Features That Shape the Taste: Two Grinds and Three Courses

There are two ways to change the taste on the NC-A58. The first is the mill's mesh filter: which of the two filters you fit changes the grind size. The second is the course, chosen from Rich, Mild, and Strong. Together they make six combinations.

Strong is a new course on the NC-A58. According to Panasonic, it uses the boiling circulation to brew at a high temperature from the first pour, bringing out bitterness and body. Panasonic suggests it for mornings when you want something to wake you up.

The decaf bean course adjusts the bloom and extraction for caffeine-free beans. Panasonic recommends the medium-fine filter for it, and the Rich/Mild/Strong choice is not available on this course.

The brewing sequence works like this: the water is heated while it circulates, a small amount of hot water blooms the grounds, and the microcomputer then controls the temperature and flow of the water during the drip. Temperature and timing change with each course.

Features That Affect Everyday Use

Automatic Mill Rinsing

After grinding, the mill is rinsed automatically during the brew, before the bloom. Panasonic calls this "mill shower auto-cleaning."

Keep-Warm

When brewing ends, the machine switches to keep-warm. The temperature drops 30 minutes after keep-warm starts, and keep-warm shuts off after 2 hours. Panasonic says this is to reduce stewing.

Timer

Neither the official spec sheet nor the Amazon Japan listing mentions a timer. If you want to set the machine the night before and have coffee ready when you wake up, a model that lists a timer is the safer choice.

Water Tank and Iced Coffee

The water tank is removable, so you can fill it at the sink and put it back. There is also an iced coffee mode.

Check before buying

The NC-A58 makes up to 4 cups (545mL). If you want to brew 5 or more cups at once, or want coffee ready on a timer in the morning, compare capacity and timer support first.

Pros and Cons

Pros

+Two grind filters and three courses give six taste combinations
+The mill is rinsed automatically during each brew
+Keep-warm lowers the temperature after 30 minutes to reduce stewing

Cons

-No timer is listed in the spec sheet
-No water filtration
-Grind choice is limited to two filters, with no fine adjustment

How It Compares to Competitors

Here it is next to another fully automatic coffee maker at around ¥20,000, the Siroca SC-A352 Cafe Bako.

Model	Price (Amazon Japan)	Mill	Grind	Cups	Timer	Keep-warm
Panasonic NC-A58	¥21,350	Vertical mill	2 settings (swap the filter)	4	Not listed in the spec sheet	Lowers temperature after 30 min, off after 2 hours
Siroca SC-A352	¥18,700	Propeller blade	Medium-fine only	4	Yes	30 min

Prices are from Amazon Japan as of September 19, 2026.

The SC-A352 has a timer and costs ¥2,650 less. It grinds to medium-fine only and offers two tastes, Rich and Mild. The NC-A58 lets you choose between two grind settings and adds Strong and decaf bean courses. If a morning timer matters most, choose the SC-A352; if choosing between tastes matters more, choose the NC-A58.

Who Should Buy the NC-A58?

The NC-A58 suits you if you:

Want coffee from freshly ground beans but do not want to clean the mill by hand
Want a strong cup one day and a lighter cup the next
Drink decaf beans regularly

It is less suited to anyone who wants coffee ready on a timer in the morning, wants to brew 5 or more cups at once, or wants to make espresso.

Final Verdict

The NC-A58's strengths are its six taste combinations from two grind settings and three courses, and its automatic mill rinsing. Keep-warm lowers the temperature after 30 minutes and shuts off after 2 hours.

It has no water filtration, and no timer is listed in the spec sheet. On Amazon Japan it costs a little over ¥20,000 (as of September 19, 2026). If you do not need a morning timer and brew up to 4 cups at a time, it is worth a place on your shortlist.
