Systems and methods are shown for providing hot beverages using a beverage system integrated into a faucet. The faucet-integrated beverage system can include a hot water reservoir mounted under a countertop and fluidly coupled to a cold water supply line. The temperature and fill level in the hot water reservoir can be controlled using control circuitry provided on a circuit board communicatively coupled to the hot water reservoir and one or more sensors. A beverage supply line can extend from the hot water reservoir to a beverage dispensing unit, which can be coupled to the faucet or mounted on the faucet deck. The beverage system can also include an activation button mounted on the faucet or the faucet deck and communicatively coupled to the control board for initiating a brewing process.
