Okumidori

A late-budding Yabukita descendant widely used for matcha and gyokuro because it holds colour well under shading and harvests after the main sencha rush, spreading a producer’s labour.

Where it sits in the botany

Okumidori is recorded under Camellia sinensis var. sinensis, the variety group one level above cultivar. It is associated with Japan, which is where it was selected or is most widely planted rather than the only place it grows.

Also transliterated as: okumidori.

What the plant is like

Its late season is an agronomic virtue rather than a flavour one, but it is why so much single-cultivar matcha is Okumidori.

Why a grower plants it

Yield, hardiness, when it buds, what it resists and whether a machine can cut it. This is the half of a cultivar’s identity that decides what is actually in the ground, and it is usually left out of writing aimed at drinkers.

Okumidori's value is a date on a calendar. Budding roughly a week to ten days after Yabukita, it lets a producer who also grows Yabukita run one picking crew, one steaming line and one drying line across two harvests instead of trying to process everything in the same few days — the constraint that actually limits quality on a Japanese tea farm at peak season. It is cold-hardy, holds chlorophyll well under the two to three weeks of shading that tencha requires, and its late budding also carries it past the worst of the late-frost window.

What it does in the cup

Deep green, mild, with a soft grassy sweetness and restrained astringency. It is often described as less complex than the classic Uji matcha cultivars and more forgiving, which is a fair summary of why it works as an everyday single-cultivar matcha.

How much of this is really the cultivar?

Matcha is the category where cultivar is claimed loudest and shading does most of the work. Two to three weeks under cover collapses astringency and raises the amino-acid-driven savoury character in any cultivar, and the difference between shaded and unshaded leaf from the same bush dwarfs the difference between two shaded cultivars. Grinding matters next — stone-milled particle size changes texture and perceived sweetness measurably. Single-cultivar matcha is a real and interesting thing to sell, but the honest framing is that it isolates a small residual on top of two much larger effects.

Cultivar, growing site and processing all shape a cup, and the cultivar is very often the smallest of the three. It is also the one that fits on a label, so almost every commercial incentive runs toward overstating it. This section is on every cultivar page that has been reviewed for it, including the ones where the honest answer is “less than you would think”.

What it is usually made into

The categories this cultivar is typically processed into. It is a statement about common practice, not a limit — processing decides the category, and a cultivar can be taken down more than one route.

Green tea — Tea whose oxidation is halted early by heat, keeping the leaf green and the cup fresh, vegetal or marine in character.

Written comparisons

Where TeaHQ has set this cultivar against something it is routinely confused with, and argued the differences out in full.

Asahi vs Okumidori for matcha — The two ends of the matcha cultivar question. One is grown regardless of cost for the texture of thick tea; the other is grown because its late season fits the harvest calendar, and it ended up making a great deal of the single-cultivar matcha on the market.
Yabukita vs Saemidori vs Okumidori — Three Japanese cultivars that account for a great deal of what reaches a drinker, chosen for three different reasons: national reliability, premium sencha character, and a harvest date that spreads a producer’s labour. Only one of those reasons is about flavour.
