This is pretty good stuff.
I was a bit reluctant considering the price (€14.99) and not much else to go on, but, having previously tried their very good Highland Black whiskey though, I thought it was worth a shot (or two).
Once you open the screw top, the whiff of sugary maple syrup is surprisingly pleasant. This continues after pouring, although it's probably not an incredibly complex aroma, it compares well with some more expensive whiskeys.
The initial taste suffers a bit from a fairly noticeable alcohol burn, which can be a bit harsh, but swirling it a bit and leaving it to settle for 15 minutes or so helps considerably. I suspect that this continues to improve after the bottle is first opened.
The flavour of the spirit is very pleasant - oak wood and vanilla sugar, but a lot more rich and rounded compared to something like Jim Beam. I would say that this is a superior drink - certainly along the lines of a more expensive mid-range bourbon like Maker's Mark.
I haven't tried mixing this with anything else but it should work quite well, although it's definitely worth trying on it's own, neat without ice.
