An integrated beverage infuser and lid are adapted for use with a drinking vessel for brewing a consumable product, such as tea, in the drinking vessel, such as a travel mug or insulated tumbler. The lid includes a main body adapted for removable attachment to the drinking vessel. A fluid-permeable brewing basket defines an enclosable receptacle for removable receipt of the brewing product. The basket is movable between a stowed position, close to a lower surface of the main body and above the level of liquid in the drinking vessel, and a deployed position, spaced farther apart from the lower surface of the main body for submersion in the liquid contained in the drinking vessel. A flexible attachment member attaches the brewing basket to the lid main body. A sidewall recess in the main body retains the flexible attachment member when the brewing basket is in the stowed position.
