This is not a recipe book. It is a database of ingredient information that should assist the home or craft brewer in creating their own recipes in order to attempt the replication of commercial beers, many of which are no longer in production. Instructions on how to convert the supplied ingredient information into recipes customised to the brewer's own equipment and technique are provided. This book also provides inspiration to brewers wishing to experiment with different ingredients since it gives an interesting insight into how professional brewers have used them in their own brews. This third edition includes data for more beers and breweries including a new category for historical beers. Finally, this book should also be of interest to the discerning beer enthusiast who is curious about what goes into their favourite drink.
