Teh Botol Sosro has been a market leader in bottled tea in Indonesia since 1940. It introduced bottled tea and saw success through sampling promotions. In 1974, PT Sinar Sosro was established to produce Teh Botol Sosro. While it remains popular due to flavor and quality, a marketing strategy is being developed to reposition its image and packaging for the modern market through a bottle redesign and promotional campaign.
