Jenise, the original quote added "-- the food of Aphrodite." It appears that way in My Life
by Duncan. Champagne was one of the joys of her life; she also wrote about the period before WWI -- "Now it seemed to me more natural to sip champagne and have some charming person tell me how beautiful I was."
Did you see the Vanessa Redgrave version of her life -- Redgrave got an Academy Award nomination and was wonderful in the film.
Thanks for posting this quote -- Duncan was a wonderful role model and even in turn of the century photos one can see her grace and style: http://www.isadoraduncan.org/about_isadora.html
