The present invention relates to a Method for producing a flavour composition comprising providing a composition substantially comprising disrupted yeast cell walls and contacting the composition substantially comprising disrupted yeast cell walls with a glucanase and with an endoprotease, followed by separating a liquid fraction by solid / liquid separation to provide the flavour composition. Preferred enzymes are proline specific endoprotease and laminaripentaose-producing-beta-1,3-glucanase (LPHase).
