During the recent cold snap I inadvertently left a full bottle of sparkling wine outside the back door. It was frozen solid when I found it. I brought it inside and allowed it to defrost at room temperature. However, when defrosted, the bottle was no longer full (see photo, right). The bottle was corked and the cork was retained by a champagne-style wire cage. Both the cork and the wire appeared intact. Where has the missing wine gone?
