One of my team mates when playing rugby had a father in law who was a blender for a distillery somewhere in Scotland.
He used to samples sent down in plain numbered small sample bottles.
We used to meet at his house on route to Cardiff for internationals for breakfast....
Liquid accompaniment too.
Some of the samples were absolutely stunning.
Many purely experimental with a range of tastes.
I am not a big whiskey drinker but do enjoy some tots.
Highland Park/ Chivas/Penderyn.
Penderyn do some nice ones theses days, one made due to a mistake in the maturing barrels used but kept as a going version. May be their Madeira version, and recently finished my bottle of it.
