2-3 cubes, pour just over the ice. Usually a glass a month or every couple months. Johnny Walker Black. Not because it's the best or tastiest, but that's what my long departed brother that taught me my trade drank and was the first whiskey I'd tasted.
Have friends & associates who are Scotch connoisseurs and aficionados and I think I could develop more exclusive tastes -very well may after I retire from my post-retirement job.
