Decaffeination is the removal of caffeine from coffee beans, cocoa, tea leaves, and other caffeine-containing materials. Decaffeinated products are commonly termed by the abbreviation decaf. To ensure product quality, manufacturers are required to test the newly decaffeinated coffee beans to make sure that caffeine concentration is relatively low. A caffeine content reduction of at least 97% is required under United States FDA standards. A 2006 study found decaffeinated drinks to contain typically 1–2% of the original caffeine content, but sometimes as much as 20%.

👉 Decaffeinated in the context of Coffee
Coffee is a beverage brewed from roasted, ground coffee beans. Darkly colored, bitter, and slightly acidic, coffee has a stimulating effect on humans, primarily due to its caffeine content, but decaffeinated coffee is also commercially available. There are also various coffee substitutes.
Coffee production begins when the seeds from coffee cherries (the Coffea plant's fruits) are separated to produce unroasted green coffee beans. The "beans" are roasted and then ground into fine particles. Coffee is brewed from the ground roasted beans, which are typically steeped in hot water before being filtered out. It is usually served hot, although chilled or iced coffee is common. Coffee can be prepared and presented in a variety of ways (e.g., espresso, French press, caffè latte, or already-brewed canned coffee). Sugar, sugar substitutes, milk, and cream are often added to mask the bitter taste or enhance the flavor.

Decaffeinated in the context of Herbal tea
Herbal teas or herb teas, technically known as herbal infusions, and less commonly called tisanes, are beverages made from the infusion or decoction of any herbs, spices, or other plant material in water that is not derived from the tea plant (Camellia sinensis). Many herbs used in teas/tisanes are also used in herbal medicine and in folk medicine. Herbal teas are not technically teas because they are not brewed from the tea plant.
The term "herbal tea" is often used to distinguish these infusions from true teas (e.g., black, green, white, yellow, oolong), which are prepared from the tea plant (Camellia sinensis) or, more rarely, its close relatives (such as Camellia taliensis). Beverages actually created from tea and combined with material from other plants are known as "blended teas", "scented teas", or "flavored teas". Examples include jasmine tea, genmaicha, and Earl Grey tea. Unlike true teas, most tisanes do not naturally contain caffeine (though tea can be decaffeinated, i.e., processed to remove caffeine).
