Many thanks, Debbie
I work out that Pinot Grigio is mentioned just twice in the trilogy but the couple do drink many unidentified 'white wines'
Chianti doesn't appear at all...but red wines make few appearences.
In Fifty Shades Darker the couple's wine choice widens with Australian, California and South Africa being poured. And this time some wines are named...Wines of Fifty Shades Darker
