Tech Kirin releases tate-enhancing mug

thomas · 1 Oct 2025

We have had taste-enhancing spoons and taste-enhancing chopsticks, now it's a taste-enhancing beer mug.

Kirin has developed a new mug and spoon that, instead of delivering a shock, uses mild electrical currents to enhance the taste of food by making it saltier. The "Electric Salt Cup," launched on 9 September alongside an updated version of last year's spoon, is part of the company's "low-sodium support tableware" series, which it plans to introduce to other Asian markets next year.

The mug contains electrodes in its handle and at the base. When switched on and raised to the lips, a faint current runs through the liquid inside. This draws sodium ions toward the tongue, making dishes like soup seem saltier while also heightening the sense of umami. Kirin cautions, however, that the products are not suitable for anyone under 18 or for those with implanted medical devices such as pacemakers.

The Asahi reporter turned on the mug. Starting with the weakest of three intensity levels, she held the handle and slowly brought the cup to her mouth, making sure her lips maintained contact. As the reporter sipped slowly, the umami flavor noticeably deepened, creating a richer taste. The electrical current of the strongest setting, however, was too strong and caused a metallic tang, resembling iron, to spread through the reporter's mouth, and the sourness became more pronounced. According to Ai Sato of Kirin Holdings, the product development leader, individual perception varies. Around 10 to 20 percent of people may not notice much difference. Reducing salt consumption is a challenge for those accustomed to a side dish of miso or other soups because of their generally high sodium level. However, the electric salt tableware offers the possibility of reducing salt without reducing the satisfaction of the meal. That potential was clearly felt during the demonstration.

The mug is priced at 26,950 yen ($183), including tax, and the spoon costs 24,750 yen.

Yeah right!

How does it differentially prevent bitter(ish)-tasting potassium ions (they're only slightly larger than Na+ ions and in the same period) from being 'drawn to the tongue'? Why can't under 18s use them? No pacemakers/defibrillators?

Imagine being killed by a bowl of ramen?|

. It could simply be tested by reversing the polarity of the device to repel the positive ions which would, according to them, make the contents less salty.

Somebody approached me in the gym yesterday and said, "Hey, Anil! Have you seen these new wrist bracelets that reduce 'man boobs' and produce a firmer erection?" He was genuinely thinking of buying one (I suggested he'd need 10 of them for his moobs and 'Mr Softy') and I had to lead him through the critical thinking process to debunk them.

The snake oil parallels are uncanny…

Japan's brewers have certain voluntary measures in place to limit the social harms caused by drinking alcohol. One of them is not to promote the drinking of alcoholic drinks to underage people (obviously). However, it also includes promoting anything similar to alcoholic drinks, even if it doesn't contain alcohol, such as alcohol-free beer, in the same way that candy cigarettes were around when I was a kid but are not now. A spoon that enhances the taste of beer probably comes under that category.

Since it was Kirin and 'mug' in the title, I expected it to be a mug that, you know, might make happoshu taste good.

But for this one, I guess it's 'Kirin' as a food/beverage company, rather than a beer brewer.

Act-shully, since my wife stresses over salt in our cooking, this might be good for her.

The electric cup and spoon is for substances containing sodium chloride in order to increase perception of saltiness and umami. Beer, of any sort, doesn't have much NaCl and is thus not really imbibed for saltiness/umami, so the prohibition is pointless.

They're worried about 'inducing' seizures, neurodivergence or any other spurious claim parents decide to try and sue them for!

Just buy her an ordinary, cheapo mug and spoon, glue a little strip of cooking foil (or better still that copper tape for discouraging slugs from climbing plant pots) and tell her (priming) it improves the sensation of saltiness/umami by 'attracting atmospheric neutrinos' . You'll save money, avoid being duped by 'woo-woo' and you can sneak more salt into her cooking and say, "See…atmospheric neutrinos…"
