Magpie - have you tried the Cask Strength Laphroaig? It has a very strong peaty flavour and also blows your socks off at 57% maybe one to add water to
My current collection includes an Edradour 'Straight from the Cask' Sassicia finish and a Clynelish Chateau Lafite finish.Both seriously to be recommended.Also the Abelour A'bundah and Laphroigh.
Most whisky is matured in refilled sherry casks, a few use new oak. The colour in whisky comes from the tanins and residues in the barrel it's matured in.
I also like Springbank as it tastes mildly of glue.
Spending £300 on a bottle that tastes like TCP is going to be a waste of money if that's not his thing.
