An integrated beverage infuser and lid are adapted for use with an insulated drinking vessel for brewing a consumable product, such as tea, in an insulated travel mug, tumbler, or the like. The lid includes a main body adapted for movable receipt on a drinking vessel that forms a downwardly directed, open-ended cavity. A fluid-permeable brewing basket defines an enclosable receptacle for removable receipt of the brewing consumable product. The basket is movable between a stowed position, substantially within the cavity above the liquid level of the hot water in the tumbler, and a deployed position, below and substantially outside of the cavity for submersion in the hot water contained in the drinking vessel. A lever arm forms a part of the transfer mechanism and has a portion that penetrates the main body to the outside thereof so that the transfer mechanism can be operated by an individual without removing the lid from the insulated drinking vessel, tumbler, or the like.
