Glen Garioch (pronounced "Glen Gerrie") is an assemblage of gray granite buildings located in a small glen near Aberdeen. It has been producing whisky, though sometimes sporadically, since 1797. It is quite traditional, still producing its own maltings. It produces a peaty, smoky whisky that takes one back to an earlier time when such whiskies were quite common in the Highlands. Though quite traditional in the way it produces whisky, it has been recognized for technological innovations that recycle its waste heat to warm its greenhouses, where flowers and vegetables are grown and ripened-- including 150 tons of tomatoes a year."
Never had it but the greenhouse is a great use of "waste heat" put to good use....hmmm...I assume this be implemented an other distilleries.
