A brief history

This refreshing cold drink has won the hearts of many coffee lovers in recent years. It is one of the most recent coffee preparations, and has become very popular in the most famous venues in the world, particularly in the USA and England. In actual fact, its rather mysterious origins date back many hundreds of years: it seems that people in Kyoto in the seventeenth century were already enjoying a coffee made through cold preparation. The technique was probably brought to japan by Dutch merchants, who passed through the country on their long trading journeys.
