Champagne is notorious for its bubbles.
These bubbles arise when dissolved CO2 in the liquid reacts with condensation nucleii - in other words, contamination - on the surface of the receptacle.
As a consequence, the champagne goes flat, losing some of its attraction.
But now, BorgCo Services
can clean your champagne flutes with hydrofluoric acid, giving a superclean interior surface*. When champagne is poured into a glass so cleaned, it will not fizz; that effect is delayed until it enters the consumer's mouth, giving a superior quality of experience.
*For a very modest additional charge, BorgCo will ensure that all traces of HF are removed from the glass before returning it to the owner.

High Freq Sound Cleaning

Works quite well, obliterates problem entirely. [whatrock, Aug 20 2016]

My recollection is that HF will etch glass. Using it to clean glass should result in millions of tiny etched imperfections. The end result will be the same as pouring the champagne into a glass made of Mentos. |
|
| |
Which would be a fine prank. |

Somebody has just been watching the QI repeat. We
see everything, you know. |
|
| |
Incidentally, this will not work, as the esteemed
[bungston] has just pointed out. |
|
| |
Isn't a flute without imperfections impossible due to the very state nature of glass and the shape wanted? |
|

A vessel with a powerful hydrophobic coating would have a lovely silvery look but would probably go flat quicky. |
|
| |
I would suggest plasma cleaning, as is sometimes used to clean microscope slides. The surface becomes hydrophilic, I'm not sure what effect that would have on nucleation. |

Anyone see where that glass went ? |
|
| |
Not "plasma" in "plasma directed-energy weapon", then ? |

Use high-frequency sound instead and you don't even have
to change the title. |
|
| |
Well, yes, but no Proper Bloke would EVER use mere high-frequency sound when there was Hydrofluoric Acid burning a hole in its bottle ... |
|

The solution, shirley, is to take a spare bottle of Krug
up to the ISS and let them pour a gob out in
microgravity. |
|
| |
Actually, that would be a pretty cool experiment to
do. |
|
| |
Why not just drink the Hydroflouric? If you do that first, you won't ever have to worry about your champange being short of a few bubbles again. Hydroflouric Acid must be one of THE nastiest liquids on the planet. |

Shortly behind fermented soy and marmite. |

And Foster's "lager"*, a beverage** so foul that even a scotchman*** won't drink it out of choice****. |

***The de-facto SI unit of barbarism. |

****But will, nonetheless, still drink it in an emergency i.e. all the methylated spirit, metal polish and brake fluid has already gone. |
|
| |
That's strange, [8th], because Fosters is actually
produced by Scotchmen. Of course, getting them to
hit the opening in the top of the can is difficult. |

My guess is, in space, the whole globule surface becomes the open suface. Globule wobble agitates internally dissolved gas which accumulates and bounces it's way to pop through the surface. But I would still like to see it. Maybe the experiment should be done in a sandbox to save on environmental cleanup. |
|
| |
I thought you could just mechanically machine and polish
the inside - down to microscope lens finish. |

At Panera Bread they have this wonderful sprayer
wssher thingy which cinsists of a vertical column
that sticks up from the middle of the sink. You
place a bowl or cup or mixer ot glass over it, press
down on the ring a little, and it spray washes the
object surrounding it. Brilliantly simple. |

At least Scotland had the good sense to vote
Bremain. |

Yeah, there's some variations on that tool for homebrewers, but my wash five hundred bottles days are over. |
