A. D. Rattray

I first got to know family-owned, independent bottler A. D. Rattray at a whisky tasting in Glasgow’s Good Spirits Co a number of years ago. The line-up on the evening in question featured drams of Stronachie and Cask Islay alongside a number of single cask expressions from various distilleries. Hosting the tasting was none other than Iain Croucher, who would later go on to create North Star Spirits. Iain explained that A. D. Rattray kept a supply of casks at their Ayrshire-based ‘Whisky Experience’ from whence customers could fill their very own unique bottle of ‘cask strength’ single malt. The company have gone on to become distillers in their own right with the launch of the Clydeside in Glasgow, but the practice of offering single casks to customers continues today, with some interesting experiments taking place along the way.

It was with some delight that I received a package containing samples of the most recent of these experiments. The Octave Project is a bold exploration of the occasionally murky world of cask ‘finishing’, with a single malt from the Arran distillery aged for 6 years in a 250 litre Bourbon Barrel before being divided and transferred to smaller 50 litre Octave casks. A fifth of the malt remained in the original barrel, while the rest is shared between casks that previously held Pedro Ximenez Sherry, Oloroso Sherry. Rioja Wine and Rum.

These smaller casks are an effective way of speeding up the effects of finishing due to the higher liquid to wood ratio and have helped, in this case, to create five fascinating variations of what is essentially the same single malt…


Original Bourbon Barrel

Smell: Vanilla, Cream, Peach, Orange, Lemon, Apple and Pepper.

Taste: Caramel, Honey, Vanilla & Sea Salt, Biscuit, Orange, Oak, Pepper and a touch of Chocolate.

Thoughts: Each expression in the range comes in at £57. The original bourbon-matured version is a fine dram in its own right and, though young, I’d be happy paying £57 for it. The problem is, I suspect there may be more interesting options later in the range.

Though perhaps not as exciting as others in the pack, it is still a young and powerful Arran that has enjoyed a successful maturation in a good quality barrel. As a result, the distillery character is undoubtedly at its most noticeable here and therefore perhaps would appeal most to real fans of the official core range.


Pedro Ximenez Octave Finish

Buy Here

Smell: A little subdued at first but after some time in the glass there’s notes of Raisins, Prunes and Treacle with underlying Vanilla and Green Fruits.

Taste: Salted Caramel and Ripe Berries, Red Apples and Plums, Sea Salt, white Pepper and Oak.

Thoughts: Well now, this would certainly be worth a purchase at £57. What a difference! The PX influence brings an extraordinary explosion of flavour on the palate, though the character of the spirit does slowly become apparent after some time in the glass. It’s a real star of a whisky but definitely not one for those that like their drams soft and subtle.


Oloroso Octave Finish

Buy Here

Smell: Christmas Cake, Cinnamon, Orange, Toffee Apples, Vanilla and Fresh Fruit.

Taste: Raisins, Bitter Dark Chocolate, Nutmeg and Ginger, Orange and Oak.

Thoughts: The combination of Bourbon maturation and Oloroso finishing is rather commonplace among many distillers today but here we have a particularly well executed example. It’s a little less explosive than the PX alternative but there is still a dram of robust flavour here. Rich and sumptuous, it is a dram to take one’s time over with every drop demanding to be savoured.


Rioja Octave Finish

Buy Here

Smell: Lots of Fruit – Figs, Plums, Orange, Peach, Apple, Pear… Along with Toffee and Caramel and some exotic Spice.

Taste: Oak and Spice with more Fruit.. Orange, Red Apples, Berries and Raspberry Jam with the same Toffee / Caramel characteristic found in the nose.

Thoughts: This comes across as a dram that might take a little time to truly appreciate. It’s got some potential to be the most rewarding of the range, if shown a little patience. Each return to the glass seems to unveil something a little different. We know already that Arran works well with red wine, so good is the official Amarone bottling and this shows us another demonstration of the spirit’s versatility.

Mouthwatering Aroma combines with a complex and unusual array of flavours to create something really rather special.


Rum Octave Finish

Buy Here

Smell: Definite touch of Rum around the nose, then Apple, Pear, Orange and Peach… Honey with a Grassy Menthol-like freshness and perhaps a slight touch of Chocolate.

Taste: Rum impact seems more prominent than the nose with lots of Spice – Nutmeg and Clove, then Toffee and Chocolate Raisins, a touch of Honey and more Orange.

Thoughts: The impact of the Rum octave seems less dynamic than that of the wine casks, making this the most like the original bourbon. There is without a doubt however, an additional layer of complexity brought on by the secondary maturation and while not as instantly adorable as say, the PX, it is a nevertheless a comforting, warming sip.

The Octave Project is easily one of the more exciting bottling series I’ve come across recently and it’s especially rewarding when you can compare the differences between the samples. Of course, experimentation is all well and good, but palatable results are required at the end of it all and here A. D. Rattray have not failed.

The original Bourbon is a pleasantly creamy yet fruity dram, the Oloroso highlights exactly why this Sherry wood is in such high demand with distillers worldwide, the Rum and Rioja both offer something a little outside the norm but for me, the real standout was the incredible Pedro Ximenez finish, a dram with such an intensity of flavour that it will live on in my memory for quite some time to come.

***Full Disclosure: the good folks at A.D. Rattray sent me this sample set for review purposes. As always, I have attempted to remain as impartial as possible.
