Of the 4 or 5 bottles of personal Scotch blends I've got going, one in particular shines. It is the result of combining and recombining many bottles and probably is about 80% malt 20% grain whisky. (Some of the 20% may be Canadian whisky, but if so it doesn't matter). This has what I like in Scotch: a full body but not sweet; a light undertone of sherry; a top-note of peat and smoke; a mix of young and old; and a mellow quality. It has Laphroig (4 kinds), Lag 16 sherry cask and regular, Glenlivet 15 year old Limousin cask, Glenfiddich, Macallans of various kinds and many, many other whiskies, some drawn from the blended scotches I bought that later got added (e.g., Teacher's, Black and White, Chivas, Bell's). But when you taste it it has a real unity of Scotch whisky, no one would ever dream there are probably hundreds of whiskies in it. This resulted from trial and error but there is only genuine, good quality whisky in it and once you get the particular combo right it is a very good whisky indeed.
