This remarkable pétillant of Chenin Blanc comes from forty year old vines planted over schist and was aged on the lees in bottle for just over a year before disgorgement. Jérôme harvests the fruit for this wine at the same time as Coule de Source, resulting in an incredibly vinous take on the genre, that unlike many, is true to both variety and terroir. A brilliant gold in the glass, it is wonderfully delicate, mineral and fine.
