Earl Grey is a wonderful and soothing tea any time of the day. 
 

Hot tea brewing method: Bring freshly drawn cold water to a rolling boil. Place 1 teaspoon of tea for each cup into the teapot. Pour boiling water into teapot. Cover and let steep for 3-7 minutes to desired strength - the longer the steeping time the stronger the tea. Although milk and a dash of sugar may help enhance the flavor of this tea, it is perfectly acceptable to consume it ‘straight-up.’
 

Iced tea brewing method: (to make 1 liter/quart): Place 6 teaspoons of tea into a teapot or heat resistant pitcher. Add 1 1/4 cups of freshly boiled water. Steep 5 minutes. Quarter fill a serving pitcher with cold water. Strain the tea into the pitcher. Add ice and top-up with cold water. Garnish and sweeten to taste. [A rule of thumb when preparing fresh brewed iced tea is to double the strength of hot tea since it will be poured over ice and diluted with cold water]. Please note that this tea may tend to go cloudy or ‘milky’ when poured over ice; a perfectly normal characteristic of some high quality black teas and nothing to worry about!
