COFFEE QUESTION

Dear HIW,

How are coffee beans turned into instant coffee? Stefan Lewis

Thanks for your question Stefan. Most of the coffee you have come across is likely to be instant coffee, as around half of all harvested coffee is made into instant coffee. First, coffee beans are cleaned and roasted at 230 degrees Celsius. When they are cool again, the beans are ground, with any lost aromas pumped with nitrogen into a tank. Next, the coffee is brewed and evaporated so that thick coffee syrup remains. When this syrup is frozen and broken into granules, all there is left to do is store them in low pressure for several hours and spray the lost aromas onto them to produce instant coffee.

To make coffee using instant coffee, you just need to add boiling water
