Germans spend over $4 billion euros a year to buy their favorite morning drink: coffee. A new study by the market research firm Nielsen published Sunday, showed that Germans spent this sum on buying coffee in its different kinds from shops from early December 2017 till early December 2018. In 2018, Germans bought a slightly lower amount of coffee than in the previous year, with figures falling to 382 million kilograms, 8 percent less than a year earlier, the study noted. But market researchers see this drop doesnt necessarily mean a decline in Germans consumption of coffee, according to the German news agency. "According to our assessment, it could be because Germans drink coffee frequently outside home," said a beverage expert at Nielsen.
