La Grange Tiphaine is the top estate made by Coralie and Damien Delecheneau, and this Montlouis is one of their most intense, most complex wines. "Clef de Sol" means "Key to the sun", and it makes sense when you try this wine filled with ripe pear, apricot, and strawberry fruits, all singing with acidity that lifts this unabashedly rich wine into the sky! (figuratively speaking, of course).
