Check out the Pacific Rim Winemakers website for a unique forty page guide to Riesling, one of the most noble but confusing white grape varietals. This forty page guide offers a history of the grape, and describes its many rises and falls in popularity over the centuries. It's available online and you can request a free hard copy.
There's a concise but thorough guide to reading a German wine label and understanding the various classifications of their Rieslings. Other wine regions with strong reputations for making quality Rieslings are also profiled.
The booklet provides just the right combination of fun trivia, valuable information you can take with you to your favorite wine store, and a little wine nerd science if you are interested topics such as brix and must weight.
Pacific Rim makes some excellent Rieslings too, but fortunately, this guide doesn't hard sell you; it recommends Rieslings from wineries all over the world.
