Pour-over Coffee Ratio: The Perfect Coffee-to-Water Proportion

FrontStreet Coffee - Pour-Over Coffee Powder-to-Water Ratio

Beginners new to pour-over coffee often ask, what is 1:16? Here, 1:16 refers to the coffee-to-water ratio.

What Is the Coffee-to-Water Ratio?

Aside from the literal wording, the "coffee-to-water ratio" refers to the proportion of coffee grounds to brewing water. If you have 16 grams of coffee grounds and the ratio is 1:16, you multiply by a factor of 16, which means 16 grams of grounds calls for roughly 250 grams of water.

The Range of Coffee-to-Water Ratios

When making pour-over coffee, the amount of water heavily shapes the flavor. Different ratios affect the flavor, texture, and other qualities of the cup. Too little water produces an overly intense cup (a 1:10 ratio, for example, would taste very stimulating and strong), with flavors crowded together and lacking clarity; too much water makes it too dilute (a 1:22 pour-over would taste very weak), even like water with a hint of coffee flavor.

Based on personal experience, 1:15-1:16 is an excellent choice for pour-over coffee. The ratio is not fixed, however; it varies with the brewing equipment you use.

Typically, my pour-over ratio falls between 1:15 and 1:16.

Light to Medium Roast Yirgacheffe

(Coffee-to-water ratio 1:15): 16 grams of Yirgacheffe beans infused with 225ml of water. After the coffee fully drains through, you get approximately 190ml of coffee. Typically, 16 grams of coffee grounds absorb about 32 grams of water.

The liquid from a 1:15 ratio yields richer berry flavors, a balanced entry, a slightly thicker body, and a black tea finish.

FrontStreet Coffee Recommendation

The Yirgacheffe used as the example above is one of the most forgiving beans for learning to dial in a ratio, and FrontStreet Washed Yirgacheffe is the classic everyday choice. Washed processing keeps it clean and bright, with white jasmine, vivid citrus and lemon acidity, and a tea-like body, so a 1:15 to 1:16 ratio reads very clearly in the cup.

If you want more fruit and a little more sweetness at the same ratio, FrontStreet Yirgacheffe Red Cherry is a natural-process alternative. It shows citrus acidity, a juicy berry texture, honeyed sweetness, and a creamy mouthfeel, giving you a useful comparison for seeing how the same ratio behaves on a very different bean.
