The magazines Food & Wine, Wine Enthusiast, and Wine Spectator are good wine guides. Each is also a source for guides from other reputable experts found in print and on social media.
These three magazines have websites that contain information that is helpful in learning wine basics as well as keeping up with current news and trends in the industry. Winespectator.com features a page that includes wine basics, an ask-the-expert forum, a wine glossary and helpful videos. Wine Enthusiast rates and lists the top 100 wines each year. Foodandwine.com has a page with basics and various guides that feature top wine experts who regularly post on Twitter. The editors of Food & Wine also publish a yearly wine guide.
Hugh Johnson's Pocket Guide to Wine is a widely read yearly review. Recommended books on basic wine knowledge include "The Wine Bible" by Karen MacNeil, "Windows on the World Complete Wine Course" by Kevin Zraly, and "The World Atlas of Wine" by Zraly. "Wine Folly: The Essential Guide to Wine" by Madeline Puckette is another best-selling wine guide.
Wine bloggers are another good source for wine guides and basic information; each year Wineblogawards.org lists the top wine blogs. The Guild of Sommeliers, a group of trained wine experts, has a page on its website with content written by its members for the general public.
