The American found a closed bottle of Soviet Pepsi-Cola in his father's bedroom and posted the picture on reddit. The label has faded, but you can still see the inscriptions in Russian on it and the price without the cost of dishes (31 kopecks!). It was this Pepsi-Cola that was sold in the USSR in the 1980s.
As it turned out, at that time my father worked for Pepsi. He decided to keep a bottle of Soviet soda as a keepsake. So she stood in the bedroom until the author of the post found her.
The American decided to take a chance: he opened the bottle and took a sip of Pepsi (presumably) 40 years old. Of course, nothing good came of this. “Tastes like steel and plutonium,” said the author. And he noted that the stomach may not approve of his recklessness. "Expecting a Cuban Missile Crisis," he wrote.
