Normally, that might be enough to just recommend the 25 Year over the 18 Year, but then you have to consider the bottle price: The Bunnahabhain 25 Year Old costs around $650 US(!), with some stores marking it up to $900. Compare that to the Bunnahabhain 18 Year, which is $150 a bottle and the value just isn’t there for the 25 Year. It’s not 400%+ better than the 18 Year. If you have the extra money laying around, it’s a good bottle, but it feels a touch overpriced.
Immediately there’s dark stone fruits, plums, cooked figs, raisins. Not as intense as GlenDronach’s 20+ Year Single Cask bottles, but still quite pleasing. No uncomfortable ABV singe either.
Nice, thick, viscous mouthfeel. There’s some easy ginger spice, the ABV is nicely balanced, with nothing distracting. There’s some raisin and sherry sweetness, caramel, and then that distinctive Bunnahabhain / Islay coastal salinity, which makes it really enticing.
However, the strongest note on the mid-palate until the finish was chocolate coffee(!). There was some light bitterness, but not as heavy and intense as some other distillers. It wasn’t oaky (great), but it had this distinctive taste that evoked coffee.
Gentle long finish. No woodiness, but it was smooth, more of the coffee finish, some bitterness, dry, not much sweetness here.
