5. Wine Book - There are several good ones out there... The one I just finished reading is Billionaire's Vinegar by Benjamin Wallace
4. Wearables - Where can you go wrong here?
3. Port/Sherry - Smooth and also well received.
2. DeCanter - Nothing fancy, just one that is easy to work.
1. Subscriptions - Wine Spectator, Food and Wine... there are great ones to choose from.
