Putting a candle in an empty wine bottle has been a tradition for ages. It memorializes a special bottle (and the associated event) and is a simple and romantic way to add ambiance to a room.
But to have a candle that looks like a cork is a very fun play on the idea. I've started mine in a bottle of 45 North, a winery that references the 45th Parallel.
What luck that the labeling matches the room so perfectly.
