“Even living a few states away and the coffee being shipped to our home was a good experience.”

What customers say

I ordered their House Blend and Bali Moon grounded coffee and was pleasantly surprised by the complex aroma and smooth blend. Shipping was on time as expected. And their website is easy to navigate as well. I recommend Ruang Kopi for their authentic Indonesian coffee blend.

Fantastic coffee! Even living a few states away and the coffee being shipped to our home was a good experience. I found the Timor-Leste was best brewed in a Chemex, which made for a fruitier taste. The cider tasting notes were spot on as it a was less acidic but still sweet.
