Benromach 10 is a personal favourite, very well rounded and a bargain for £35. Something different from your usual well known distillery’s offerings.
Springbank 10 is another that is a bit different and really well rounded.
I just picked up a Glenlivet Nadurra 16 reduced to clear in my local Tesco for £23. It’s cask strength and isn’t filtered – really nice for the money.
Lagavulin 16 is hard to beat if he likes peated whisky.
Hibiki 12 is a Japanese blend but it’s absolutely gorgeous and comes in a fancy looking decanter style bottle. Only problem is it’s £36 for 50cl
As someone else has mentioned Tamdhu is a lovely sherried speysider.
