Why we use these ratios?

Espresso Ratios

Espresso is a highly concentrated brew, requiring a fine grind and precise water pressure. A low-strength espresso with a 1:3 ratio produces a lighter, more diluted shot suited for beginners or those who prefer a milder taste. At the other end, a 1:1.5 ratio results in a rich, intense shot ideal for those who enjoy strong espresso. Ratios from 1:2 to 1:1.5 create a balanced shot with complex flavors and a creamy texture, often preferred for drinks like lattes and cappuccinos.

Pour-Over Ratios (V60, Kalita, etc.)

Pour-over methods such as the Hario V60 and Chemex are designed to create a clean, balanced cup that highlights clarity. Using a medium to coarse grind, a 1:17 ratio yields a lighter, more floral brew, while a 1:14 ratio produces a richer, fuller-bodied coffee. Adjustments in extraction time and water flow help refine the flavors, enhancing or balancing the coffee’s unique characteristics.

Auto Drip Ratios

Auto drip machines provide a steady pour of hot water over coffee grounds, yielding consistency but with limited customization. A 1:18 ratio delivers a delicate profile suitable for light roasts, while a 1:15 ratio results in a richer, bolder flavor. These ratios work well across roast levels, helping achieve a balanced cup.

French Press Ratios

The immersion method used in French press brewing involves steeping coffee grounds in hot water for several minutes. A 1:15 ratio offers a smoother, more subtle profile, while a 1:12 ratio enhances the boldness and body. Since the French press retains oils and fine particles, these ratios balance the rich flavors without risking over-extraction.

Cold Brew Ratios (Concentrate)

Cold brew, made with a coarse grind and extended steeping time, provides a smooth, low-acid profile. A 1:5 ratio creates a concentrate that can be diluted to taste, retaining complexity even when mixed.

Cold Brew Ratios (Ready-to-Drink)

For a ready-to-drink cold brew, a lighter 1:10 ratio produces a refreshing, subtle coffee with no need for dilution.

Chemex Ratios

The Chemex, with its thick filter, highlights clarity and brightness in coffee. Ratios of 1:17 to 1:14 work well, where a 1:17 ratio brings out subtle, delicate notes, while a 1:14 ratio emphasizes body without sacrificing clarity.

AeroPress Ratios

With its versatility, the AeroPress allows experimentation with ratios from 1:13 to 1:16. A 1:13 ratio gives a strong, espresso-like flavor, while a 1:16 ratio results in a lighter, more tea-like body, offering a range of options for AeroPress fans.

Moka Pot Ratios

The Moka pot produces a strong, espresso-like coffee. A 1:11 ratio balances flavor, while a 1:8 ratio intensifies concentration. This stovetop method uses steam pressure for extraction, so ratios are chosen to manage both strength and taste.

Turkish Coffee Ratios

With its unfiltered, rich profile, Turkish coffee is made by leaving the grounds in the cup. A 1:9 ratio produces a deep, traditional flavor, while a 1:12 ratio results in a lighter yet still rich drink.

Siphon Ratios

The siphon brewer uses water vapor pressure to create a rich, aromatic coffee. Ratios from 1:16 to 1:13 work well; a 1:16 ratio highlights brightness and floral notes, while a 1:13 ratio offers a concentrated, rich cup. These values support balanced extraction while emphasizing the unique aromatic qualities of siphon brewing.
