How Fine Should You Grind Coffee for the Perfect Pour Over?
When it comes to brewing the perfect cup of coffee, every detail matters — from the quality of the beans to the water temperature, and crucially, the grind size. For pour over coffee enthusiasts, understanding how fine to grind coffee is a key step that can dramatically influence the flavor, extraction, and overall experience. Getting this just right unlocks the full potential of your beans, ensuring a balanced, aromatic, and satisfying brew.
Grinding coffee for pour over is a delicate balance. Too coarse, and the water will flow through too quickly, resulting in a weak, under-extracted cup. Too fine, and the brew can become bitter or overly intense due to over-extraction. The grind size acts as a gatekeeper, controlling the extraction rate and ultimately shaping the taste profile of your coffee. It’s an art and a science that every pour over lover should explore to elevate their daily ritual.
In the following sections, we’ll delve into the nuances of grind size specifically for pour over methods, exploring how different grind levels affect brewing time, flavor clarity, and overall cup quality. Whether you’re a beginner or looking to refine your technique, understanding how fine to grind your coffee will help you craft a consistently delicious pour over every time.
Optimal Grind Size for Pour Over Coffee
Achieving the perfect grind size for pour over brewing is essential to extracting balanced flavors and aromas from your coffee beans. The grind size should be medium to medium-fine, resembling the texture of granulated sugar. This allows the water to flow through the coffee bed at an ideal rate, avoiding under-extraction or over-extraction.
When the grind is too coarse, water passes through too quickly, resulting in a weak and sour cup due to under-extraction. Conversely, a grind that is too fine slows water flow excessively, leading to bitterness and astringency caused by over-extraction. Adjusting grind size is therefore critical to controlling extraction time and flavor balance.
Factors Influencing Grind Size Choice
Several variables affect the ideal grind size for your pour over setup:
- Brewing Time: A typical pour over brew time ranges between 2.5 to 4 minutes. If your brew finishes too quickly, a finer grind is necessary; if it takes too long, coarsen the grind.
- Filter Type: Different filters (e.g., paper, metal) affect flow rate. Paper filters usually require a slightly finer grind than metal filters.
- Coffee Bean Roast Level: Darker roasts tend to require a coarser grind due to their more brittle structure, while lighter roasts benefit from a finer grind to enhance extraction.
- Water Temperature and Pour Technique: Higher water temperature and controlled pouring can impact extraction and may necessitate minor grind size adjustments.
Guidelines for Adjusting Grind Size
To dial in your grind size for pour over coffee, consider these practical tips:
- Start with a medium grind similar to table salt.
- Observe extraction time; aim for 3 to 3.5 minutes total brew time.
- Taste the coffee for balance; if it tastes sour or weak, grind finer; if bitter or harsh, grind coarser.
- Make incremental grind adjustments; changing the grind by too much can drastically alter brew quality.
- Keep other variables constant (water temperature, coffee dose, pouring method) when adjusting grind size.

Optimal Grind Size for Pour Over Coffee
The grind size for pour over coffee plays a critical role in extraction quality, impacting flavor clarity, acidity, and body. Achieving the ideal grind ensures balanced extraction, avoiding over-extraction (bitterness) or under-extraction (sourness or weak flavor).
Pour over brewing typically requires a medium-fine grind, which is slightly finer than drip coffee but coarser than espresso. This grind size provides the optimal surface area for water to interact with coffee grounds during the relatively short brew time and moderate flow rate.
Characteristics of a Medium-Fine Grind
- Texture: Resembles granulated sugar or slightly finer table salt.
- Particle Size Range: Approximately 500–700 microns in diameter.
- Appearance: Particles should be uniform with minimal fines (very small particles) to avoid excessive extraction.
- Flow Rate: Allows water to pass through the coffee bed steadily, typically 2.5 to 4 minutes brew time.
Grind Size Comparison Table
| Grind Type | Typical Particle Size (Microns) | Common Brewing Method | Flow & Extraction Characteristics |
|---|---|---|---|
| Coarse | 1000–1200 | French Press, Cold Brew | Slow extraction, longer brew time, rough texture |
| Medium-Coarse | 800–1000 | Chemex, Clever Dripper | Moderate extraction, balanced flow rate |
| Medium-Fine | 500–700 | Pour Over (V60, Kalita Wave, etc.) | Optimal flow, balanced extraction, clear flavors |
| Fine | 300–500 | Espresso | Fast extraction under pressure, intense flavor |
