ネスカフェ

Nescafé's introduction significantly increased coffee consumption and created new coffee fans, particularly during and after World War II.
U.S. per capita coffee consumption actually peaked in 1946 at 46.4 gallons per person - right after the war when Nescafé had become widely popular. During World War II, Nescafé's sales volumes doubled, showing rapid growth in popularity.

Nestlé chemist Dr. Max Morgenthaler worked for seven years to develop a soluble instant coffee that would preserve coffee's natural flavor and aroma. 
The challenge was to create a product that could be easily prepared by simply adding water while maintaining the quality of real coffee.
On April 1, 1938, Nescafé was officially launched in Switzerland.
