Rangga Saputro is best known as the barista at Kafe Olivier who brewed the iced Vietnamese coffee consumed by Wayan Mirna Salihin on January 6, 2016. During the high-profile murder trial and the Netflix documentary Ice Cold: Murder, Coffee and Jessica Wongso (2023), Rangga was thrust into the spotlight when rumors and unproven claims linked him to the incident—including false allegations that he received money to harm Mirna.
