From Whiskyfun,

Benriach 30 yo 1976/2007 (55.5%, OB, Richly peated, Port finish, cask #4469, 798 bottles) Colour: orangey – reddish. Nose: kind of a mix of both Port finished Benriachs we just tried. Obvious vinosity but it’s not unbearable. Once again, peat works as an anti-wine of some sort. Seville oranges, Fanta, pepper, Campari. ‘Pleasant’. Mouth: very close to the 1984, just a tad softer and rounder despite the slightly higher ABV. Ripe kiwis. Fructose, icing sugar, bubblegum. Finish: long but very sugary and uber-fruity again. Liquorice allsorts, jell-o, crystallised pineapples. One of the sweetest old whiskies I could try as far as I remember. Sincerely, I think this is excessive, but once again, just my opinion., no gospel and no bible of course. 77 points.

The aroma is rich, sweet, thick: a lot of old wood (barrel, varnish cabinet), sweet berries and berry jam, citrus (orange jam), a bunch of spices and chocolate, a light fruit sour. A drop of water does not change anything. The taste is sweet, spicy: wine notes, berries, oranges, spices (pepper, vanilla, cinnamon), chocolate, astringent astringent oak. A little bit burning. In the end a light smoky note. With water more even, soft, but more bitter. Aftertaste : astringent oak with light bitterness, berry jam, spices, a hint of smoke. Long, dense. Conclusion . A fine port wine mole. Thick, sweet, well-groomed. The aroma is very good, the taste is a little bit too sharp. A drop of water softens the taste a little, but adds unnecessary bitterness. Probably better without water. The score is 90 (n23t22f23b22).
