Blossa Glogg.

Blossa Glogg (aka vintage mulled wine) launches an annual edition every holiday season with a new flavor and bottle design.The brilliant minds at BVD came up with a fantastic solution to make the product both highly collected and covetable: keep the bottle shape the same while changing up the type and colors to reflect the year's design and flavor. Apparently Blossa has had some excellent results - the past two years it sold out in the first two weeks.
