What’s that little plastic thing in the neck of my bottle of (Buchanan’s) scotch?
Now I shall sip while others ponder.

It moderates the flow so that you can pour as a measured pace to accurately gauge the amount and in most cases it improves your aim. It’s been many years since I’ve been a bartender but my recollection was that three “glugs” equaled an ounce of liquor.
I see. So it replaces that spout thing that barkeeps insert into a bottle when they open it. This is my first bottle since back in the day before, I guess, they began using this thing. I wonder what it’s called.
I don’t mix anything with the scotch except a little water, but it works pretty good.
Anyway, thanks Nunzio.

To be clear, it’s not a scotch-specific thing. It’s usually found in larger bottles of booze. You rarely find them in bottles of good scotch.
Like with wine, and cork vs plastic.
Munch’s post aroused my curiosity, so I checked here.
I got it at CVS pharmacy in a gift box with two nice glasses for $28.
I am not an expert.
Not as much anymore. Lots of very good wine is being bottled with twist off caps these days.
Though it makes sense to be on bigger bottles as, we gather, it is there as a barkeep’s tool of convenience. Three glugs saves time compared to measuring it out each time and are probably a bit more precise than counting the seconds on a free pour. (Although I’d guess an experienced barkeep would do just as well with a free pour.)
Yeah, twist caps. That’s what I meant. I prefer a cork if I have a guest, twist otherwise.
There is, I think, a pour spout that stops at a shot.
I’ve often wondered why optics aren’t used much in the US.
Here’s one that I found.
The only bar owner that I’ve known used these and he was known for strong drinks. He often worked the bar with the barkeeps.
They poured great Irish Coffes, clean warm glass with every drink. No well booze allowed with this one drink. 
He’s Vietnamese.
