For the best flavor and health benefits, it's recommended to use fresh, high-quality green tea leaves or loose leaf tea. Bring fresh, filtered water to a temperature between 160-180°F (70-82°C) and steep the tea for 2-3 minutes. Avoid boiling water, as it can make the tea taste bitter. Use about 1 teaspoon of loose tea or 1 tea bag per 8 ounces of water. Adjust steeping time and tea quantity to your personal taste preferences.
