Master V60 grind size with this complete guide. Learn the exact grind settings for your grinder, how to adjust based on taste, and troubleshoot common extraction issues.
The Hario V60 is unforgiving. Use the wrong grind size and you'll get either sour, underdeveloped coffee (too coarse) or bitter, over-extracted mud (too fine). The margin for error is narrow, which is why the V60 has a reputation for being "difficult."
But here's the truth: V60 grind size isn't mysterious. It's just specific. This guide will show you exactly what grind setting to use, how to recognize extraction problems by taste, and how to dial in any V60 recipe in three brews or less.
The V60 works best with grind sizes between 500-800 microns — what most people call "medium" grind. This is finer than French press (coarse), but coarser than espresso (fine).
Why this range? The V60's design features large drainage holes and spiral ribs that promote fast, even water flow. If you grind too coarse, water races through the coffee bed in under two minutes, leaving you with weak, sour extraction. If you grind too fine, the bed clogs, brew time extends past four minutes, and you get harsh bitterness.
Visual reference:
Most grinders don't label particle size in microns. They use arbitrary numbers, clicks, or words like "medium." That's where the BrewMark Grind Converter becomes essential — it translates grind settings across 55+ grinders so you can follow any recipe.
These are proven starting points for medium roast coffee on common grinders. Your final setting will depend on your beans, water, and technique, but these baselines get you 80% of the way there.
| Grinder | Recommended Setting | Notes |
|---|---|---|
| Comandante C40 | 20-24 clicks | Start at 22, adjust ±2 clicks |
| 1Zpresso JX-Pro | 22-26 clicks | Start at 24 for light roasts |
| 1Zpresso K-Plus | 4.5-5.0 | Half-click adjustments |
| Timemore C2 | 16-20 clicks | Lighter roasts need finer (16-18) |
| Hario Skerton | Setting 6-8 | Inconsistent grinder, expect variance |
| Grinder | Recommended Setting | Notes |
|---|---|---|
| Baratza Encore | 14-16 | Start at 15 for medium roasts |
| Baratza Virtuoso+ | 12-14 | Finer than Encore for same result |
| Fellow Ode Gen 2 | 3.5-4.5 | Wide sweet spot |
| Wilfa Svart | 4-5 | Danish design, V60-optimized |
| Breville Smart Grinder Pro | 18-22 | Start at 20 |
If you're using a blade grinder, pulse in 1-2 second bursts for 10-12 seconds total. Check the consistency visually — you want uniform particles the size of coarse sand. Blade grinders produce uneven grinds (boulders + fines), so V60 results will be inconsistent. Upgrade to a burr grinder when possible.
Don't guess. Use taste feedback to systematically adjust grind until you hit the sweet spot. This method works for any coffee, any roast level, any grinder.
Start with the recommended grind setting for your grinder (see table above). Use a proven recipe:
Brew normally. When you taste it, focus on three things:
If Brew 1 was sour or finished in under 2:30:
If Brew 1 was bitter or finished after 3:30:
If Brew 1 was balanced but brew time was off:
By Brew 2, you're close. Make smaller adjustments (1 click) to zero in on perfect extraction.
If Brew 2 was almost there but still slightly sour:
If Brew 2 was almost there but still slightly bitter:
If Brew 2 tasted balanced:
Most people hit the sweet spot by Brew 3. If you're still struggling after three attempts, the problem isn't grind size — it's likely water temperature, pour technique, or stale coffee.
Light roasts and dark roasts extract differently, even on the same grinder setting. Adjust your baseline accordingly.
Light roasts are denser and harder to extract. They need:
If your light roast tastes grassy, vegetal, or painfully sour, you're underextracting. Grind finer and increase water temp.
This is the baseline. Use the recommended settings from the grinder table above. Target brew time: 2:30-3:00.
Dark roasts are brittle and extract quickly. They need:
If your dark roast tastes ashy, charred, or overwhelmingly bitter, you're overextracting. Grind coarser and lower water temp.
Use this decision tree when your V60 doesn't taste right.

If your grind setting hasn't changed but brew times vary by 30+ seconds between brews, you have a consistency problem.
Fix:
Agitation (stirring, swirling, or turbulent pouring) affects extraction independently of grind size. If you use high-agitation techniques (like James Hoffmann's method with bloom swirl and final swirl), you can grind slightly coarser than standard recipes recommend.
Why? Agitation increases extraction efficiency, so you need less surface area (coarser grind) to achieve the same extraction level.
Rule of thumb:
1. BrewMark Grind Converter
The Grind Converter translates grind settings across 55+ grinders. If a recipe says "Comandante 22 clicks" but you have a Baratza Encore, the converter tells you that's equivalent to setting 15 on your grinder.
2. BrewMark Brew Calculator
The Brew Calculator does the ratio math for you. Enter your desired dose (e.g., 18g coffee) and it calculates water needed for any ratio (1:15, 1:16, 1:17). No mental math required.
3. A notebook (or BrewMark app)
Track every brew. Write down:
After 5-10 brews, patterns emerge. You'll see that your Baratza Encore setting 15 works perfectly for medium roasts, but light roasts need 14. That knowledge compounds over time.
Most home brewers blame the beans when their V60 tastes bad. "This coffee is too acidic" or "This roaster over-roasted it." But 90% of the time, it's not the beans. It's the grind.
A light roast from a world-class roaster will taste like lemon juice if you grind too coarse. That same coffee, ground properly, tastes like peach tea with honey. The bean didn't change. The grind did.
The V60 exposes grind mistakes more ruthlessly than other methods because of its fast flow rate and large drainage holes. French press is forgiving (long steep time compensates for grind variance). AeroPress is forgiving (pressure compensates for poor extraction). The V60 forgives nothing.
That's not a weakness. It's a feature. Once you learn to dial in grind size on a V60, you understand coffee extraction at a deeper level than most home brewers ever reach.

If you want to understand grind size across all brew methods: Read the Complete Coffee Grind Size Chart for espresso, French press, AeroPress, and more.
If you want to dial in faster: Download the BrewMark app. It tracks your brews, gives you grind adjustments based on taste feedback (powered by Marcus AI), and translates recipes to your exact grinder. Three brews to dialed in, every time.
The bottom line: V60 grind size isn't hard. It's just precise. Start at medium (600-700μm), taste your coffee, and adjust in 2-click increments based on whether it's sour (grind finer) or bitter (grind coarser). By your third brew, you'll know exactly what setting works for your grinder, your beans, and your technique.
