Watermelon-fermented filter coffee at Daeheung café Ieo Coffee

In short

Ieo Coffee Roasters Gongdeok Branch is a roastery café tucked in an alley between Daeheung Station and Gongdeok Station in Mapo, Seoul. The writer paired an iced Colombia Via Clara Watermelon filter coffee with an egg financier (₩4,900), finding black tea aroma flowing into ripe watermelon sweetness with no artificial edge. A strong pick for specialty coffee before or after a walk along the Gyeongui Line Forest Trail.

Getting there: Come out Exit 3 of Daeheung Station and go straight; once you spot the S-oil gas station, it's hiding in the small alley right behind it! It felt like finding my own secret hideout, so my heart was already racing as I stepped into the alley haha.

Table seating good for conversation

There's plenty of bar seating where you can quietly watch the coffee being brewed if you're solo, plus quite a few table seats good for chatting with friends. The space isn't huge, but it's laid out so well that it's a comfortable Daeheung Station café.

Being a roastery café, the coffee lineup here is really impressive! The filter coffee selection especially is so good that I knew I had to try one haha.

On top of drinks, there's a decent variety of desserts too, like cookies and cakes, that go well alongside.

Here's our pick!

  • Colombia Via Clara Watermelon (iced)
  • Egg financier (₩4,900)

Colombia Via Clara Watermelon 🍉

Isn't the name itself intriguing? Apparently real watermelon is added during the anaerobic fermentation of the green beans, giving it a special process. The description said it has notes of watermelon, black tea, and lemon zest, so I was half-skeptical as I tried it iced and cold... and wow, this is seriously incredible.

Iced Colombia Via Clara Watermelon filter coffee

The moment I took a sip, a gentle, fragrant black tea aroma spread out, and right at the finish, the sweet juiciness of a perfectly ripe watermelon hit me! It wasn't artificial syrupy sweetness at all — it was genuinely pleasant fruit acidity and sweetness, so it was fascinating and delicious. Completely my type!!

Egg financier

You can't skip a sweet dessert, so we also ordered the egg financier (₩4,900)! Chewy on the outside, soft and moist inside — pure honey-flavored bliss.

Its subtle sweetness and nuttiness paired amazingly with the bright, acidic filter coffee. One sip of coffee, one bite of financier — that's heaven right there haha. Both together were the best combo!!

Final verdict

It was 200% worth having this place saved on my map for so long! You get to taste high-quality specialty coffee brewed by a barista who's truly passionate about coffee, and the space itself is so pretty that I got a proper dose of healing haha.

It's the perfect location to grab a delicious coffee to-go and walk right into the Gyeongui Line Forest Trail out front, so if you're looking for a Gyeongui Line Forest Trail café or a nice-vibe Gongdeok café or Daeheung café, I strongly recommend visiting Ieo Coffee Roasters~~!! ><
