How to extract juice from lemon grass

Updated February 21, 2017

Lemon grass juice, known as Nam Ta-krai in Thailand, is a popular Southeast Asian drink. Unlike with other grass juices, you don't need any special equipment to extract juice from lemon grass. The juice is made like tea: boiled in water and strained. Lemon grass juice can be consumed hot or cold. Add sugar or honey to taste for sweetness. Or have it plain and savour the natural flavour.

Cut the blackened root end off of the end of the lemon grass stalks. Rinse the lemon grass under the tap to clean it. Cut the stalks in half. Crush the stalks gently with the back of a cleaver or chopping knife to help release the juices.

Add the lemon grass to a pot of water at a proportion of roughly 1 cup of water per 42.5gr. of leaves. Place the pot on the stove and set the burner to high. When the water comes to a boil, reduce heat and simmer for 90 minutes to 8 hours, depending on how strong you wish the flavour to be.

Strain the juice into a pitcher. Throw away the leaves.

Add sugar or artificial sweetener to taste. Drink hot or chill and serve cold.


Consider adding a splash of fresh lime juice to punch up the flavour.
