Going over my sample box, I discovered the last MOS single cask sample form the epic bottle share organized by Sjoerd a few years ago. Many of the bottles in that share were crackers, and I had high expectations from this one (and boy was I let down). Single casks are singular , that’s pretty much what you can say about them before tasting. Most are nice since IB tend to bottle good stuff, but once in a while they let an under par casks pass, and apparently this was the case here. Anyways, this is my first Glenallachie (I think), not sure what to make of it…
Glenallachie 16 yo 1995 (bott. 2011) , 53% cask #1257 (used to be € 60) 
Nose: sweet and fruity with quite some wood and corn syrup. Vanilla. Wood shavings and some pear and apple with fresh cereals. Malty and feels a bit young.
Palate: A bit rough starting sweet with herbal notes on the second wave. Pepper and hints of mint sawdust and dry wood. Youngish and alcoholic at times with some grainy notes. Not very refined.
Finish: dry wood. Bitter grapefruit pith.
Quite disappointing, to be honest. Feels younger and rougher than I’d expected. it’s way sold out years ago, but if you have a bottle, keep it closed
