A unique seven-colour tea, offering varied flavours in a glass or cup, is now available in the Bangladesh capital Dhaka.
About a decade ago, a tea vendor, Romesh Ram Gour, in Moulvibazar district, which is known as the tea capital of Bangladesh, developed the technique of layering different coloured layers of tea in a glass. Each layer differs in colour and taste.
Tea connoisseurs in Dhaka used to travel hours to Srimongol town, about 200 km from Dhaka, just to take a sip of the legendary tea at the store of Gour who always makes his concoction away from prying eyes.
He never unlocked the secret to his rainbow brew that he invented but several copycats from the region succeeded in creating seven-layer teas, which made Gour famous home and abroad.
Saiful Islam is one of those successful imitators who opened a tea store in Dhaka and his Rangdhonu (rainbow) seven-colour tea store in Dhaka's eastern Taltola market is a hot tourist attraction.
Like Gour, Islam doesn't want to reveal the secret of making the seven-layer tea and doesn't allow anyone to stay at his tea-preparation room.
He said about 10 years ago, a tea vendor in Moulvibazar's Srimangal area developed the technique of making such tea.
"From there I have somehow acquired the secret technique of layering seven coloured tea," he added.
"Later I moved to Dhaka and opened a store to sell the seven-colour tea."
He said the most interesting thing is that different layers is separate and not mixed together.
"We mix different types of locally and China-grown tea -- three black teas and one green tea -- with milk and various spices. Each mixture has a distinct colour and taste, and I pour one on top of another to create seven distinct bands of colours including orange, black, white, strawberry, milk and green.
"The taste of each layer is different. It is organic. No chemical is used." Islam said he created a white layer blended with ginger, which is especially good for health.
