The Hario Immersion Switch is a dripper that combines two brewing methods in one device. Immersion gives the coffee depth and body, while pour over keeps the result clear and clean. It is rare to find these two approaches working this well in the same tool.

At the bottom of the dripper is a steel ball that closes the opening during brewing. The water and coffee steep in peace for about two minutes, and then you simply press the switch. The liquid then drains evenly into the glass server without you having to worry about pouring technique or speed. The set comes with a glass server and 40 Hario V60-02 paper filters, so you can start brewing straight away.
It measures 133 mm long and 118 mm wide. The dripper is glass, the base silicone and the switch PTS plastic. The ball is stainless steel. Hario was founded in Japan in 1921 and still makes its products in Japan. The name means king of glass, which says a lot about the brand's priorities.
This model is especially suited to comparing different coffees side by side. Because the process is repeatable and easy to control, you get almost the same result every time. You can also play with variables such as grind size, dose or steep time and see clearly how they affect the flavour.
The Hario Immersion Switch is also good for beginners. The switch removes one of the most common sources of error in pour over brewing: uneven pouring. Yet experienced enthusiasts will also find depth in it through the room for adjustment. For the office or café service in particular, it is a clear option when repeatability matters.
At its best, the result in the cup is balanced and full-bodied. The immersion stage brings out the coffee's aromas, and the filtering keeps the texture clean, with no sediment or cloudiness. In other words, you get both depth and clarity in the same cup. If you are used to manual brewers, the Immersion Switch adds a new way of making coffee at home or in the café.
Remember to use freshly ground coffee and a good coffee scale to measure an accurate dose. They are the two variables that affect the result most, whatever equipment you use. All in all, the Hario Immersion Switch is an unusually versatile dripper that deserves a place in both the enthusiast's and the professional's kit. Order it here and try it yourself.
