Peaberry, known in Spanish as caracolillo, is a type of coffee bean. Normally the fruit ("cherry") of the coffee plant contains two seeds ("beans") that develop with flattened facing sides, but sometimes only one of the two seeds is fertilized, and the single seed develops with nothing to flatten it.
Coffea arabica, also known as the Arabica coffee, is a species of flowering plant in the coffee and madder family Rubiaceae. It is believed to be the first species of coffee to have been cultivated and is the dominant cultivar, representing about 60% of global production.
White Coffee is coffee roasted half of the way through and to a lower temperature. By roasting it to this much lower temperature, you get a whitish colored bean that is higher in caffeine because you roast out less caffeine. This results in a very nutty and sweet taste profile much different from traditional coffee.
