Black Snake is produced from a vatting of casks finished in a sherry butt. Each cask used in this vatting was individually tasted and selected by Blackadder, as was the vatting before it was bottled.

Each individual vat of Black Snake has two-thirds drawn when bottled and then more whisky is added for further maturation. From time to time the sherry butt is renewed. All bottles from this vatting of Black Snake therefore contain some spirit that was in the original filling of the sherry butt.

Blackadder proudly calls their Black Snake whiskies "VENOM"
