The seventh small-batch release from Wolfburn, Batch 458 has been crafted from a 50/50 combination of whisky matured for seven years in first-fill Pedro Ximénez sherry butts, married with lightly-peated spirit matured in first-fill bourbon barrels. These casks produced just 5,100 bottles in total and the result is a rich, sweet single malt with a superb depth of flavour.
