Brewed drinks are beverages that are made by steeping, boiling, or fermenting ingredients in water. Common examples of brewed drinks include tea, coffee, beer, and kombucha. Tea is a popular brewed drink that is made by steeping the leaves of the Camellia sinensis plant in hot water. Coffee is another popular brewed drink that is made by roasting and grinding the seeds of the Coffea plant and then boiling them in water. Beer is a brewed drink that is made by fermenting grains, such as barley, with yeast and then boiling the mixture in water. Kombucha is a fermented tea-based beverage that is made by adding a symbiotic culture of bacteria and yeast to sweetened tea and allowing it to ferment.
