......And somewhere on a whisk(e)y forum there's a few folks having a laugh about a description they saw for the new bike from Company ABC

"You won't believe the detail they go into about tyres!"
What can seem pretentious at first starts to make sense with a bit of experience and knowledge. But it's an entirely personal experience. Your vocabulary will be different to mine, neither is more correct than another.
Don't forget too, that there are people who make a living writing about these things. They have to justify their wages!
What a great gift you have for the winter! It's a pity it's only 5cl. I'd suggest holding some back and trying it again a few months down the road. You might surprise yourself!
Do you have a proper tasting glass? Well worth an investment!
You can also help train your palate with.....anything. Taking a moment to consider the taste, layers of flavour, the texture....good for the palate and the mind!
There's also an opportunity to do a bit of research into the history of the distilleries and the whiskies. That gets really interesting and gives a perspective to cut through the bullcrap! Prohibition era Mafia connections (Laphroaig), modern day Mafia connections (Macallan), terrorist suspicions (Bruichladdich), breaking the mould (Glenfiddich).
On a side note, Glenfarclas is one of the least pretentious whisky makers out there! I recall reading an hilarious interview with the current GM who was railing against some of the marketing language used to promote his whisky.
Last time I checked they were the only Scottish distillery that gave us the option to try a whisky at different ages - the only difference being the age. The 25 year old is interesting, and complex but like many a cyclist, experienced and past its peak
Finally - what a great theme for a cycle tour!
Good luck and I hope you enjoy your gift and where it can take you!
