Home Brewer's Recipe Database by Les Howarth
The Home Brewer's Recipe Database does not contain any recipes but has ingredient information that should permit you to design your own recipes in order to replicate thousands of excellent beers at home. Many of these beers are no longer commercially brewed so the only way to try to taste them now is to brew them yourself. This book also gives an interesting historical insight into the way that some British brewers have adjusted their recipes through the 1990s and can provide you with the justification to break some brewing "rules" with your own creations.
The Home Brewer's Recipe Database is available as an inexpensive e-book.
