Green and white scorched with boiling water turn bitter. Use cooler water (around 70 to 80C) for them, see the temperature guide.

Leaving the bag or leaf in

Endless steeping is the top cause of bitter tea. Time it and remove the leaf, see why tea tastes bad.

Old, air exposed tea brews flat however well you make it. Store airtight and buy fresh, see how to store tea.

Tea is mostly water; reboiled, hard or chlorinated water spoils it. Fresh, filtered, boiled once, see best water for tea.

Choking the leaf

A tiny stuffed infuser ball cannot brew properly. Give leaf room in a big basket or pot, see using an infuser.

Wrong dose

Too little leaf = watery; too much = harsh. Set the dose deliberately, see weak tea.

Over milking and over sugaring

Drowning tea in milk or sugar hides it; often it is masking a brewing fault, see milk in tea and sugar in tea.

What it boils down to

Right temperature, timed steep, fresh leaf, good water, room to brew, correct dose, restrained extras. Use the symptoms as a diagnostic: weak means more leaf, not more time; bitter means a shorter, cooler steep, not more milk; flat means fresher leaf and better water. Fix those and most "bad tea" disappears, see why your tea tastes bad.
