Chumushi sencha

中蒸し煎茶

Green tea

Fukamushicha

深蒸し茶

Green tea

Why these two get confused

Two of the three standard steaming depths. Most sencha sold without a descriptor is chumushi, so a first fukamushicha often reads as a fault rather than a style.

TeaHQ has written about this pair

How many seconds the leaf spent in steam, which decides whether the cup is clear and aromatic or cloudy and thick. Cloudiness in Japanese green tea is one of the most misread signals in tea: here it is the deliberate product of the steaming choice.

Steaming time
Chumushi sencha: Roughly thirty to sixty seconds — the default.Fukamushicha: Up to two minutes.
What it does to the leaf
Chumushi sencha: Some breakdown, still recognisably whole leaf.Fukamushicha: Breaks it down considerably; a lot of fine material.
What the liquor looks like
Chumushi sencha: Clear to slightly hazy.Fukamushicha: Cloudy and deep green, with sediment that settles.
What it tastes like
Chumushi sencha: Balanced — the point everything else is described against.Fukamushicha: Heavy and savoury, with much less aroma and much more weight.
How it brews
Chumushi sencha: Ordinary sencha timings.Fukamushicha: Very fast. Broken material extracts quickly, and a normal sencha steep over-extracts it.
What it does to a filter
Chumushi sencha: Passes cleanly.Fukamushicha: Clogs fine mesh. Japanese pots for this style use a wide integrated filter for exactly this reason.
Where it comes from
Chumushi sencha: The national default; most unlabelled sencha is this.Fukamushicha: Associated with Shizuoka, where the style was developed for leaf that needed more from the steam.

In summary: None of these is a grade. A cloudy fukamushi cup is not a fault and a pale asamushi cup is not weak tea — they are two ends of one processing decision, and the practical consequence is timing: if a sencha turns bitter at a steep that used to work, the new packet may simply be deeper-steamed.
