IvabignI have put both a Bruichladdaich and Speyside in this guy, though not at the same time (and I know it sounds really messed up, but technically the Classic Laddie is a 5 year scotch that’s still excellent).
Its been more of an American bourbon container recently, but mostly that’s because I’m at home with my Glencairn glasses a lot this past year.
IvabignDidn't ask me, but as I'm using the flask for scotch (single malt) only :)
I tested the flask with Glenfarclas 105 (nice for testing due to ist 60%), later I used it for the 105/20y.
As this stuff is gone, the flask is now filled with Tomintoul Single Cask Sherry 2004/2018.
A second flask with the last nip of Glenfarclas 105/20 is stored in the car for cases of emergency :D
So yes, it's definitly fine for Scotch
