Loose leaf teas are generally produced from single regions or even single tea gardens usually on steep slopes where hand plucking and gentle processing supports local communities and ensures only the best leaves make it to your cup.
The flavour of each tea is unique and can be enjoyed over multiple infusions if desired, making loose tea enjoyable and economical.
Mass market teas are generally blends from multiple regions where machine harvesting and processing is possible. Often stems and twigs accompany the leaves. Bagging tea requires resources and energy and conveniently masks quality.
Many bagged teas are single use, making the cost per cup of the higher quality mass market teas relatively expensive.
If it is quality and cost efficiency you're searching for, then loose leaf tea is the answer!
