Introduction:Iced pour over coffee has gained increasing popularity in recent years, but many people wonder why it is usually more expensive than hot pour over and why it requires more coffee grounds. In fact, the key lies in the dilution effect of ice and differences in brewing methods. This article delves into the core principles of iced pour over, including adjustments to coffee dosage, brew ratio settings, the impact of different types of ice on flavor, and offers practical advice along with bean selection tips to help you brew a cup that is rich yet well-balanced.

Many pour over enthusiasts have encountered a common question when ordering iced pour over: why is it often more expensive than hot pour over? Some assume it’s because the preparation process is more complicated, but the main reason is actually the typically higher amount of coffee grounds used. So, how much coffee should you use for iced pour over? And why is there such a big difference in brewing techniques compared to hot pour over?

To understand the coffee dosage and parameter settings for iced pour over, we first need to discuss the impact of ice on the brewed coffee. When we use ice as a cooling medium, the melting process dilutes the coffee liquid. This means we can’t rely solely on a large volume of hot water to fully extract the flavor compounds from the coffee, as we might with hot pour over. Therefore, iced pour over usually employs a higher brew ratio to produce a more concentrated coffee liquid. This way, even after the ice melts, the coffee can still maintain good flavor expression and a rich mouthfeel.

For example, using 15 grams of coffee grounds as a baseline, a common hot pour over brew ratio is 1:15, meaning 225 milliliters of hot water are poured. In contrast, iced pour over raises the brew ratio to 1:10, using only about 150 milliliters of hot water, along with approximately 100 grams of ice. As a result, although the initial brewed coffee volume is smaller, the overall concentration is higher. This allows it to achieve a balanced flavor and body once the ice gradually melts, with the final cup size around 200 milliliters — ideal for single servings.

However, the aforementioned brew ratio is not set in stone.In reality, it varies depending on the type of ice used. If you’re using large, solid ice cubes that melt slowly, a smaller brew ratio (such as 1:10 or 1:11) can still preserve the flavors without significant loss. But if your ice is smaller and melts faster, you may need to adjust to a higher brew ratio, such as 1:7 or 1:8, to prevent the coffee from becoming too diluted and tasting weak too quickly.

However, increasing the brew ratio also means the final volume of coffee liquid may be reduced, which could leave some customers with an empty cup before they’ve finished drinking. Therefore, some shops choose to add more coffee grounds to both maintain the coffee liquid volume and further enhance the richness and complexity of the overall flavor. Interestingly, adding just a few extra grams of coffee can sometimes not only compensate for the reduced volume but also bring out more aromatic complexity and texture, elevating the overall quality of the iced pour over.

If you’d like to experiment with different effects yourself, try keeping other variables—such as brew ratio and water temperature—constant, then gradually increase the coffee dosage by 2–3 grams and observe how the flavor and mouthfeel change. This kind of experiment can help you more intuitively understand how coffee dosage impacts the brewing results.

As for which coffee beans are best for iced pour over, theoretically any beans can be used, but if you want to highlight clear floral and fruity notes or bright acidity, single-origin beans are a better choice. For instance, if you prefer refreshing floral aromas and vibrant acidity, you can opt for beans with citrus or berry profiles. If you enjoy intense juice-like flavors or sweetness, go for beans with prominent fermentation characteristics. And if you lean toward a mellow, low-acidity profile, dark-roasted Indonesian beans like Golden Mandheling are also a great option.

No matter which beans you choose, it’s recommended to adjust the brew ratio and brewing strategy based on your preferred flavor profile, so you can truly brew an iced pour over that suits your taste. Through continuous experimentation and fine-tuning, you’ll gain a deeper understanding of the nuances of iced pour over and enjoy a cool, rich cup during the summer months.
