I have tried a variety of Scotchs from Bowmore to Macallan and a lot in between. There is even a Glen Grant that is pretty good. But I have to say I have found nothing better than Glenlivet 18 Years Old —. For smoothness, taste, and all around quality this one can not be beat.
If you haven’t tried it, do. One caution, most bars do not carry the 18 year old, they have the 12 but it doesn’t compare.
