This bottling is assigned to the "House Tully" which has a nasty looking trout on the insignia. I guess it's linked to Glendullan due to the distillery being on the River Fiddich in Dufftown, Speyside (though I hope the trout there are happier). Glendullan was established in 1897 by the Aberdeen-based blenders William Williams & Sons, with a modern distillery built next door in 1960 (the original building closed down 20 years later). Diageo now bottles the spirit as "Singleton of Glendullan"). If anyone knows what "Singleton" means, please share. The Game of Thrones bottling is called "Select" (but still has the "Singleton" moniker) and is NAS.
The colour is a rich copper. On the nose I get a nice burst of orange, with underripe pear, roasted green pepper, plum, toasted pine nuts and barley sugar. The orange (more like marmalade, I guess) is quite dominant. Hint of fennel. A bit too much caramel. A bit maltier with water, which also brings out woodsmoke. Standard but decent Speyside malt.
On the palate there is some honey woven through the malty sweetness, with cloves, blueberry, green apple, white pepper and more orange. Thin mouthfeel. Lemon drops. More caramel (which somehow deadens everything), but livelier with a drop of water.
The finish is medium-length but a bit nondescript with a bit of citrus, cinnamon and oak. Nothing terrible but nothing transcendent about this single malt - pleasant enough and easy to drink, but I'm not transported to fantasy-dragon-land.
