In the
Star Trek universe, in order to constantly remind the viewer that the show takes place in
The Future, even the everyday items had to look somewhat odd and otherworldly. A typical example is the barware and glassware.
There is a bottle first seen in "Charlie X" in the Recreation Room as Janice Rand is playing cards and Lieutenant Uhura sings. It is seen on a serving tray with a couple of martini glasses and a bottle of Saurian brandy:

The bottle is somewhat squat looking but what makes it look particularly odd is that it appears to be a bit crooked and melted-looking. It's a bit hard to see, but the same bottle gets another appearance in "Dagger of the Mind." Dr. Tristan Adams pours a glass of--something--Aldebaran whisky?--for himself, Captain Kirk, and Dr. Helen Noel. He pours it from this same crooked, melted-looking bottle:

We see the bottle briefly again in "Journey to Babel." You can see it at the reception for all the ambassadors and diplomats; it's 'way over at screen-right:
The bottle shows up a fourth time--in Mr. Scott's quarters in "By Any Other Name." Mr. Scott attempts to get Tomar the Kelvan drunk--and the two of them partake from this same bottle. This is probably the best look we get at the bottle:

The bottle shows up a fifth time--in the quarters of The Romulan Commander in "The Enterprise Incident:"

Lastly, it shows up again in "Let That Be Your Last Battlefield." Captain Kirk, Mister Spock, and Commissioner Bele are enjoying some drinks. You can see the bottle over on the credenza--along with some serving trays and a Saurian brandy bottle:

These are known as "Kluk Kluk" decanters (in Danish) or "Cluck Cluck" in English. The name of the bottle comes from the sound these odd-shaped bottles make when you pour from them. It's sort of like a "glug glug" sound from a jug, but higher pitched.
The original, classic version of this bottle is made by Holmesgaard glass company in Denmark; it was designed by the glass artist Per Lutken. (Over the years, other companies have made knock-off versions.)
Here are a couple of shots of my vintage 1960's-era "Kluk Kluk" decanter filled with Aldebaran whisky or whatever it was.




Not much of a story here. Just a really cool exotic-looking bottle.
