Claim:
1. A method for brewing a beverage at a brewing apparatus, the method comprising: retrieving a brew recipe for a brew cycle based on a selection for the brew recipe; calculating a pump duration based on a target fluid volume specified in the brew recipe; opening a first valve arranged between a reservoir and a boiler to dispense fluid from the reservoir into the boiler; closing the first valve in response to receipt of an output from a fluid level sensor within the boiler indicating achievement of a target fluid level within the boiler, the target fluid level specified in the brew recipe; actuating a first heating element thermally coupled to the boiler to heat fluid within the boiler; closing a second valve, the second valve coupled to an exhaust port of the boiler by a first fluid conduit; pumping gas into the boiler for the pump duration to dispense heated fluid from the boiler, through a second fluid conduit, into a brew chamber in response to receipt of an output from a temperature sensor thermally coupled to the boiler indicating achievement of a target brew temperature within the boiler, the target brew temperature specified in the brew recipe; and actuating a second heating element thermally coupled to the brew chamber to maintain fluid within the brew chamber at the target brew temperature.
