Yes, Earl Grey tea does contain caffeine because it is usually made from black tea leaves. On average, one cup of Earl Grey tea contains around 40–70 mg of caffeine, depending on the brewing time and tea strength. Many people enjoy it as a balanced alternative to coffee because it provides gentle energy without being overly strong. Additionally, the natural bergamot flavor gives Earl Grey tea a refreshing citrus aroma that enhances the drinking experience. Some decaffeinated versions are also available for individuals who want the flavor without the stimulating effects.
