Speyburn is owned by the same company that owns the Pulteney, Balblair and Knockdhu distilleries, Inver House. However, they do not normally market Speyburn nearly as heavily as they do the other three. I'm not sure why, but I have a feeling they have Speyburn for blending.
Speyburn 10, 43% ABV
Single malt Scotch whisky (Speyside)
Nose: Very floral and sweet with a bit of a toasty characteristic.
Palate: Citrus (green apple, orange, lemon) followed by a bit of earthiness.
Finish: Citrus and some malt.
Rating (of 100): 86. This is not a very complex whisky but it is extremely drinkable and, at about $20/bottle, it's a great deal.
