Stop number 19 on the SDT is Glenlivet. This distillery is in the Speyside region and is the best selling single malt scotch brand in the world. This expression is from the Nadurra (Gaelic for Natural) line. This one is a NAS that was finished in casks that previously held "heavily peated whisky". Where these casks came from and how long they were used in the finishing process is anyone's guess. Being "natural", this is a cask strength whisky at 61.5% ABV and is non chill filtered and natural color of a Chardonnay or golden straw. The nose has a fairly strong alcoholic burn if you dive right into it, but it's not that bad when you consider the ABV. Big citrus notes. Lemons and oranges primarily. Baked apple with cinnamon, subtle peaches and apricots come in after the citrus. A very light earthy note showed up after a few minutes...possibly peat? Vanilla buttercream and something like brown sugar dusted raisins. Adding water creates a malty character and an ever so distant tequila aroma. Stronger lemon notes. Better without the water though. The palate arrives hot and peppery, but tolerable. Soft peat smoke upon swallowing. A bright pop of citrus. Light oaky character and buttercream. With a little water I get some light exotic fruits like kiwi or maybe mango and coconut. The high ABV makes it hard to discern too many flavors, but there isn't a ton going on. Nicely warming though. The mouthfeel is very oily with some heat. Mouthwatering, turning semi dry. The finish is medium long with some heat, light peat and some citrus. This has been a perplexing bottle so far. When first opened, it was very easy to nose and drink. Warm and inviting. After pouring out 8 oz worth of samples and letting it sit for a week I went back to it. Maybe it was just me that day, but it set my nose and mouth ablaze! Almost undrinkable without a hefty dose of water. Let it sit another 3 weeks and it settled back down. It's a good whisky, but I feel it really NEEDS to be at cask strength, or at a minimum of 55%. Anything less and I think it would fall apart. I like it though. Good citrus flavors and enough peat to make you say yes there is some peat and not just meaningless words on the label. I don't feel that it's worth the price tag though. $90 locally is a bit high for what's in the bottle, even at cask strength. 3.75 to 4.
