Nowadays many distilleries use stainless steel fermenters and although these have the advantage of being easier to clean, Celtic Whisky Distillerie does not intend to compromise to the detriment of quality. It has, therefore, chosen to use Oregon pine fermenters, which contain a small colony of indigenous yeasts in addition to the fresh distiller’s yeast that they use. This helps to bring increased complexity and a specific character which is linked to the place of distillation.
