Coffee has always been the most expensive commodity, with its price set by the number of kilograms of it that can be sold per year.

The coffee market is set to reach a record $2.8 trillion by 2031, according to the World Bank, and is expected to be the main driver of global inflation over the next 10 years.

Spice, on the other hand, is expected in 2019 to reach $2 trillion, according the World Economic Forum, a group that advocates for a more balanced global economy.

In the past decade, coffee has been a favorite among the young, who like the feeling of coffee and the taste of spice.

A study in the Journal of Agricultural and Food Chemistry found that people with a taste for coffee are more likely to spend money on food than people with an aversion to spice.
