Yes, Johnnie Walker is highly rated for a common scotch.
If you want to be exotic, 21 yr old Glenlevit would also be quite nice.
He may also enjoy a single malt scotch such as Laphroaig.
To me, the single malts tasted like iodine, haha.
Laboring certainly does. It’s the peat and taste of t h e sea. I think it is the most foul tasting whiskey I have ever tasted. But there are people who love it and similar single malts. I prefer Oban 18 which has more fruit and no iodine taste.
