The two old friends are:
Drink This - Wine Made Simple by Dara Moskowitz Grundahl (Click on the title to go to it's Amazon page). Published in 2009 it highlights useful information about the most popular types of wine and wine regions in easy to understand language. It's 12 chapters cover the nuts and bolts of drinking, buying, and tasting wine, 9 chapters on each of the most popular varietals (the type of wine), a chapter on the relationship of the cost of wine and how much you will like it, and a chapter on how to order wine in a restaurant. Each of the chapters on the type of wine will also give you some hints on how to identify the wine you are drinking, and how to host a wine tasting for that type of wine. An easy enjoyable read that dispenses lots of useful information with a lot of wit and personality.
My recent acquaintance is:
Wine Folly, The Essential Guide to Wine by Madeline Puckette and Justin Hammack. Published in 2015 I use this more as a reference as opposed to something to read cover to cover. How the book is formatted is pure genius. It uses graphics to explain fundamentals, styles of wine, and to explain the various wine regions. Since I purchased the book whenever there has been something I have not quite been sure about I have been able to quickly find the answer using this book.
Please let me know if you pick up any of these books and if you found them as helpful as I have.
