The label: The first number "287" tells me the number of months the whiskey spent in the barrel. So in this case 23 years and 11 months. The "U" stands for Unpeated, ie without smoke. The combination "1.2" describes the barrel and stands for an ex-bourbon barrel and the occupancy, so it was once before (Scottish) whiskey after the bourbon in barrel. So it was a re-fill barrel. The last number "1824.3" tells me the year of foundation and the first month of production of the distillery, ie March 1824. Since I have barely dealt with Grain Whiskey so far, my research for the possible distillery took quite a while. In the end, I only found one Grain Whiskey distillery in Scotland, founded in 1824, the Cameronbridge distillery in Windygates, Fife. My conclusion:
Delicious, sweet drop. Works fine and light.
Immediately very sweet. Icing. Sweet popcorn. Behind it some pastries. I can hardly make out fruity notes. Overall, light and pleasant in the nose.
Mild and sweet but also warming. The popcorn is back. But also biscuits and vanilla. And then also some fruit, most likely apricot. Light mouthfeel.
A slight bitterness sets in.
Medium long and fruity.
