Asamushi vs chumushi vs fukamushi
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.
What is being compared
Why these get confused
Cloudy liquor is read almost universally as a sign of something wrong — dust, poor grade, hard water. In deep-steamed Japanese tea it is the fine leaf the style is defined by, suspended in the cup.
Point by point
| Aspect | Asamushi sencha | Chumushi sencha | Fukamushicha |
|---|---|---|---|
| Steaming time | Roughly twenty to forty seconds. | Roughly thirty to sixty seconds — the default. | Up to two minutes. |
| What it does to the leaf | Leaves it intact and needle-shaped. | Some breakdown, still recognisably whole leaf. | Breaks it down considerably; a lot of fine material. |
| What the liquor looks like | Clear and pale. | Clear to slightly hazy. | Cloudy and deep green, with sediment that settles. |
| What it tastes like | Bright, aromatic, quick to fade. | Balanced — the point everything else is described against. | Heavy and savoury, with much less aroma and much more weight. |
| How it brews | Wants the longest steep of the three; the leaf gives up slowly. | Ordinary sencha timings. | Very fast. Broken material extracts quickly, and a normal sencha steep over-extracts it. |
| What it does to a filter | Passes cleanly. | Passes cleanly. | Clogs fine mesh. Japanese pots for this style use a wide integrated filter for exactly this reason. |
| Where it comes from | Associated with clear-liquor districts and delicate material. | The national default; most unlabelled sencha is this. | Associated with Shizuoka, where the style was developed for leaf that needed more from the steam. |
The short answer
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.
