Stop number 20 on the SDT is Glenrothes. This is a first for me from this Speyside distillery so I didn't really know what to expect going in. This NAS single malt was previously known as the Alba Reserve, the name was changed for better clarity as to what was actually in the bottle and I have to say it is a change for the better. 40% ABV and it appears to be natural color of a pale gold, but it is not stated anywhere if it is indeed natural that I could find. I do believe that it is chill filtered. This is matured exclusively in first and second fill ex bourbon barrels. The nose give the impression that there are both young and old casks at play here, but mostly young. Lots of coconut and vanilla with some dust oak. It's soft and creamy with a sort of berry medley. Raspberry, strawberry and blackberry. Floral honey and more vanilla and lightly toasted oak. There is also a waxy quality to it. It's a light nose, but very pleasant. The palate very much echoes the nose. Plenty of vanilla, floral honey and berries and cream. Soft oak. There is a subtle bourbon note and possibly sweet red wine that produces a dryness, very light though. Coconut and a mild spice cap everything off. Again, light but enjoyable. Light bodied with a creamy but somewhat thin mouthfeel, semi dry. The finish is medium length with soft oak and coconut fading away. Given the light color and overall light feel, I would think it's safe to say that there are many more second fill casks than first fill. Not knowing the rest of the expressions from this distillery it's hard to give an experienced opinion, but this one feels more like a Highland malt than a Speyside, closer to Tomatin or Glenmorangie than say a Cragganmore or Craigellachie. It's very approachable and would be great for warmer weather, even on the rocks on a hot day, relaxing in the sun. Great for the scotch noob too. 43% ABV would have been a better strength, but I think 46% would have changed it too much and taken away from its delicate nature. The die-hard Islay fans (like myself) may not think too much of this one because of its light and delicate nature, but it's a damn good dram for what it is. 3.75-4. Thanks to Ryan for the sample.
