Arboralis, light from within the trees. This bright, golden single malt Scotch whisky is aged in ex-Bourbon and spanish sherry oak casks and is sheltered by tall, ancient trees lining the Victorian Gardens of the Glen Grant Distillery. With a soft aroma of fruit and honey, our golden liquid is matures until it achieves its signature complex elegance for which The Glen Grant has been celebrated for over 180 years. Arboralis delivers notes of creamy toffee and ripe pears, finishing with a long, satisfying hint of delicate spice.
