Picture this: It's a scorching summer afternoon, and you crave a refreshing, smooth, and bold cold brew coffee that delivers the perfect balance of flavour and strength. But how do you achieve that barista-quality taste at home? The secret lies in getting the cold brew ratio just right.
Unlike hot coffee, where the brewing process is quick and extracts flavours rapidly, cold brew requires patience and precision. Whether you prefer a strong, concentrated brew or a lighter, ready-to-drink version, mastering the ideal coffee-to-water ratio is key. In this guide, we'll explore the best cold brew ratios, how they impact flavour, and tips for crafting your perfect cup every time.
What is Cold Brew Coffee?
Cold brew coffee is made by steeping coarse-ground coffee in cold or room-temperature water for an extended period, usually 12–24 hours. This slow extraction process reduces acidity, enhances sweetness, and produces a smooth, bold coffee concentrate that can be enjoyed black, with milk, or diluted with water.
Why Cold Brew is Different from Iced Coffee
Many people confuse cold brew with iced coffee, but they are fundamentally different:
- Cold Brew is steeped for hours, resulting in a low-acid, naturally sweet coffee.
- Iced Coffee is brewed hot and then chilled, often resulting in a more acidic and bitter taste.
Cold brew’s smooth and rich profile makes it a favourite among coffee enthusiasts looking for a less acidic and highly caffeinated drink.
Cold Brew Coffee Ratios Explained
The cold brew ratio determines how strong or mild your coffee will be. The general rule is: the more coffee you use relative to water, the stronger the concentrate.
Common Cold Brew Ratios:
- 1:4 Ratio (Strong Concentrate) – Perfect for those who like their coffee bold and intense. Needs to be diluted before drinking.
- 1:6 Ratio (Balanced Concentrate) – A versatile option that offers strength with a smooth taste. Ideal for mixing with milk or water.
- 1:8 Ratio (Ready-to-Drink) – No dilution needed. This is a great option if you enjoy a milder, more refreshing cold brew.
Understanding Concentrate vs. Ready-to-Drink Cold Brew
- Cold Brew Concentrate (1:4 or 1:6 Ratio): Must be diluted with water, milk, or a milk alternative before drinking.
- Ready-to-Drink Cold Brew (1:8 Ratio or higher): Brewed to be consumed as is, without dilution.
Choosing the right ratio depends on how you like to enjoy your cold brew—whether as a strong shot, with milk, or straight over ice.

Strong Concentrate (1:4)
- Bold, intense, and rich
