A method of producing a hardwood pulp by mechanical refining is provided. This method comprises mechanically refining hardwood chips to produce a hardwood mechanical pulp and treating the hardwood mechanical pulp with one or more than one Family 11 xylanase at an amount effective to release a quantity of xylose from the pulp between about 0.5 to about 5.0 kg xylose/t of pulp. The enzyme-treated mechanical pulp is then further mechanically refined with a reduced demand for refining energy.
