Dačický is a brand of pilsner-type beer made by Drinks Union in Kutná Hora, Czech Republic. It was first brewed in 1573. It was sold to Heineken and is now produced in Grand March near Usti Nad Labem along with some other brands purchased by Heineken.
Dačický was first brewed less than 100 years ago.
It's definitely incorrect because it was first brewed in 1573 which is well more than 100 years ago. I think it's difficult because the system is not good at comparing dates in the past to the current date to answer these types of questions.
