Dear Dr. Vinny,
What is the purpose of the two tiny holes in the capsule just above the cork? Some bottles have these holes and others do not. Please explain. Thank you.

It’s going to seem so obvious when I tell you. Those perforations just act as a vent to allow air to escape when the capsule is put on. They’re meant to provide a tighter, wrinkle-free fit.
