Wine pairing.
Wine pairing is something most authors in this category want people to believe is very complicated to make sure that people buy their extremely expensive books. Those books normally go deep into every single detail that is of no use to a normal person, and after you have finished reading it you feel more confused than before. I know I did.
This book leaves out all the things that a non-professional really does not need to know because the difference it actually makes is barely noticeable. Instead, it is purely focused on helping you build up your confidence in wine pairing by providing you with:
An explanation of how different flavors affect each other and the pairing
Concrete examples of actual pairings
A list of ways to fix a food and wine pairing that did not turn out great
And so much more!
Wine pairing is a practical skill, and no matter how many books you ever read about it, you will not actually learn it until you start doing it.
