Claim:
1. A container comprising: (a) a glass comprising a bottom, a sidewall extending from the bottom and terminating in a rim; the rim defining an opening in the glass; (b) wine in the glass; and (c) a film lid detachably sealed to the rim of the glass and covering the opening at a distance above a top surface of the wine; the lid comprising a bottom face that defines with the top surface of the wine a head space within the glass; the lid being substantially planar but comprising at least one deformation in a portion thereof that causes the portion to deform and to impinge into the head space when there is a reduction in pressure in the head space that causes a pressure differential between the head space and an environment outside the glass to exceed a threshold value, wherein the impingement substantially reduces a volume of the head space and limits the pressure reduction in the head space.
