Pour-Over Coffee Basics: Filter Types, Grind Size, and Extraction Tips

If your pour-over coffee always turns out bitter or weak, you're not alone. Many home brewers unknowingly over-extract or under-extract their coffee, leading to unpleasant flavours. The truth is, getting a balanced cup isn’t about luck—it’s about understanding how grind size, water flow, and coffee dose work together.

The key to a good pour-over lies in using the right grind (between 1.5 and 2 on a Japanese setting), dosing 1.5 to 2.5 tablespoons per person, and controlling water flow to extract only the desirable aromatic compounds—not the bitter ones.

What Is Pour-Over Coffee? Filter Types Explained

Pour-over coffee is a filtered brewing method where hot water passes through ground coffee and a filter. There are two main types: cup-style (filter paper) and bag-style (filter cloth). The Japanese pour-over (often called “manual coffee” or “hand drip”) is the most well-known cup-style method. The Italian version uses cloth bags and is typically prepared like tea bags—this is the most recognised bag-style approach.

Why Grind Size and Dose Matter in Manual Brewing

For Japanese-style pour-over, the optimal grind size is between 1.5 and 2 on the traditional Japanese grind setting—this is slightly finer than medium. Using the correct grind helps control extraction speed and flavour balance. The coffee dose should match the number of cups:

• 1 to 2 people: 1.5 to 2 tablespoons (approx. 15–20g)
• 2 people: 3 to 3.5 tablespoons (approx. 30–35g)
• 3 people: 4.5 to 5 tablespoons (approx. 45–50g)
• 4 people: 6 to 6.5 tablespoons (approx. 60–65g)
• 5 people: 7 to 7.5 tablespoons (approx. 70–75g)

Note: One flat coffee spoon holds roughly 10 grams.

Extraction: The Science Behind Coffee Flavour

Coffee contains both pleasant aromatic compounds and undesirable bitter, astringent ones. If your coffee tastes bitter even though the beans aren’t dark roasted, you’ve likely extracted too much of the wrong stuff. Extraction refers to how much of the coffee’s contents dissolve in water. Extraction rate measures the proportion of those aromatic compounds that make it into your cup.

Think of brewing coffee like steeping tea. The first brew often tastes the best because the sweet, soluble flavours come out first. Over-steeping draws out tannins and bitterness. Coffee works the same way: aim to extract the good flavours without overdoing it. Unlike tea, coffee grounds can only be brewed once—if you over-extract, you get bitterness and dryness, not just dullness. With espresso, the crema offers visual clues to problems, but in pour-over, you have to rely entirely on technique.

How to Control Your Pour-Over for the Best Results

Manual brewing success depends on precision. The goal is to pull out the desirable flavour compounds while leaving behind the harsh or burnt-tasting ones. Here’s how:

• Use the correct grind size (1.5–2 on Japanese scale).
• Dose the right amount of coffee per person (see table above).
• Control your water flow: pour slowly, steadily, and evenly.
• Don’t over- or under-brew—balance is everything.

When done right, your pour-over will express a full range of flavours: sweetness, acidity, bitterness, body, and aroma. But it takes practice—most experts say it takes 5 to 10 years to master the subtle water control and timing needed for a truly great cup.

Frequently Asked Questions

What is the ideal grind size for pour-over coffee?

The recommended grind size for Japanese-style pour-over coffee is between 1.5 and 2 on the traditional Japanese grind scale—this is a slightly finer than medium setting. This grind size helps achieve proper extraction without over- or under-extracting the coffee.

How much coffee should I use per cup?

For pour-over coffee, use 1.5 to 2 tablespoons (about 15–20g) for one to two people, scaling up to 6 to 6.5 tablespoons (60–65g) for four people, or 7 to 7.5 tablespoons (70–75g) for five. One flat coffee spoon holds around 10 grams.

What causes bitterness in pour-over coffee?

Bitterness usually results from over-extraction, where the water pulls out undesirable bitter and astringent compounds from the coffee grounds. Even light or medium-roast beans can taste bitter if brewed too long or with too fine a grind.

Does pour-over coffee taste better than regular drip?

Pour-over coffee often tastes cleaner and more vibrant than standard drip because it gives the brewer control over water temperature, flow rate, and contact time. This allows for better extraction of aromatics and a more balanced cup.

How long does it take to learn to brew great pour-over coffee?

According to the article, it can take 5 to 10 years of practice to master manual pour-over brewing. Achieving the right water control, timing, and consistency is a skill that develops over time with experience.

What’s the difference between filter paper and filter cloth in pour-over?

Filter paper is used in cup-style pour-over (like Japanese hand drip), while filter cloth is used in bag-style brewing (like Italian drip bags). Cup-style is the most well-known manual method, while bag-style resembles tea brewing and is less common.
