I just saw this review by Roadfood's Jane and Michael Stern on NYTimes.com. Seems there is a new biography of the Widow (in French, Veuve) Clicquot that focuses "as much [on] Champagne itself as [on] the woman who helped elevate it to celebrity status."
Veuve is admittedly not my favorite Champagne, but Barbe-Nicole Clicquot was instrumental in turning Champagne into the international commercial enterprise it is today, and I can't help but be fascinated by that.
Sounds like my perfect book, and available at Barnes & Noble for less than 20 bucks (if you're a member, that is). Score!
