What’s the difference between loose leaf and bagged tea?
High-quality tea is usually sold as loose tea. Additionally, tea in bags goes stale much more quickly because of its greater surface area (and hence greater exposure to atmospheric oxygen); and it tends to pick up odors and flavors from surrounding foods (and even from the box it’s in). Still, bags can be very convenient, especially if you are preparing tea away from home. It may be a good idea to store bagged tea in a tightly closed metal or opaque glass container to help keep it fresh longer.
