Detergent for kitchen grease, sanitizing spray for wiping down tables, chemicals for preventing mold. Have you found yourself buying a different bottle for every single purpose? And on the back of every one of them, there's always a warning: "Avoid contact with eyes," "Caution: do not ingest."
But "Pastoriser 77," made by Japanese sake brewery Dover Brewery, turns that conventional wisdom on its head. It's an extremely high-purity alcohol formulation, yet it's classified as a "food additive." In other words, not only can you use it to sanitize cutting boards and knives—you can spray it directly onto bread, sashimi, or your bento lunch with absolutely no problem.

The "77" in the product name refers to its 77% alcohol content. This is the golden ratio that delivers maximum sanitizing and antibacterial effect.
Thanks to this high-concentration alcohol, its disinfecting power reaches medical-grade levels. On top of that, it's infused with high-purity catechin extracted from green tea, so its antibacterial action continues long after the alcohol has evaporated. Because it uses pure water meant for sake brewing and brewing-grade alcohol, it never compromises the taste or aroma of food. The "secret weapon" professional patissiers use to keep their cakes fresh is something you can use at home, exactly as it is.

Pastoriser's brilliance isn't limited to sanitizing. High-concentration alcohol also acts as a powerful solvent that breaks down grease.
Splattered grease around the stove, the sticky film on your range hood—just spray Pastoriser on these spots and wipe them away, and you'll get a squeaky-clean finish with no second wipe needed. It's also perfect for cleaning the inside of your fridge or microwave. In places where you'd rather not use detergent, this is "safe even if it accidentally gets into your mouth," so you can spray as much as you like without holding back.

In humid Japan, mold is the greatest enemy. Pastoriser powerfully suppresses mold growth.
- Mochi and bread: A quick spritz before storing can delay mold by days or even weeks.
- Jam jars: After opening, give the inside of the lid a quick spray before closing—it'll keep your jam fresh longer.
- Bento lunches: Just before closing the lid, mist it over the entire spread of side dishes. It becomes the ultimate preservative against summer spoilage.
- Sink drain catchers: Spray it as the finishing touch when you clean, and you'll prevent that nasty slime and keep fruit flies away.

A surprisingly great use is for "window cleaning" and "mirror polishing." Regular detergents and damp cloths inevitably leave behind white streaks, but Pastoriser is so highly volatile that it dries the instant you wipe.
No streaks left behind whatsoever—just a crystal-clear finish. As a bonus, it forms an antibacterial catechin film, making it harder for new grime to stick.
