Tetley Extra Strong is the brand's heavy duty everyday tea, bigger leaf, longer brewing, fuller flavour at standard tea bag pricing. The "builders' tea" answer for drinkers who find standard Tetley too light. Strong, malty, milk friendly, sugar friendly. The classic British workhorse with extra horsepower. Excellent for hard water areas where standard tea brews thin.

Why it works

For hard water areas

UK hard water (much of the South and East) extracts tea less effectively. Extra Strong compensates with more concentrated tea content. Many hard water area drinkers find standard tea bags brew thin; Extra Strong fixes this.

For workplace tea

The "tea round" benefits from strong tea, multiple cups, milk, sugar. Extra Strong is designed for this scenario.

For short steep times

Busy mornings, time pressed cuppa. Extra Strong delivers full flavour even at 2-3 minute steeps.

For milk and sugar drinkers

Stand up to substantial milk addition without becoming weak.
