From the official website:

Magic Cask is perfect for those who appreciate lush fruitiness and fullness of body in their malt whiskies. Pour Magic Cask after dinner and savour its medley of autumn fruits and dark chocolate.

The ten Oloroso butts from which the “magic cask” emerged were sourced from Bodega José y Miguel Martín (J&MM). We requested a grade of American oak that would deliver moderate tannin and – for this parcel – a gentle seasoning process with Oloroso wine. Masters of their art, J&MM could dial up just the right levels of sweetness, tartness and spiciness, ensuring that cask #2 in particular delivered everything we desired from a Sherry cask.
