How Does the Hario Switch Change Immersion Coffee Extraction?

The Hario Switch is an immersion dripper with a bottom valve, like the original Mr. Clever Clever Dripper, but it adds a switch lever to control water flow. That lever lets the brewer toggle between immersion and release at will, and the dripper and base detach so other drippers can be swapped in, widening the range of coffee extraction styles.

The guide walks through the Switch's structure and then demonstrates the inverted pouring method: hot water goes in first, coffee grounds are added after, and the bed steeps before release. Applied to a medium-light roasted Ethiopian ALO, this hand brew coffee meaning in practice is a more even extraction and higher sweetness than a standard pour.

Thanks to its bottom valve design, the Clever Cup allows even beginners to easily achieve professional-level extraction, earning it the nickname "beginner's coffee神器". Among the many imitations, Hario's Switch immersion dripper is especially popular. Its biggest difference from the original Mr. Clever is that it uses a switch lever to control water flow, making it more convenient to toggle between extraction modes. The Switch also has a detachable dripper and base, allowing DIY swaps with other drippers for maximum versatility. In this article, Front Street will break down the Switch's structure and operating principle in detail, and demonstrate the recently popular "upward pouring method"—adding hot water first, then the coffee grounds—using this technique to bring out a more even extraction and higher sweetness in the medium-light roasted Ethiopian ALO.

Relying on its unique bottom valve structure and intuitive, easy-to-use operation, the Clever Cup has earned the reputation of "beginner's coffee神器". Even complete novices can achieve near-professional extraction results in just a few simple steps. Because of this, the device quickly became popular after its release and gained a large following.

As the Clever Cup's popularity continues to rise, more and more brands have started referencing this concept and releasing their own "Clever Cup" products. The model designed by Hario can be said to be the most popular version besides Mr. Clever (the Clever Cup shown in the image above, originally created by EK INTL and considered the originator of the Clever Cup). A couple of months ago, Front Street shared the features of the Clever Cup, and afterward many readers left comments hoping Front Street could talk about Hario's "Clever Cup"—the Switch.

Wait a moment—Front Street knows what some of you are thinking right now! But unfortunately, this "Switch" is not that "Switch," so this article will not teach you how to brew coffee with a game console (and of course, it never will).

The Switch is an immersion dripper (i.e., a "Clever Cup") released by Hario several years ago. Its biggest feature is the ability to switch extraction modes at any time, which Front Street speculates is the reason it was named "Switch" (meaning a switch or toggle).

Whether it's the Switch or the original Clever Cup, Mr. Clever, all Clever Cups rely on a bottom valve to control water flow, allowing free switching between immersion extraction and drip extraction. The difference is that the Switch integrates water flow control into a single switch lever rather than relying on the device's own weight, making the toggle operation smoother. This is also the core difference between it and the original.

The Switch Clever Cup's structure mainly consists of two parts: the dripper body and the base with the valve system. The dripper body uses the classic all-purpose glass V60. Its size is relatively close to a standard 02 V60, but slightly smaller. Since it is positioned as a single-serving dripper, but immersion extraction requires pouring in all the hot water at once, its volume is a bit larger than a standard 01 V60.

The base connected to the bottom of the dripper is made of silicone. The internal valve system consists of a small steel ball and a transparent lever-style switch. The valve is closed by default, and the small steel ball blocks the only outlet to create a seal.

When we press the switch lever downward, the small steel ball is pushed open by the lever, and the coffee liquid flows out as the valve opens. When the lever is lifted back up (to be honest, this direction feels a bit counterintuitive), the steel ball returns to its original position and reseals the valve.

Because this design allows extraction modes to be switched without moving the dripper, coffee experts quickly got their hands on the Switch after its release and developed various extraction methods based on its characteristics. For example, Tetsu Kasuya's Devil Brewing Method was developed based on the features of the Switch Clever Cup.

Speaking of this, Front Street has to mention another highlight of the Switch Clever Cup—it's detachable. The dripper and base are not molded as one piece. Simply grip both ends firmly with your hands and pull, and the dripper separates from the base.

This design brings two benefits: first, it's easier to clean. The dripper can be removed, allowing thorough cleaning of the dead corners originally hidden by the dripper; second, you can swap drippers! This is something Front Street really likes. As long as the bottom size of another dripper is roughly the same as the original, it can be installed directly on the base, letting you DIY your own Clever Cup version. For example, the Infinite Dripper can be removed and installed directly on the Switch base to make a slower-flow version, offering quite a lot of versatility.

That's basically it! Other aspects are actually not very different from the Mr. Clever Clever Cup (such as coffee extraction). Interested friends can refer to the article "Why is the Clever Cup hailed as a 'coffee神器'?" It includes detailed introductions to three different Clever Cup extraction methods, so Front Street won't repeat them here.

But the article clearly isn't over yet. Next, Front Street will share an extraction method that experts have been loving recently: the upward pouring method.

The upward pouring method is a classic technique commonly used in siphon/AeroPress coffee (both belong to the immersion extraction category). So what is the upward pouring method? Usually, when making coffee, we first add grounds, then use hot water to wet and brew the coffee grounds for extraction. The upward pouring method, however, first pours hot water into the brewer, then adds the coffee grounds and stirs. The benefit is that it allows more even coffee extraction, resulting in higher sweetness.

Talk is useless—next, Front Street will demonstrate the specific steps of the upward pouring method! The coffee beans used in this Front Street demonstration are medium-light roasted Ethiopian ALO, with the following extraction parameters:

Dose: 17g Grind size: Ek43 setting 8, 90% passing through a No. 20 sieve Coffee-to-water ratio: 1:15 Water temperature: 95°C Extraction time: 4 minutes

First, preheat the dripper with a small amount of hot water. After preheating, release the preheating water and discard it, then close the valve and pour all the target water into the dripper. Here at Front Street, the dose is 17g, so pour in 255ml hot water. (No more than that, or it may overflow.)

After pouring the hot water, add all the coffee grounds directly and start timing.

Next, take out a stirring rod and push all the coffee grounds floating on the surface into the water and stir. About 10 stirs is enough. At this point, the purpose of stirring is to allow the water and coffee grounds to fully contact.

When the time reaches 1 minute and 3 minutes, we stir once each time. The number of stirs is also 10, but these two stirs are meant to speed up the dissolution of flavor compounds from the coffee.

When the time reaches 4 minutes, you can open the valve and let the coffee liquid release.

After the coffee finishes dripping, remove the dripper, end extraction, and start enjoying your coffee!

As Front Street said, the ALO extracted this way has quite good sweetness, a full body, and very distinct flavor notes of mango, citrus, pineapple, and more. Very nice~

But rather than brewing coffee, Front Street actually prefers using this "Clever Cup" for another thing:

Brewing tea!
