This book was published in 1992, you can get just about anything these days as far as ingredients, and equipment is so much better. With that said, the history and text on Weizen bier is excellent. Take note the line about "never" put a lemon slice or any other fruit in your weiss bier, it would be an insult to the Bavarian brewer, prost to that one Eric ! Of the many times I've been to Germany only in the recent past have the bar tenders been offering a lemon slice due to the demand of tourists. Read this book and learn about a great bier.
