I'm an amateur/home mixologist and I wanted a book to cross check some recipes and maybe learn some new ones. For the `home' bartenders out there, it's always a good idea to buy a book endorsed by one of the various professional associations (rather than some fancy recipe book full of drinks you will never bother making); this is compiled by The United Kingdom Bartenders' Guild. The edition I bought is from 2006 and I don't know if there are more recent ones, but I purchased a second-hand copy as it was a bargain.
The book has a very good introduction, which will appeal to the professional bartenders and home mixologists alike; it also explains the history of the mixed drink as a 20th century phenomenon. There's a handy section on essential ingredients and equipment which you can work your way through purchasing if you are determined build up a fully equipped home bar.
The recipes - unlike my other `bible' - are given in actual measurements, i.e. in centilitres. This makes things easier in a way, because you just pour and you are ready to go; however, I am used to recipes given in proportions (for examples, 8/10 Gin, 2/10 Vermouth) which makes it easier to adapt them to whatever size glasses you have or if you want to make a smaller or larger drink. Disappointingly too, most recipes don't have an accompanying photograph which sometimes is useful to know exactly what the drink should look like (some people for example use cream on White Russians so that the cream `floats' on the ice, etc).
Finally, in the final section there is also a short guide on wines and a glossary. All in all, I'd say that this book would make a valuable addition to a home mixologist's library.
