When it comes to classic summer drinks, iced coffee is a must. With its crisp bitterness and clean aftertaste, it's perfect for waking up in the morning or for a refreshing drink.
However, many people may wonder, "How do I choose beans for iced coffee?" and "Am I allowed to use the same beans as for hot coffee?"

To help you enjoy this perfect hot-weather drink even more, this article will clearly explain the roast level, how to choose beans, and brewing methods that are ideal for iced coffee.
Please use this as a reference to find your favorite cup.

What is the best roast level for iced coffee?

Since iced coffee is drunk cold, the aroma and sweetness are less noticeable than with hot coffee.
Therefore,
medium-dark to dark roasted beans with a strong body and bitterness are particularly suitable .

Medium roasts tend to have a strong acidity, which can be unbalanced when cooled. On the other hand, dark roasted beans do not lose their flavor when cooled, and their flavor lasts even when diluted with ice.

These beans have a refined bitterness and a chocolate-like sweetness. By roasting them medium-dark to dark, you can enjoy their rich aroma and deep flavor even when chilled.

The combination of grinding and brewing method is also important

To get the most out of the beans, it is important to combine the grinding and brewing methods appropriately .

Rapid cooling method (drip + ice) : Medium-fine grind
→ A strong drip brew and then quickly cooled with ice. This style brings out the individuality of the beans and retains their aroma well.

Cold brew coffee : Medium coarse grind
→ By extracting slowly over time, the bitterness is reduced, resulting in a mellow, easy-to-drink coffee. It pairs well with dark roasted beans.
