Similar to wine, tea is affected greatly by the climate in which it grows.
Differences in soil and weather conditions give us a rich mosaic of tea's many
varieties and flavors. Altitude also plays an important role. Tea plants grow
slower at higher altitudes, producing leaves with concentrated flavor. Gourmet
tea varieties are almost exclusively made from these high-grown leaves. The
more common low-growth varieties typically end up on your supermarket shelf.
