Abstract: A beverage machine includes: a beverage distribution pipeline connected between a beverage dispensing outlet and a brewing chamber of a brewer for preparing a brewing beverage; a heat exchanger provided with a heat exchange channel, a portion of the beverage distribution pipeline passing through the heat exchanger, the heat exchange channel surrounding the beverage distribution pipeline, the beverage distribution pipeline being fluidly isolated from but thermally in contact with the heat exchange channel, and the heat exchange channel being provided with a channel inlet connected to a first pipeline and a second pipeline; and a controller. The controller, in response to an adjustment signal characterizing an output beverage temperature, controls selective connection between the channel inlet and either the first pipeline or the second pipeline, to heat or cool the brewing beverage.
