At first, coffee was expensive in Europe. Only aristocrats could drink coffee, and coffee was even called "black gold". Until 1690, a Dutch captain sailed to Yemen and got some coffee seedlings, which were successfully planted in Indonesia. In 1727, the wife of a diplomat in Dutch Guiana gave some coffee seeds to a Spaniard in Brazil, where he planted them with good results. The climate in Brazil is very suitable for coffee growth, and coffee has spread rapidly in South America since then. Coffee, which has fallen in price due to mass production, has become an important drink for Europeans.
Through the coffee machine temperature and pressure measuring instrument, we check the temperature and pressure of each machine to ensure that the temperature and pressure do not affect the experimental results, the temperature and pressure test results are shown in the table below.
In order to ensure the consistency and reliability of coffee taste, three coffee experts formed a jury.
In order to make the test results more fair, the same expert was designated to extract coffee and make cappuccino in this test. The coffee used in the experiment was a unified Italian blend of coffee beans, and the experimental time was the 22nd day after baking.
