Although the Massachusetts-based brand Chemex can’t compete with multinational giants like Samsung or Bosch, it has managed to gain a fair share of the market due to its narrow specialization. It manufactures so-called Chemex coffee makers, simple pour-over style glass-containers invented in 1941. Although originally, the range consisted of only manual coffee makers, today the company also manufactures automatic machines capable of brewing both hot and iced coffee.
