Compare two teas

Side by side across seven dimensions. There is no verdict and no winner — the purpose is to understand the difference, not to be told which to buy.

Fukamushicha

深蒸し茶

Green tea

Asamushi sencha

浅蒸し煎茶

Green tea

Why these two get confused

Opposite ends of the steaming axis, and the difference in the cup is dramatic. Cloudy dark liquor is not a sign of quality, it is a sign of deep steaming.

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
Fukamushicha: Up to two minutes.Asamushi sencha: Roughly twenty to forty seconds.
What it does to the leaf
Fukamushicha: Breaks it down considerably; a lot of fine material.Asamushi sencha: Leaves it intact and needle-shaped.
What the liquor looks like
Fukamushicha: Cloudy and deep green, with sediment that settles.Asamushi sencha: Clear and pale.
What it tastes like
Fukamushicha: Heavy and savoury, with much less aroma and much more weight.Asamushi sencha: Bright, aromatic, quick to fade.
How it brews
Fukamushicha: Very fast. Broken material extracts quickly, and a normal sencha steep over-extracts it.Asamushi sencha: Wants the longest steep of the three; the leaf gives up slowly.
What it does to a filter
Fukamushicha: Clogs fine mesh. Japanese pots for this style use a wide integrated filter for exactly this reason.Asamushi sencha: Passes cleanly.
Where it comes from
Fukamushicha: Associated with Shizuoka, where the style was developed for leaf that needed more from the steam.Asamushi sencha: Associated with clear-liquor districts and delicate material.

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.
