From the man from Macallan’s own mouth, he recommended a splash of water (1/5 to 1/4 of the whisky volume) to separate the various flavours a bit. That’s how I like it.
From an ex colleague (a Scot, obviously) who knew his stuff, as he used to be head of quality at one of the larger single malt producers whose name escapes me. He also suggested water, but then also said that he didn’t mind if you added coke, ginger, ice, lemonade…. as long as you were buying and drinking scotch as opposed to Irish or Bourbon or any other sort and keeping his old colleagues in a decent living.
Don’t see why you’d drink Bells any different tbh; OK it’s a blend but it’s still a blend of whiskies, it’s not a different drink entirely. And as most blends were conceived because a lot of single malts were too harsh, drinking a decent blended Scotch ‘neat’ might be an acclimatising step before stepping into the wider (and baffling) arena of ‘proper’ whisky.
