The present invention provides a beverage mug for containing hot or cold beverages without substantial spillage. The beverage mug comprises an endless outer wall having an open top and bottom, and an endless inner wall having an open top and bottom, each of which comprises a base portion, a mouth portion, and optionally, a neck portion. The base portion of each of the inner and outer walls is substantially wider in the direction generally perpendicular to the vertical axis, i.e., when viewed from the top, than said mouth portion from the same perspective, so as to impart stability to the mug and resist tipping of the mug. Advantageously, the first and second walls define an insulating space sufficient to retard heat transfer to or from a beverage contained in the mug. In preferred embodiments, the mug is formed in four sections, joined in three joints to form the mug, comprising the outer wall, the inner wall, a base portion joined to the inner wall and a base portion joined to the outer wall. A method aspect of the invention is also provided.
