Even besides the obvious red wine colour, the nose and the first sip screams wine cask matured. However even though I usually do not like wine matured malts, this one is quite nice. Less into tartness and astringent tannins, and more into sweetness and oxidative qualities à la Oloroso.
However, as others have noted there is little complexity under the cask. Obviously this is a Scotch whisky, but other than the moderately high ABV and some nice barrel-induced notes, the majority of the heavy lifting is done by the wine. Maybe the spirit gave some apple-ish notes, but it's not the most colourful malt.
While tasting, this bottle instantly came into mind (from among a few dozen samples on my desk!) Probably because there weren't many wine matured specimen in the first place, but the softer-than-usual malt of Macduff probably also gave a tip.
A Scotch for people who do not like Scotch, but also a wine cask for people do not usually like wine casks, I might add.
