Hidden light within every bean. Obsira was born from the pursuit of balance — between science and soul, precision and intuition, light and shadow. Founded by Jason Darien Riadi, an aerospace engineer turned coffee roaster, German Brewers Cup 3rd Place winner 2024 and SCA Germany juror, Obsira began as a quiet experiment: to see if the same principles that govern aerodynamics could also shape the sensory world of coffee. Here, roasting isn't just a process — it's observation. Every batch is guided by data, refined by taste, and finished with patience.
