RankoIs this basically to make the brand sound more Scottish and thus lend an air of more authenticity?I think, given that Johnnie Walker is the largest selling whisky in the world, and that it has been around since 1820, that it has sufficient Scottishness about it to be as redolent of Scotland as Loch Lomond for many people, so I would think that the name change was for exactly the reason ed states above.
While Loch Lomond is a fairly old whisky, it hasn’t ever really been a famous or popular one (certainly not on the scale of a JW), and I think therefore that Hergé probably had never heard of it when the name was selected, and that it was purely coincidental that there really was a whisky of that name.
RexmilouJust out of interest www.lochlomonddistillery.com is the web site for this delicious brew favoured by Haddock (and Snowy)As suggested above, I think that the connection is an accident, and that the distillery has just adopted the connection as a (nice) advertising ploy. I’m not certain what they’d make of your assertion that they
brew it though - that’s for beer!
yamilahFor a picture of real-life Loch Lomond train containerI would suspect that this is some sort of publicity container, modelled after the book as a gimmick; distilleries tend to keep their transport fairly low key for security purposes, so slapping your name on a bright yellow tanker is a most unlikely way of sending thousands of pounds-worth of valuable spirit. It probably makes a nice talking-point for tourists though!
