SOSRO is the pioneer of packaged ready-to-drink tea in Indonesia. The name SOSRO is taken from the name of the founding family, namely SOSRODJOJO. In 1940, Sosrodjojo family started their business in a small city in Central Java called Slawi. At the time, the product sold is dried tea with the brand of “Teh Cap Botol” and it was distributed only around Central Java.
In 1953, Sosrodjojo family started to expand their business to enter the capital city Jakarta to introduce “Teh Cap Botol” products that were already very popular in Central Java.
The journey to introduce the “Teh Cap Botol” product was started by doing CICIP RASA (product tasting) promotions to several markets in Jakarta. The promotion was conducted by entering the markets and brewing the “Teh Cap Botol” tea product on the spot. When the tea was ready, it was distributed to people in situ. This promotion was not too successful as the distributed tea was too hot to drink whilst the brewing process took too long, making those who would like to taste it impatient to wait.
The second method was used: tea was not brewed on the spot, but carried already brewed in big pans to the markets using open trucks. Again, this was successful because some of the tea spilled on the way to the market, mostly to the bad, pockmarked road condition in Jakarta at the time.
Then, an idea sprang up to carry the brewed tea in cleaned bottles. It turned out that this method was quite interesting for the customers because it was practical and ready to consume without the need to wait for the tea to be brewed.
Then, in 1969, the idea to sell ready to drink tea in bottle was f0rmulated, and in 1970, a bottled tea plant of PT SINAR SOSRO was established, the first ever of bottled ready-to-drink tea plant in Indonesia and the world.
