How to Make Doutor Coffee: 3 Japanese Iced Coffee Recipes

If you’ve ever walked past a Doutor coffee shop in Japan—or seen photos of its iconic pink-and-white interiors—you might have wondered: how exactly do they make those eye-catching iced coffee drinks? Known for cheap, high-quality coffee at just ¥150 a cup, Doutor serves up crowd-pleasing iced blends with simple techniques and striking presentation. Here’s how to recreate three of their most popular iced coffee drinks at home, with exact measurements and steps.

Doutor’s three standout iced coffee recipes—Rainbow Ice Coffee, Latin Ice Coffee, and Eden Ice Coffee—can be made with 120ml of pre-brewed iced coffee each. Key ingredients include flavored syrups, fresh cream, alcohol (like green mint or brandy), crushed ice, and toppings such as strawberries, cotton candy, or chocolate. Below, we break down each recipe step-by-step with exact ratios.

Frequently Asked Questions

Can I use regular brewed coffee instead of iced coffee for these recipes?

Yes, but you must chill it completely before mixing. Doutor’s recipes call for 120ml of “iced coffee,” meaning coffee that’s already cold—either pre-brewed and refrigerated or brewed double-strength then cooled. Using hot coffee will melt the ice too quickly and dilute the flavors.

What can I substitute for green mint liqueur in the Latin and Eden recipes?

If you prefer a non-alcoholic version, you can skip the green mint liqueur or replace it with a mint syrup. Keep in mind the alcohol adds both flavor and a slight kick, so the taste will change if omitted.

Is the honey in Rainbow Ice Coffee essential, or can I use sugar syrup?

The original recipe uses 15ml of honey. You could substitute it with an equal amount of sugar syrup, though the flavor will be slightly less floral and more neutral. Honey gives the drink a distinct taste that complements the strawberry and pomegranate.

Do I need to use specific brands for the liqueurs or cream?

No, any standard green mint liqueur, brandy, or fresh cream will work. Doutor uses basic commercial versions for consistency and cost, so feel free to use what’s available locally.

Can I make these drinks ahead of time?

It’s best to assemble them just before serving. Crushed ice melts quickly, and toppings like fresh cream or marshmallows will start to dissolve or soften, affecting texture and appearance.
