Made by Jacques Perritaz in Fribourg, Switzerland; Jacques' cider mentor was Eric Bordelet. This cider is made from apples from the 120 year-old farm of Helmut Muller in Thurgovia, where he more than 300 varieties of apples, 100 pear varieties, 15 cherry varieties, and 60 plums varieties. It has been run organically since the eighties, and been certified since 2009. Labelled as demi-sec, this has delicate aromas of apples witha hint of ash with great fruit, no astringency, and the least pronounced saltiness. The name comes from a type of local butterfly that feeds on the juice of fallen apples.
