It is a qoute by Galileo Galilei, and poetically describes wine the way he saw it. Something fantastic, the light from the sun caught in a bottle and kept there by water.
Yes, it is, Lilly! Thank you to all of you for the explanation... I probably haven't got so fertile imagination as Lein does, but I really can understand what she thinks...
It is beautiful metaphor indeed. I have been thinking in the right direction before, but couldn't believe somebody could think about a wine in this way!!!
