A beverage container with increased strength includes a generally cylindrical sidewall that is disposed around a vertical axis, and a bottom. The bottom provides a supporting surface and includes a bottom recess portion that is disposed radially inwardly of the supporting surface. The bottom recess portion includes a concave domed panel that is disposed a positional distance above the supporting surface by a dome positioning portion of this bottom recess portion. The domed panel includes a portion thereof with a curvature in the range wherein increases in the curvature decrease the static dome reversal pressure; and the dome positioning portion includes first and second parts thereof that are disposed at different radial distances from the vertical axis and that provide increases in both roll-out resistance and static dome reversal pressure. In various embodiments the first and second parts are circumferential, arcuate, at longitudinal; and, in at least some embodiments an increase in cumulative drop height is achieved as well as increases in both roll-out resistance and static dome reversal pressure.
