I tested it on Helsinki Uisge X 2020 and felt that it was one of the best whiskies I have ever tasted: both strong and complex. Sadly I haven't been able to find a bottle in Finland or even from German webshops.
I have a bottle of 2004 bottled in 2016, I picked it up in Glasgow, last year, but mine seems much lighter in colour, I have not opened the bottle yet...
Please do not compare colours of whisky from bottles that have different thickness. A sample bottle and full 0,70l bottle show colour totally diffenrently because 0,70l bottle has more light "resisting" particles. If you look into a whisky glass from above, the colour looks a lot darker when the glass is full than nearly empty. Just a tip to be more professional. Thank you for great whisky knowledge and videos !!!
