Irish Breakfast. Our magnificent Irish Breakfast is a stout, robust blend of Kenya and Assam teas that have superb colour and are very full bodied. This low-calorie, refreshing tea is excellent in the early morning or afternoon and pairs well with milk and sweetener. It also contains minerals such as calcium, zinc and magnesium, which are especially great for antioxidant activity and oral hygiene. Research studies have linked black tea consumption with reduced stress, and reduced risk of cancer and heart disease.
