When the Venetians brought coffee to continental Europe, coffee was popular with the local people. But the business in the wine and beer industries was falling in Europe. However, these traditional catering industries have bribed the pharmaceutical trade unions, objecting to the excitement and stimulating effects of coffee, but several verifications have failed to prove that coffee has any side effects.
At that time, the secret slogan on the coffee table was to overthrow the autocratic monarchy and establish a republican government. Especially when college students mentioned democracy and participation in politics, they were even more heated and bold.
The coffee valve heard that the ruler at the time was very angry and asked to ban a series of coffee-related matters,even the newspapers in the cafes are hard to escape.
One way valve believes that drinking coffee should be like tasting wine, first smell the aroma, and then try a small bite, that you can taste the essence of it.
