Which is the correct method for making a Grande teavana hot brewed tea (black or herbal)?

The correct answer involves using 2 tea sachets and steeping for 5 minutes when making a Grande Teavana hot brewed tea, whether it's black or herbal. This method is appropriate because using two sachets ensures that the flavor is rich and robust, which is important for offering a satisfying tea experience, especially in a larger size like a Grande.

Steeping for 5 minutes also allows for optimal extraction of the tea's flavors and beneficial compounds, which can enhance the overall taste. The specific steeping time is based on tea industry standards to ensure that customers get the best possible flavor profile, particularly for stronger teas like black tea. Herbal teas also benefit from a longer steeping time to fully release their aromatic qualities and health benefits.

Using just one sachet or a shorter steeping time may lead to a weaker flavor that does not compare well with Starbucks' standards for quality. The combination of using two sachets and steeping for 5 minutes strikes the right balance for delivering a quality cup of tea that meets customer expectations.
