The Hario V60, available in various materials and colors, is a popular choice for coffee lovers who appreciate the art of pour-over brewing. While it can bring great satisfaction, every V60 user has likely experienced the frustration of a clogged filter.

As you are preparing for that much-anticipated morning cup, you might notice your coffee grounds morphing into a swamp-like state, refusing to drain into the decanter. A troubling sight, indeed. However, rest assured, you are not alone, and we have solutions!

Let's delve into the potential culprits behind the clogging in your Hario V60 and discuss how to overcome this coffee brewing hurdle.

Why Does Clogging Happen?

Often referred to as “choking” or “stalling,” clogging is a common occurrence in manual brewing. Before solving the problem, it's crucial to understand its origins. Below are five probable causes of a clogged V60 filter.

The Pouring Technique

Pour-over brewing is not just a process; it's an art that requires precision. After lining the V60 with a wet paper filter and adding the grounds, you pour boiling water over the bed of coffee. Here, ensure that you pour gently and slowly in a circular motion.

Pouring too swiftly or vigorously can agitate the coffee bed, releasing fine particles that may clog the filter, and disrupt your brewing process, leaving you with an unsatisfactory brew.

Grind Size Consistency

When it comes to the V60, the size and consistency of your coffee grind matter. It's best to use a burr grinder that offers a consistent grind size for your beans.

If your filter is frequently clogging, you might be grinding your coffee too fine. Blade grinders and lower-end burr grinders often generate more fine particles, leading to clogging. If buying a professional grinder isn't an option, try a coarser grind size. Note, however, that coarser grinds may lead to a lower extraction yield, which can be counterbalanced by tweaking your brew ratio.

Filter Quality

The market is rife with a variety of paper filters for drip coffee. However, not all filters are made equal. The material, shape, and size of the filter can impact your brew's quality.

Hario paper filters, especially designed for a V60, are typically a great choice. They are tightly woven and absorbent, helping collect oils and sediment effectively. Feel free to experiment with different filters like the unbleached V60 filters or the Niveaya V60 Filter to find your perfect match.

Type of Coffee Used

Certain types of coffee, specifically dense, light roasted coffees, can contribute to clogging. These beans, grown at high altitudes and lightly roasted to retain their unique flavors, tend to shatter when ground, producing more microparticles. These microparticles can then block the filter, slowing the drawdown and potentially altering the coffee's flavor.

Though challenging, it's not impossible to create a good pour-over with these beans. However, you might need to consider other coffee varieties for your V60.

V60 Condition

If you've ruled out the previous causes, your V60 itself might be at fault. Look for any visible cracks, misshaping, or other defects that might prevent a smooth drawdown. If your V60 is faulty and under warranty, contact your supplier for a possible replacement. If it's damaged due to use, it may be time to get a new one.

Wrapping Up the Clogging Conundrum

Clogging in the Hario V60 can be frustrating, but it's usually a minor obstacle that can be surmounted with a bit of troubleshooting. Start by identifying the likely issue from the five potential problems listed above.

Remember, most clogging issues can be resolved with minor adjustments, particularly in grind size or pouring technique. With patience and practice, you can continue to enjoy your V60 brew without unnecessary disruptions.
