About the Author

Putra Siregar

Putra writes for Indonesia Specialty Coffee — origins, cupping, processing, and the trade behind every cup.

I'm a coffee enthusiast, with a deep love for Indonesian coffee, especially Sumatra coffee. I enjoy learning about and sharing the unique stories behind each cup. Exploring Indonesia's coffee culture and sharing my findings with other coffee lovers is my passion.

Through my writing, I aim to make the world of Indonesian coffee accessible to everyone. I share tips, stories, and insights about what makes Indonesian coffee special. Whether I'm talking about different regional flavors or new ways to brew coffee, I want to inspire and connect with other coffee enthusiasts.

Along with writing, I also handle coffee sales and marketing at specialtycoffee.id. With over 4 years of experience in the coffee Industry since 2021, I help our brand grow and reach more people who love coffee as much as I do.
