Insider knowledge: Heaven Hill 4 Year Old whiskey is named whiskey by virtue of the fact it's from America. If distilled in Scotland the spelling would be Heaven Hill 4 Year Old whisky, as opposed to whiskey.
This stuff is unbelievable smoooooth. BEST THING THATS EVER TOUCHED MY LIPS!!
Living in Kentucky for 32 years and being a bourbon aficionado let me warn you that Heaven Hill is not worth 16 pounds. Here in the states we pay approximately (US)$8 per bottle or perhaps (GB) 4L. It is very cheap, very dirty with a grit that will stay on the palette for hours. If you are mixing this bourbon fine but a true sippin' whisky this is not.
