In many wine regions of the world the best type of wine is made every year. This is not true of Vintage Port. The Port producers do not 'declare' a Vintage Port in every year, only in some, when they believe the wine will have enough power and durability and excellence. For most Port brands, this happens about one year in three. There is an obvious question: which years did which producers declare? There is an obvious route to the answer: ask them. They sent answers, some slightly wrong, some very wrong. Correspondence went along the lines of "Your list doesn't include 1958, but your 1958 exists, and is good." Several previous books have included an appendix listing producers and years. Each has a list of producers by year, or years by producer, with no evidence and no verifiability. All those lists have errors, both of inclusion and omission. Port Vintages has evidence of which Port producers declared which vintages, and for each, all the facts and stories that could be found. It is organised into producer chapters, and within those, by vintage. So Port Vintages is the definitive chronicle of Vintage Port over the last 2 1/2 centuries."--Jacket flap
