Comandante MK4 Settings: How to Dial in Perfect Grind Size for Pour-Over Coffee

The Comandante MK4 grinder is a benchmark in the world of manual coffee grinding. Its precise, step-less adjustment system allows you to dial in grind sizes from espresso to French press with remarkable consistency. But for many home baristas, understanding the click system and finding the perfect grind size for pour-over can be intimidating. In this guide, we'll break down Comandante MK4 settings, share recommended click ranges for popular brew methods, and offer practical tips to achieve a consistent grind every time.

Whether you're brewing a delicate single-origin like Corazón de Jesús or a bold natural-processed La Colina Natural, the right grind size unlocks the full potential of your coffee. With the Comandante MK4, you have the control to match the grind to your brew recipe. Let's dive into the details so you can grind with confidence.

Understanding the Comandante MK4 Click System

The Comandante MK4 features 40 clicks per full rotation of the adjustment dial, with each click representing a precise change in burr distance. The total grind range spans about 20 full rotations (800 clicks), from zero (burrs touching) to the coarsest setting. This system allows extremely fine control—a single click can make a noticeable difference in extraction. The MK4 also includes a red dot indicator and a numbered dial for easy reference. To zero the grinder, tighten the dial until you hear the first light chirp of burrs touching, then back off one click to the zero position.

Many users benefit from the optional Red Clix upgrade, which doubles the number of clicks per rotation to 80, offering even finer adjustment. This is especially useful for espresso, but for pour-over, the standard 40-click system provides ample precision. When starting, it's helpful to know that pour-over grind sizes typically fall between 20 and 30 clicks from zero. For example, a V60 often works well around 22–25 clicks, while a Kalita Wave may require a slightly finer 20–23 clicks.

• Zero your grinder: tighten until burrs chirp, then back off one click.
• Pour-over range: 20–30 clicks from zero (adjust based on brew time and taste).
• Red Clix upgrade doubles click density for espresso-level precision.

Recommended Grind Sizes for Different Brew Methods

Because the Comandante MK4 is a manual grinder, you have full control over particle distribution. Here are typical click ranges for common pour-over brewers. For the Hario V60, a medium-fine grind between 22 and 26 clicks produces an optimal extraction with a drawdown time of 2:30–3:00 minutes. Coarser settings (27–30 clicks) work for larger batches or longer steep times. For flat-bottom drippers like the Kalita Wave, a slightly finer grind (20–24 clicks) ensures even saturation and prevents channelling. Always adjust by 1–2 clicks based on taste—if coffee tastes sour (under-extracted), grind finer; if bitter or astringent, grind coarser.

For those using the Comandante with an espresso machine, the range is much finer, typically 10–15 clicks for most beans. However, this guide focuses on pour-over, where the Mk4 truly shines. Pairing your grinder with high-quality coffee beans such as EARTH COFFEE or VANESSA MORENO will reward you with bright acidity and clear flavours. Remember that different coffees may require slight adjustments even within the same method. Keep a brew log to track your settings.

• Hario V60: 22–26 clicks (medium-fine).
• Kalita Wave: 20–24 clicks (fine-medium).
• Always reference the specific coffee's roast date and origin for fine-tuning.

Step-by-Step Guide to Adjusting Grind Size

Start by ensuring your Comandante MK4 is clean and assembled correctly. Place the grinder on a stable surface, remove the catch cup, and turn the adjustment dial to your target click number (e.g., 23 clicks from zero). It's easiest to rotate the dial clockwise to decrease grind size or counter-clockwise to increase. Always count clicks carefully. For repeatability, note the click number for each coffee and brew method. After adjusting, grind a few beans to purge any residual grounds from the previous setting.

When dialling in a new coffee, use a consistent brew ratio (e.g., 60g/L) and water temperature (92–96°C). Prepare two test batches: one at your estimated click setting and one two clicks finer or coarser. Taste side by side. The Comandante's consistent particle distribution makes these small adjustments highly detectable. Over time, you'll develop a mental map of click settings for your favourite coffees. Don't forget to pair your grinder with proper paper filters such as HARIO V60 PAPER FILTER or KALITA WAVE PAPER FILTER; these also influence flow rate and extraction.

• Always purge a small amount of coffee after adjusting to clear old grounds.
• Keep a brew log with click number, coffee name, and tasting notes.
• Use a timer and scale for reproducible results.

Tips for Consistent Grinding

Consistency isn't just about the click setting—it's also about your technique. When grinding with the Comandante MK4, hold it upright and rotate the handle at a steady pace. Avoid jerky motions, which can create boulders and fines. A speed of around 2–3 revolutions per second is ideal. Also, ensure the burrs are clean; coffee oils and fines can build up and affect particle size. Disassemble and brush the burrs every few weeks, or after grinding oily beans. The MK4's burrs are made of high-alloy steel and are durable, but they should be kept dry and free of moisture.

Another tip: always grind immediately before brewing. Ground coffee loses flavour quickly, especially when fine. Use the Comandante's impressive grind uniformity to your advantage by grinding only what you need for each cup. For those new to manual grinding, consider starting with the DISCOVERY BOX from THE BARN, which includes a curated selection of single-origin coffees. This allows you to explore various origins and roast levels while fine-tuning your Comandante settings. The more you practice, the more intuitive the click system becomes.

• Steady grind speed reduces fines and improves uniformity.
• Clean burrs regularly to maintain accuracy.
• Grind just before brewing for maximum freshness.

Mastering the Comandante MK4 grinder elevates every cup of pour-over coffee. With the click system and a little practice, you'll consistently achieve the perfect grind size for any coffee. To put your new skills to use, explore the DISCOVERY BOX from THE BARN, which features a rotating selection of exceptional single-origin beans perfect for dialling in your grinder. Happy brewing!
