A spontaneously fermented wild ale with elderflower from Christophe Grellier’s certified-organic brewery in the French Alps. Brewed with pristine Alpine spring water from the Voirons mountainsthe same source as Evianthis beer is macerated in 1,000-liter sandstone jars before five months of barrel aging. Each vintage captures a specific moment: local microflora, seasonal elderflower, and the patience of natural fermentation. This is living beer in the truest sense, evolving in the bottle.
