To make a strong tea, use more tea leaves rather than cooking it for a longer time to avoid the bitter taste of the tea. Avoid distilled water, which can make the black tea taste flat. Preferably, use fresh water that has not been boiled earlier.

Chinese people add sweetening agents, spices, chocolate, or even rare herbs while brewing black tea. In India, milk and sugar are normally added to it. Some people add lemon or various herbs including ginger, cinnamon, cardamom, lemongrass, mulethi or holy basil (tulsi) to make chai tea or masala chai (popular spicy tea in India).
