Peaty water ought to be classed as a luxury. You have spent a day on the hill, a’chasing the deer. This means coping with the rigours of topography, the cunning of the quarry and the vindictiveness of the elements, though that has its compensations. Rain keeps away the midges. You arrive back damp and knackered, but there is an instant restorative: a bathful of broiling peaty water, with a glass of peaty whisky as a chaser.
