to place

People often ask us why tea from different places tastes different. The answer can be short or long. The more I learn, the more I feel that what we recognise as a regional character comes from nature and the intentions of the people making the tea together.

Terroir is a way of describing this sense of place. It includes soil, climate, landscape, and human culture.

For tea, it helps to look closely. Daily changes in temperature, humidity, fog, light, and the way soil holds and supplies nutrients all affect how a plant grows. These conditions matter when producing tencha, the shaded leaf tea used to make matcha.

The differences begin in the leaf

I have been thinking about how a place may shape the physical structure of a leaf, as well as its flavour.

For example, leaves growing in misty mountain conditions may develop a different density and structure from those growing quickly in a sunnier, flatter field. Differences in water, fibre, pigments, and aroma compounds may then affect what we experience in the cup.

One tea might feel deep and rounded, with lasting sweetness and a more gradual appearance of bitterness or astringency. Another might open quickly with a clear green freshness, while its finish is shorter or its astringency more noticeable. These are possibilities I am considering, rather than a rule for every mountain or lowland tea.

With matcha, we consume the whole ground leaf. The fineness of the powder, how it stays suspended in water, and its texture in the mouth add another layer to those differences.

The tea maker responds to the leaves

A producer needs to understand how their leaves behave. Steaming stops enzyme activity, and needs to suit the leaf. Heating and drying the tencha means carefully managing moisture while preserving its aroma and taste. Stone milling requires a balance between speed, fineness, and heat.

So even the same technique may give different results with leaves from different places.

Imagine working with Uji leaves to create the roasted character many drinkers associate with some Yame teas. Or using Yame tencha to pursue a more natural, balanced style associated with Uji. The results might come close, but the starting material would still bring its own qualities. These familiar styles also do not describe every tea from either region.

To me, regional flavour seems to emerge where the leaf, soil, and weather meet the maker's understanding and interpretation.

There is another part of this story too: growers, processors, sellers, intermediaries, buyers, and drinkers all influence the styles that reach us. That is something I still want to study further.
