Pour-Over Coffee Ratios: Practical Parameters & How Many Beans Per Cup

Pour-over has captivated coffee lovers worldwide, and it has become one of the most popular extraction methods for exploring coffee aromatics. Almost every coffee enthusiast keeps a set of pour-over gear at home. In a quiet moment they will pick a favorite bean, brew a pot, weigh the beans, grind, fold the filter paper, rinse the dripper, add the grounds, pour in circles, taste — every step carrying its own sense of ritual.

But for those who brew often, do you know where this drip method came from? This article walks through the story and the practice of pour-over coffee.

Who Invented Pour-Over Coffee?

For a long stretch of history, people brewed coffee in a simple, crude way: grind the beans, boil them in a pot, strain out the residue with burlap or metal mesh, and drink. Because the manufacturing technology of the time could not produce mesh with fine enough pores, the filtered coffee usually still carried quite a lot of sediment.

All of that changed thanks to a German woman who loved freshly brewed coffee. Amalie Auguste Melitta Bentz found coffee made with traditional filters bitter, and grounds kept getting stuck between her teeth, ruining the mouthfeel. So she kept experimenting, determined to solve the filtration problem, until she landed on an idea:

She punched holes in the bottom of a copper pot to make a sieve-like container, laid a piece of blotting paper on top, added ground coffee, and poured hot water over it — letting the coffee drip through the paper into the pot below. Compared with burlap or metal mesh, Melitta's design filtered out the residue while preserving the coffee's aroma. It was inexpensive, simple, and convenient, and above all it produced a clean, sediment-free cup that tasted dramatically better.

What is Pour-Over Coffee?

The coffee beans we buy have been roasted at high temperature, setting off a chain of chemical reactions that generates all sorts of aromatic compounds. Brewing is simply the act of using water and equipment to release those flavor compounds. In pour-over coffee, we first grind the beans into powder, then pour hot water over the coffee bed to "dissolve" those substances out. Essentially, a dripper fitted with filter paper traps the grounds so they never reach the pot below, yielding a clean-tasting black coffee.

Keep in mind that from bean selection to extraction, every step affects the final flavor to some degree. To brew pour-over at home, FrontStreet Coffee's experience says that beyond good beans you need at least the following: a gooseneck kettle for controlled pouring, a dripper and filter paper, a serving pot, a grinder, an electronic scale to track water volume and time, and a thermometer for water temperature.

Of course, great coffee starts with great ingredients. FrontStreet Coffee recommends choosing beans within 4-30 days of roasting — their optimal flavor window — which favors stable extraction and fuller flavors in the cup. To guarantee freshness, FrontStreet Coffee ships beans roasted within 5 days, typically arriving within 1-3 days, so the beans you receive are still inside their peak window and ready for you to experiment with.

How to Brew a Cup of Coffee at Home?

From years of brewing experience, FrontStreet Coffee advises beginners to start with a three-stage pour. Three-stage extraction dissolves flavor compounds more fully, builds layers of taste, and avoids the over-extraction that prolonged soaking can cause.

For 15 grams of coffee at a 1:15 coffee-to-water ratio — 225ml total water — the three pours break down as 30ml, 95ml, and 100ml, with the scale reading 30g, 125g, and 225g at each stop.

Here FrontStreet Coffee brews its own house-roasted washed Yirgacheffe Gedeb Cooperative beans in an Hario V60. The V60's spiral ribs let the grounds degas thoroughly, maximizing the release of acidic aromatics. Because Yirgacheffe is roasted light and the beans are correspondingly hard, they need high-temperature water at 92°C-93°C to draw out the floral and fruity notes.

FrontStreet Coffee recommends a medium-fine grind — a 78% pass rate through the #20 sieve — roughly the texture of fine sugar. Grind too coarse and you cannot extract the mellow, rounded flavor compounds, leaving a thin, watery cup; grind too fine and the high water temperature will push you into over-extraction and bitterness.

On ratios, FrontStreet Coffee considers both 1:15 and 1:16 perfectly workable. Want a richer taste? Use 1:15. Want the florals and sweetness to stand out more clearly? Use 1:16 and let the flavors open up.

First, seat the folded filter paper in the dripper, add the 15 grams of ground coffee, and zero the scale.

For the first stage, pour 30g of water and bloom for 30 seconds. Start the timer as you pour, using a small stream spiraling outward from the center so the entire coffee bed is wetted.

After 30 seconds, begin the second stage: 95g of water with a slightly larger, steady stream, aiming to lift and saturate the whole coffee bed. Keep the water column vertical and even. The scale should read 125g, and this pour should finish around 55 seconds.

Once the liquid level drops to half, use a small stream to pour the final 100g in tight circles. Keep the flow gentle — a heavy hand scatters the coffee bed and causes under-extraction. Total water comes to 225g, with drawdown finishing around 2 minutes. Remove the dripper, swirl the coffee in the serving pot to even it out, and taste.

The water for each stage is not set in stone. Adjust it based on your own experience and your understanding of each coffee. FrontStreet Coffee believes there are a thousand ways to brew a delicious cup — study more, practice more, and mastering pour-over parameters is not difficult.

FrontStreet Coffee Recommendation

The washed Yirgacheffe Gedeb used in this guide is the perfect first step into pour-over: it opens with vivid citrus, berry, and floral notes and finishes with a green-tea-like sweetness, its acidity soft and bright rather than sharp. If you prefer something fruitier, FrontStreet Ethiopia Natural Huakui delivers striking tropical aromatics — strawberry, passion fruit, jackfruit, even lychee — with obvious sweetness, almost no bitterness, and a smooth, juice-filled mouthfeel that wins over people who think they dislike coffee. Both shine in a V60, whose fast extraction renders floral, fruity, and tea-like characters in full relief. The V60 itself, redesigned by Hario in 2004 around its signature 60-degree cone, rewards a steady hand with remarkably layered aroma and lively acidity — exactly the qualities that make light-roast Ethiopia so rewarding to brew.
