Does the Hario V60 01 or 02 Change When to Grind Coffee Beans?

The Hario V60 01 and 02 differ mainly in capacity and recommended dose. The 01 suits smaller single cups, while the 02 holds more and needs a slightly coarser grind because the larger bed and bigger water volume slow the flow and extend contact time. Grind size should be set to match whichever dripper is used.

The V60's 60-degree cone, wide filter hole, and spiral exhaust grooves shape extraction. The 02 pours more water, so a coarser setting keeps bitterness in check, while the 01 can take a finer grind. A Yirgacheffe Natural Red Cherry, brewed in three pours, shows how the two sizes behave.

The Hario V60 is practically standard equipment for every pour-over enthusiast, but what exactly is the difference between the 01 and 02? From the perspective of Front Street Coffee, this article first reviews the design origins and three core features of the V60 dripper, then takes a deeper look at the differences between the 01 and 02 in recommended coffee dose and actual capacity, and explains why the 02 dripper requires a slightly coarser grind. It then uses the Yirgacheffe Natural Red Cherry as an example to demonstrate the three-pour brewing parameters and techniques for both drippers, helping you make a more suitable choice in your daily brewing.

Anyone who has dabbled in pour-over coffee most likely has a Hario V60 dripper on hand. Quite a few friends have also asked Front Street: what exactly is the difference between the 01 and the 02? In this article, Front Street will talk about this V60 dripper that "suits everyone and every bean."

The Origin of the V60 Dripper's Name

The name V60 comes from the dripper's 60-degree conical angle. In terms of material, it has used ceramic, glass, resin, and metal over time. The latest Hario V60 dripper is made of brass, designed specifically for high thermal conductivity, to achieve better extraction through better heat retention.

Features of the V60 Dripper

1. 60-degree conical design — the source of the "60" in the V60 name. The 60-degree design allows water to flow toward the center, extending the contact time between water and coffee, resulting in a more balanced extraction.

2. Large-diameter filtering hole — by changing the height and size of your pouring, you can control the flavor of the coffee through the flow rate of the water stream.

3. The most memorable feature of the Hario V60 dripper is undoubtedly the spiral-shaped exhaust grooves. The dripper features a spiral exhaust groove design with one long and one short groove, allowing air to escape upward from all around, maximizing the expansion of the coffee grounds, better releasing the carbon dioxide from the beans during the bloom phase, and ensuring stability in the subsequent extraction.

At the same time, the spiral ridge design also serves to create compression on the water flowing down, extending the extraction path and increasing the contact time between coffee grounds and water. This avoids under-extraction caused by the large hole (which allows too fast a flow), and through the gravity of the falling water stream creates compression on the coffee grounds, forming a greater sense of layering.

What Is the Difference Between the V60 Dripper's 01 and 02?

Ultimately, it comes down to the dripper size. The 01 dripper corresponds to a brewing dose of 1–2 servings, with a practical maximum of 3–4 servings; the 02 dripper corresponds to 3–4 servings, with a practical maximum of 5–6 servings. Front Street's recommendation is: for the 01 dripper, use no more than 20g of coffee per brew; for the 02 dripper, use no more than 40g per brew. The reason is that once the dose is too large, the coffee bed stacks too thickly on the filter paper, the flow rate decreases, the extraction time is prolonged, and the flavor easily turns bitter.

Therefore, when using the 02 dripper, since the increased dose also increases the thickness of the coffee bed, the flow rate naturally slows down once the bed becomes thicker. If you brew with the 02 dripper using the same grind setting as the 01 dripper, over-extraction easily occurs. So Front Street recommends that when using the 02 dripper, you can appropriately grind the coffee a little coarser.

What Roast Levels Is the V60 Dripper Suitable For?

Front Street believes that the V60, as an essential and universally known dripper for beginners, can handle coffee beans of all roast levels. As Front Street just mentioned, the V60's rib design gives the coffee more layering. If we had to say what roast level it is best suited for, it would probably be light-roasted coffee beans. For example, Front Street Coffee's Ethiopia Natural Red Cherry coffee beans — in order to express this bean's berry-like fruit acidity, distinct fermented notes, and sweetness with clear layering, brewing with a V60 is very suitable. Next, Front Street will use the Natural Red Cherry coffee beans from the Yirgacheffe region to demonstrate brewing with the 01 and 02 drippers.

How to Brew with the V60 01 Dripper?

When Front Street Coffee brews with the V60 01 dripper, it uses the resin version, as the resin material blocks heat loss. The dose is 15g, the coffee-to-water ratio is 1:15, with a total water volume of 225g, yielding approximately 190g of coffee liquid after filtration. Grind setting: 80% pass-through rate with a 0.85mm aperture sieve. Water temperature: 90–91°C.

For the brewing technique, a three-pour method is used. The first pour is 30g of water for the bloom (twice the weight of the coffee grounds), with a bloom time of 30 seconds. During the bloom, make sure all coffee grounds are saturated. The second pour brings the water up to 125g, poured evenly and gently. After pouring, wait 10 seconds for the coffee to drain. The final pour adds the remaining water, bringing the total to 225g. Wait for the coffee to fully drain and it's ready to enjoy. Total extraction time is about 2 minutes.

How to Brew with the V60 02 Dripper?

When Front Street Coffee brews with the V60 02 dripper, it uses the ceramic version, as the ceramic material retains heat better than resin. The dose is 25g, the coffee-to-water ratio is 1:15, with a total water volume of 375g, yielding approximately 310g of coffee liquid after filtration. Grind setting: 76% pass-through rate with a 0.85mm aperture sieve. Water temperature: 90–91°C.

For the brewing technique, a three-pour method is used. The first pour is 50g of water for the bloom (twice the weight of the coffee grounds), with a bloom time of 30 seconds. During the bloom, make sure all coffee grounds are saturated. The second pour brings the water up to 270g, poured evenly and gently. After pouring, wait 15 seconds for the coffee to drain. The final pour adds the remaining water, bringing the total to 375g. Wait for the coffee to fully drain and it's ready to enjoy. Total extraction time is about 3 minutes.
