I finished The Widow Clicquot: The Story of a Champagne Empire and the Woman Who Ruled It by Tilar J. Mazzeo.
It's a book that will probably mostly be interesting to people who want to know more about wine history.
The book is as much about Barbe-Nicole Clicquot as it is about the developments in the wine industry and culture during her lifetime, some of which she initiated, including the use of flutes to drink champagne and a new process of removing the sediments from the bottle to produce clear wine.
But she also saw the introduction of industrially produced bottles, which were stronger than the blown-glass bottles that shattered easily under a buildup of pressure and the use of wine labels for branding and marketing purposes.
Most interesting, I think, is about the way the flavor of champagne changed from sweet to dry. Clicquot initially marketed to Russia, which preferred a sweet champagne (with as much as 300 grams of sugar), but when the British market became more important, winemakers had to shift their focus to drier drinks.
