One of the most well known whisky brand is Johnnie Walker. Originally known as Walker's Kilmarnock Whisky, the brand is a legacy left by John "Johnnie" Walker after he started to sell whisky in his grocer's shop in Ayrshire, Scotland. Johnnie Walker continues to be blended in Kilmarnock, with a large plant just north of the town's railway station
I had an old Johnnie Walker whisky at my home. It was purchased by my father many years ago from a duty free airport. From the box, one can tell this is an old whisky. Notice there is no Johnnie Walker logo on it.
Johnnie Walker offered a few blends in their line of products and the most common found in this region should be the Black Label. The one I had now is the Extra Special Black Label.
The whisky was distilled and bottled in Scotland under British Government supervision according to the sticker on the bottle. It has 43% alcohol content
I believe all the Black Label blends are aged at least 12 years before they were sold. My Johnnie Walker could easily aged 25 years old by now.
