Yeah it's the green.At that price point probably the green "small batch". Black is 12yo. Red is 15yo darkest.
Currently working my way through a 15yo. Interesting combo of salt and sherry. I quite like it. 12yo is also very good.
If you're finding it too strong add a few drops of water. It's a pretty easy going whisky so maybe you just need a bit of time to acclimatise to it.I bought 2 bottles the 12year old hit me in a mess.its seemed very strong that a friend had a shot with me and refused a 2nd one
