Sirup Markisa GK uses selected fruits from passion fruit plantation on higher plains of Berastagi, North Sumatra. Using the flesh of these passion fruits, we extract the essence and add white sugar before bottling it as an all natural passion fruit syrup labeled as Sirup Markisa GK. The company, Sirup Markisa GK, has been established since 30 years ago. To ensure that our passion fruits are highly aromatic as well as rich in vitamin A and C, we work together with the local plantations in Berastagi. This recipe has been tested in Sirup Markisa GK’s own kitchen.
