Coffee beans are the seeds of the coffee "cherry"; two seeds normally grow within each cherry.
On the tree, the beans are covered by the silverskin (a vestigial remainder of the fruit's development, also called the spermoderm). The silverskin is covered by a parchment skin (the endocarp), which is covered by a slimy layer (the parenchyma), surrounded by a thin layer of pulp (the mesocarp), all covered by an outer skin (the exocarp). These layers must be removed prior to roasting, though some silverskin often remains attached.
White tea is the uncured and unoxidized tea leaf. Like green, oolong and black tea, white tea comes from the Camellia sinensis plant. Oolong and black teas are oxidized before curing.
An Americano is a style of coffee prepared by adding hot water to espresso, giving a similar strength but different flavor from regular drip coffee. The strength of an Americano varies with the number of shots of espresso and the amount of water added.
