Cristal

Cristal is the brand name of a Champagne produced by Louis Roederer. Cristal has a flat-bottomed clear, "crystal" bottle, anti-UV cellophane wrapper, and gold label. Due to its high price and status, it is considered a Veblen good
Cristal was first created in 1876 for Alexander II of Russia, and is viewed by many as the first prestige cuvée. As the political situation in Russia at the time of his rule was unstable, the tsar feared assassination. He ordered that bottles containing the drink be made clear to prohibit hiding a bomb within them, as could happen with a typical dark green bottle.[citation needed] Louis Roederer commissioned a Flemish glassmaker to create a Champagne bottle with a flat bottom. Typically, bottles made from common glass have a bell-shaped bottom (the punt) to make them strong enough to cope with Champagne's pressure. A flat-bottomed bottle needed to be made from stronger, clear lead crystal. The Champagne has since become known as "Cristal".
The wine was not commercially available until 1945. In the late 1990s and early 2000s, the brand became increasingly associated with rap and hip-hop culture, with several artists referencing the drink in song lyrics and as part of their public image. In an interview with The Economist in 2006, Louis Roederer managing director Frederic Rouzaud said he viewed the attention from rappers with “curiosity and serenity”. Asked if he thought the association would harm the brand, he replied, "that's a good question, but what can we do? We can't forbid people from buying it. I'm sure Dom Pérignon or Krug would be delighted to have their business."
