The Dragon Boat Festival is a time for family gatherings and savoring traditional sticky rice dumplings. Whether it’s the Southern-style with its rich, savory braised flavor and soft, moist texture, or the Northern-style with its aromatic oiliness and chewy rice, it’s easy to indulge in one after another. But after a few dumplings, the heaviness can start to weigh on your palate. That’s when a refreshing iced coffee comes to the rescue—reviving your senses and offering a delightful contrast.
In this article, we present three summer-perfect iced coffee styles—Cold Brew, Japanese Iced Pour Over, and Sparkling Coffee. Whether you prefer something mellow, vibrant, or playful, these coffees make the perfect companions for refreshing during this season.
❄️Cold Brew Coffee: Mellow Charm of Low-Temperature Extraction
Cold Brew is made by steeping coffee grounds in cold water over an extended period, without applying heat. This method preserves the coffee’s natural sweetness and smooth mouthfeel, while avoiding the sharp bitterness that hot brewing can bring. The result is a mellow, rounded flavor profile with chocolatey and nutty notes—ideal for slowly sipping on a hot afternoon.
How to make it:
Mix coffee grounds and cold water in a 1:15 ratio. Refrigerate for 12 to 24 hours, then filter. For a stronger brew (e.g. 1:8), you can blend it with oat milk or sparkling water to create a unique signature drink.
Recommended bean types:
Medium to medium-dark roasts such as Colombian, Guatemalan, Brazilian, or Sumatran beans. Natural or honey-processed beans also work well, offering a rich sweetness and full body.
Justin Coffee Recommends: Kenya Kiambu Tatu Estate, Natural Process｜Light Roast
▶ Flavor: Red cherry, fermented fruit, pineapple, rich and syrupy body
🧊 Japanese Iced Pour Over: A Burst of Aroma Instantly Sealed
Japanese Iced Coffee is the most aromatic of all iced brewing methods. Unlike Cold Brew, it uses hot water to extract coffee, which is then dripped directly onto ice. This rapid cooling technique locks in the aroma while producing a bright acidity and structured flavor profile. It’s like enjoying the depth of hot coffee, but with the added freshness and chill—perfect for summer mornings or post-meal refreshment.
How to make it:
Brew coffee using the pour-over method, but account for the total liquid volume including the ice. For example, use 180g of hot water to brew directly over 150g of ice. Drink immediately after brewing.
Recommended bean types:
Light-roast, washed beans such as Ethiopia Yirgacheffe, Costa Rica Honey Process, or Kenya—ideal for expressing floral and fruity aromas with balanced acidity.

▶ Flavor: Citrus, peach, black currant, chocolate, brown sugar, caramel, high sweetness, bright acidity, full body, long-lasting aftertaste, excellent balance
🫧 Sparkling Coffee: A Playful Burst of Cool Refreshment
Sparkling Coffee is a rising star in the coffee world. It combines coffee with sparkling water to create a soda-like, refreshing drink. Using espresso or a strong pour-over concentrate as the base, it can be mixed with sparkling water, citrus zest, orange juice, syrups, or spices—offering coffee aroma with a light, soda twist. Great for cleansing the palate or cooling off in the summer heat, it’s a fun and invigorating choice.
How to make it:
Add 40g of espresso (or strong coffee) to 200g of sparkling water. Serve with ice, citrus peel, syrups, or fruit juice, mix well before drink. Use unsweetened sparkling water for a cleaner flavor.
Recommended bean types:
Uniquely processed beans like Colombian rum barrel-aged coffee or high-sweetness Ethiopian Gesha varieties showcase bright, aromatic flavors that complement the fizz.

▶ Flavor: Rum, tequila, green apple, grape, lime, raw cacao
