Beverage machine and method for brewing beverage

A beverage machine, comprising:

• a beverage distribution pipeline connected between a beverage dispensing outlet and a brewing chamber of a brewer for preparing a brewing beverage, for delivering the brewing beverage to the beverage dispensing outlet;
• a heat exchanger, the heat exchanger being provided with a heat exchange channel, a portion of the beverage distribution pipeline passing through the heat exchanger, the heat exchange channel surrounding the portion of the beverage distribution pipeline, the portion of the beverage distribution pipeline being fluidly isolated from but thermally in contact with the heat exchange channel, the heat exchange channel being provided with a channel inlet and a channel outlet, and the channel inlet being connected to a first pipeline and a second pipeline;
• and
• a controller, wherein 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, thereby enabling the heat exchange channel to selectively introduce either a heating source through the first pipeline or a cooling source through the second pipeline, to dispense the brewing beverage heated by the heating source in the heat exchange channel or the brewing beverage cooled by the cooling source in the heat exchange channel at the beverage dispensing outlet.
