For me it's a particular grape. As a Sommelier, we supposed to be as objective as possible when selecting wines. Always keeping an open mind, trying different wines and don't let personal preferences distort your judgement. That can be hard to do sometimes when the guilty pleasure demon starts to take control of your thought process. It happens to me when I'm looking for a wine, I inevitably start drifting towards the California section in search of a good Zinfandel. It's my guilty pleasure for sure.
A great wine to serve with BBQ steak or take it to a Christmas party.
