The brewing process is susceptible to personal preference. Water, a method for heating the water, something to heat it in, an Earl Grey tea blend and a pitcher or cup for the tea are typically required. Steeping time for Earl Grey tea is similarly controversial. Steeping for too long results in a bitter flavour; two to three minutes is a common recommendation, although some recommend as long as five minutes in order to "enjoy the full benefit of the citrus aroma."
