According to the bottle:

Wood - FRENCH, AMERICAN & HUNGARIAN OAK
Nose –Complex and round, oaky spices with a warming toasted undertone.
Taste –Brown sugar, orange peel, soft vanilla and oaky spice; like a perfectly balanced old fashioned.
Finish –Long and round with rich spice

Interesting, I'll give you that. Next to no finish, though.

If you're in the market for a European, tannin-rich, non-sherry oak delivery system, I'd advise you to seek out the Glenlivet 15 "French Oak" at half the price.

Not overly complex, but friendly fruity with pleasant wood spices in the development and a long finish.

Wow plenty to enjoy here, powerful yet elegant with well balanced
fruit, oak and spice. Hard to fault and i can imagine this is going to
be a real crowd pleaser and i would say buy two (one to drink, enjoy and
share and one to keep with the other four in the series so you have the
complete set for a no brainer investment or superb tasting of five
limited edition Tomatin)

Aroma: complex and round, oaky spiciness with a warming toasty undertone.
Characteristics: raw sugar, orange peel, soft vanilla and spicy oak; like a perfectly balanced Old Fashioned.
Finish: Long and round with a rich spice. Original Tasting Notes. Wood, fire, earth, metal and water elements that are central to the oldest philosophies of civilization that enjoy incredible synergies. Together, they produce results that are far greater than their sum. This symbiosis - the 'five virtues' - is a concept synonymous with the ancient processes and materials used by the Tomatin Distillery Men. Water feeds wood; Wood keeps fire upright; Fire brings life to the earth; Earth produces metal; Metal collects water; And so the cycle goes on .... To celebrate the five virtues, the leading artist Eva Ullrich explored these interactions and their role in whisky production. The result is five remarkable works of art ... and five unique versions of the Tomatin Single Malt.

This expression acknowledges the difference wood makes to the whisky with a range of wood types.  it is a Limited Edition with 6000 bottles.  The packaging features work from abstract artist Eva Ullrich, who was asked to visually represent each of the five elements.
