A method for fabricating a beverage capsule comprises the steps of providing a first wall member (103) delimiting a cavity (106) and having a flange (109) disposed about an open end (108) communicating with said cavity (106), providing a quantity of edible granules (107) within said cavity (106), positioning a second wall member (112) upon said flange (109) and said open end (108) of said first wall member (103), attaching said second wall member (112) to said flange (109) at at least two regions of said flange (109) thereby dividing the flange (109) circumferentially into at least two attached regions and at least two unattached regions, applying a vacuum (119) between said first and second wall members (103, 112) creating a vacuum (119) within said cavity (106), and sealing said first and second wall members (103, 112) along said flange (109), thereby maintaining said vacuum (119) within said cavity (106).
