Mr. Towles, 'A Gentleman in Moscow' is a masterpiece. As geologist & wine lover your passage, "Near the end of the aisle, the Count turned down one of the rows. With a quick accounting of columns and shelves....he reflected how the curve of the glass fit in the palm of the hand... But inside? Inside this dark green glass..." a truly lovely description/expression of wine - would you comment on the roots of its origin?
