The Hario Switch is a deceptively simple modification of the iconic V60 that transforms it into one of the most versatile brewers available. By adding a glass ball valve to the base of a standard V60 03 cone, Hario created a device that can function as a traditional percolation pour-over, a full immersion brewer, or any combination of the two within a single brew.
The Switch entered the market in 2021 and quickly attracted attention from both home brewers and competition professionals. Its appeal lies in the ability to access immersion brewing’s forgiveness and body while retaining the V60’s clarity and brightness. Where the Clever Dripper commits fully to steep-and-release, and the standard V60 commits fully to percolation, the Switch lets the brewer choose how much of each they want, and even change their mind mid-brew.
How It Works
The Hario Switch consists of two components: a V60 03 glass dripper and a glass base with a silicone ball valve. When the switch is in the closed position (ball valve sealed), the dripper holds water like a basin, creating an immersion environment where coffee steeps in water. When the switch is opened (ball valve released), water flows through the coffee bed and paper filter exactly as it would in a standard V60 pour-over.
The ball valve is operated by a small lever on the side of the glass base. Flipping the lever opens or closes the valve instantly. This instant toggle is what gives the Switch its unique character: you can transition from immersion to percolation at any point during the brew, or switch back and forth multiple times.
The device uses standard V60 03 paper filters (larger than the typical 02 size used by most home brewers), which fit the wider 03 cone. The larger size accommodates the water volume needed for immersion brewing without overflowing.
Understanding the Brewing Modes
Full Immersion Mode
With the switch closed, the brewer functions like a Clever Dripper or French press. Water and coffee steep together for a set period, then the switch is opened to release the brewed coffee through the paper filter. This mode produces a heavier-bodied, more rounded cup with lower acidity and more uniform extraction. The paper filter removes oils and sediment that a French press would leave behind, giving immersion brewing a cleaner finish.
Percolation Mode
With the switch open from the start, the brewer functions as a standard V60. Water poured into the cone flows through the coffee bed under gravity and exits through the filter. This mode produces the bright, clean, high-clarity cups that the V60 is known for.
Hybrid Mode
This is where the Switch truly distinguishes itself. By starting in immersion mode and switching to percolation mid-brew, or by closing the switch during certain phases and opening it during others, the brewer can create a cup that blends the characteristics of both immersion and percolation brewing.
A common hybrid approach: bloom with the switch closed (trapping water for full saturation), open briefly to drain the bloom, close again for a longer steep, then open to release the final brew. Each variation produces a subtly different cup profile.
Standard Immersion Recipe
This is the most popular and forgiving way to use the Hario Switch. It produces a balanced, full-bodied cup with excellent consistency.
Equipment
- Hario Switch (V60 03 + ball valve base)
- V60 03 paper filter
- Gooseneck kettle at 93°C (199°F)
- Scale and timer
- 20g coffee, ground medium
- 320g water total
Step-by-Step
Preparation: Close the switch (ball valve sealed). Place a V60 03 paper filter in the dripper and rinse thoroughly with hot water. The closed valve will trap the rinse water in the cone. Open the switch to drain the rinse water, then close it again. Add 20g of medium-ground coffee and level the bed.
Step 1 - Pour (0:00): Start the timer and pour all 320g of water directly onto the coffee bed. Pour in gentle circles to ensure even saturation. With the switch closed, the water will pool in the cone, fully submerging the grounds.
Step 2 - Stir (0:10): Give the slurry a gentle stir with a spoon or paddle. Two or three passes through the bed are sufficient to break up any floating clumps and ensure complete saturation. Do not stir aggressively; the goal is homogeneity, not turbulence.
Step 3 - Steep (0:10 - 2:00): Allow the coffee to steep undisturbed for approximately two minutes. During this time, extraction proceeds as in any immersion method: dissolved solids migrate from the coffee particles into the surrounding water.
Step 4 - Release (2:00): Open the switch. The brewed coffee will drain through the paper filter under gravity, exactly as in a V60 pour-over. The drawdown should take approximately 45-75 seconds, for a total brew time of roughly 2:45 to 3:15.
Step 5 - Evaluate: Examine the spent bed. It should be relatively flat and even. Taste the cup and adjust future brews based on extraction quality.
Hybrid Bypass Recipe
This advanced technique uses the Switch’s toggle capability to create a concentrated immersion brew that is then diluted with bypass water for a cup that combines immersion body with percolation-like clarity.
Parameters
- 20g coffee, ground medium-fine
- 200g water for immersion steep
- 120g water for bypass (added to the cup)
- Water temperature: 96°C (205°F)
Execution
Step 1: Close the switch. Add the coffee and pour 200g of water. Stir gently. Steep for 2:30.
Step 2: While the coffee steeps, add 120g of hot water directly to the serving vessel below.
Step 3: At 2:30, open the switch. The concentrated immersion brew drains through the filter and mixes with the bypass water in the vessel below.
The result is a cup with higher extraction (because the immersion phase used a stronger ratio of 1:10) but drinking-strength concentration (because the bypass water dilutes the concentrate to approximately 1:16). This technique borrows from competition bypass brewing to achieve flavors that neither straight immersion nor straight percolation can produce alone.
Percolation-to-Immersion Hybrid
This technique starts as a V60 pour-over and transitions to immersion for the final phase.
Parameters
- 20g coffee, ground medium-fine
- 320g water
- Water temperature: 93°C (199°F)
Execution
Step 1 (0:00): Start with the switch open. Bloom with 60g of water and wait 30 seconds. This is a standard V60 bloom, with water flowing through the bed.
Step 2 (0:30): Close the switch. Pour the remaining 260g of water in a steady stream. The water pools in the cone, creating an immersion environment.
Step 3 (0:30 - 2:30): Allow the coffee to steep for two minutes with the switch closed.
Step 4 (2:30): Open the switch for final drawdown.
This method extracts the bright, acidic early compounds through percolation (the bloom phase), then shifts to the gentler, more even extraction of immersion for the remainder. The resulting cup has the clarity and brightness of a V60 in the top notes with the body and sweetness of immersion in the finish.
Variables and Adjustments
Grind size has different impacts depending on mode. For full immersion, medium grind works well because the steep time does most of the extraction work. For hybrid modes that include percolation phases, medium-fine is better to ensure adequate extraction during the flow-through portions. For pure percolation mode, use the same medium-fine setting as a standard V60.
Steep time is the primary extraction control in immersion and hybrid modes. Longer steeps increase extraction. Start at 2:00 and adjust in 15-second increments. Most coffees hit their sweet spot between 1:45 and 3:00.
Water temperature follows the same principles as other methods: hotter for light roasts (96°C / 205°F), cooler for dark roasts (88-90°C / 190-194°F). The immersion phase is more forgiving of temperature variation than percolation because the steep time compensates for extraction rate differences.
Agitation during the steep phase affects extraction intensity. No stirring produces a gentler, lighter cup. A single stir at the beginning ensures saturation. Multiple stirs during steeping increase extraction and body. Adjust based on your desired cup profile.
Hario Switch vs. Clever Dripper
Both are steep-and-release immersion brewers, but they differ in meaningful ways.
The Clever Dripper uses a flat-bottom design with its own proprietary filters. Its release mechanism is gravity-activated: placing the Clever on a mug or carafe opens the drain valve. This makes it slightly more intuitive for beginners but less flexible, since you cannot toggle between modes mid-brew.
The Hario Switch uses a conical V60 design with the manual ball valve. The cone shape and V60 filter produce a slightly different extraction profile: the conical bed drains faster and tends to produce a cleaner cup with more defined acidity. The manual valve allows mid-brew switching between modes, enabling hybrid techniques that the Clever cannot replicate.
For pure immersion brewing, both produce excellent results, and the choice often comes down to personal preference. The Switch’s advantage emerges when you want to experiment with hybrid techniques or switch between immersion and percolation based on the coffee you are brewing.
Troubleshooting
Drawdown too slow after opening switch: The grind is too fine for the V60 03 filter. Coarsen one or two settings. The 03 size drains slower than the 02 due to the larger filter surface area, so grind adjustments from standard V60 recipes are often necessary.
Weak or thin cup in immersion mode: Steep time is too short, water temperature is too low, or grind is too coarse. Increase steep time by 30 seconds or grind one setting finer.
Bitter or astringent in immersion mode: Steep time is too long or water temperature is too high. Reduce steep time by 15-30 seconds. For dark roasts, drop the water temperature.
Leaking in closed position: The ball valve may not be fully sealed. Ensure the lever is pushed completely to the closed position. Over time, the silicone seal can wear. Replacement bases are available from Hario.
Uneven extraction in hybrid modes: When transitioning between modes, stir gently after closing the switch to redistribute grounds that may have settled unevenly during the percolation phase.
Competition Use
The Hario Switch has appeared in World Brewers Cup routines as a tool for creating complex extraction profiles that single-mode brewers cannot achieve. Competitors use the toggle capability to segment extraction into distinct phases, each optimized for different flavor compound groups. The ability to brew a concentrated immersion phase and dilute with bypass water has proven particularly popular in competition settings where high extraction yields at pleasant drinking strength are the goal.
The Switch’s versatility also makes it an excellent training tool. Baristas can brew the same coffee in immersion, percolation, and hybrid modes side by side, building an intuitive understanding of how each extraction method affects the cup. This comparative tasting is one of the most effective ways to develop palate sensitivity and brewing knowledge.
