You could probably learn a lot from this little book even if you weren't going to plant a few vines, but if you're even thinking of growing grapes, this is a great little primer. It isn't going to make you a viticulturist, but it will prepare you for what you're about to get into. In the process, it will probably help you avoid more than a few mistakes.
The American Wine Society does select good authors. Each chapter is tightly written, adequately illustrated, and easily read and absorbed. Most are simply practical, as they should be. A couple border on being scholarly, which is a plus. Dr. John R. McGrew wrote six of the ten chapters. He's no T. V. Munson, but he is a professional grape breeder and a darn good winemaker, too. You can take his word to the bank.
If you think you might like to plant a few vines out back, buy this book. Read it cover-to-cover and then read Jeff Cox's From Vines to Wines. Long before the planting, you'll be dreaming of future harvests and vintage wines.
