The present invention is directed to a mixer valve for e.g. dispensing flavoured beverages at the point of sale. An example of such a beverage is a flavoured cider, which comprises a base cider and a flavoured mixer. The present invention enables the user to select a desired flavoured mixer from a selection of mixers and dispense the mixed beverage, all with one valve. The mixer valve has an inlet body (10) and a selector body (30) having respective mating surfaces in sealing contact with one another. The inlet body (10) comprises a base liquid inlet channel arranged to receive a base liquid and having an opening at the mating surface of the inlet body, a first mixer inlet channel arranged to receive a first mixer liquid and having an opening at the mating surface of the inlet body (10), and a second mixer inlet channel arranged to receive a second mixer liquid and having an opening at the mating surface of the inlet body (10). The selector body (30) comprises one or more base liquid control channels, the or each channel having an opening at the mating surface of the selector body (30), and a mixer inlet selection channel having an opening at the mating surface of the selector body (30). The respective openings of the respective channels are arranged with respect to each other such that relative movement of the mating surfaces permits switching between a first selection configuration and a second selection configuration. In the first selection configuration the opening of the base liquid control channel or the opening of one of the base liquid control channels of the selector body (30) overlaps with the opening of the base liquid inlet channel of the inlet body (10), and the opening of the mixer inlet selector channel of the selector body (30) overlaps with the opening of the first mixer inlet channel of the inlet body (10). In the second selection configuration the opening of the base liquid control channel or the opening of one of the base liquid control channels of the selector body (30) overlaps with the opening of the base liquid inlet channel of the inlet body (10), and the opening of the mixer inlet selector channel of the selector body (30) overlaps with the opening of the second mixer inlet channel of the inlet body (10).
