Tops Jamaican Fevergrass Herbal Tea is a traditional Jamaican bush tea — fevergrass (also known as lemongrass) is the citrus-aromatic grass long part of Caribbean bush-tea tradition. The cup is bright, clean, and slightly perfumed without the sharpness of citrus. The 60g pack contains tea bags ready to brew. Brew in freshly boiled water for 4 to 5 minutes. Caffeine-free. Particularly good after a meal or in the evening; equally pleasant chilled over ice on a hot afternoon. Tops is a UK Jamaican tea brand specialising in single-herb bush-tea traditions.
