Helles was first created in Munich n 1894, it is perhaps the most delicate beer imaginable.
Dornbusch managed to get a great balance of the three in this book, and he presents it in a style that shows that he downright enjoys his subject. The result is a book that, from a homebrewer's standpoint, is actually fun to read. But most importantly, you can make some pretty good brews from his recipes.
For the most authentic taste, I recommend incorporating decoction mashing. This subject is not covered in this text, but is in a book titled: NEW BREWING LAGER BEER.
Don't forget to drink to the foam (safely) and dance to merry music with a partner! Have fun. Auf Wiedersehen.
