It will definitely depend on the scotch. I mixed an Ardbeg Uigeadail into the bottle and it changed it considerably, but not in a terribly bad way especially after it sat for a couple weeks. But I think that's part of the journey. Right now, it's pretty heavy on the Islay (peated) scotch so it is definitely a bit weird at times, but it'll change over time with my palette, and I like that.
For example, right now I'm really into blended whiskies like Wolves [0], and as such the infinity bottle is starting to change from that characteristic Islay peat/smoke flavor profile to a more American whiskey profile.
I've found that writing tasting notes help me enjoy a weird whiskey a bit more, which includes the infinity bottle.
(But I will admit -- I have wanted to dump the bottle before! In that case, I just topped with bourbon and considered it a soft restart.)
