A method and a system for treating betula wood to change the coloration thereof to resemble that of Cherry wood or heartwood of birch is described. The betula wood is introduced in treatment chamber which is under atmospheric pressure. Hot steam from a steam generator is introduced in the treatment chamber in a lower section thereof for subjecting the betula wood to be treated to a hot water vapor environment. The temperature and humidity levels in the treatment chamber are controlled over a time span until the betula wood is completely saturated with water and has obtained a desired color transformation. This color transformation is uniform throughout the thickness of the wood and thereby hi-lights the grain in the betula wood while at the same time changes its color whereby it resembles Cherry wood or heartwood of birch. The treated wood is then cooled in the treatment chamber and removed therefrom for further processing.
