One Way Valve Hand Drip Coffee

Today one way valve went to a cafe and ordered a cup of coffee. There were not many guests in the shop. The barista was a friend of mine. On a whim, he said he would teach me how to make a cup of coffee.

I see he did feel quite simple, the coffee from the coffee bag with valve removed and ground into coffee powder, and then placed in the filter paper and then to pave the way, which inject warm water to its extraction trickling filter is completed, a rich aroma of coffee is ready. So I said: "well, looking at it very simple, it should not be difficult!"

Then give me coffee materials and appliances are ready, let me try. I think he just do the process, step by step in his process again. But it is very strange that he had injected in warm water, coffee powder will expand, forming a mushroom however, when I did not. When I ask questions, he told me: "water when you turn around, and the speed should be uniform, not when the fast slowly." although I understand, but it is not so simple, like the hand always refuses to write, very difficult to do he said.

Soon, coffee is done. I drank a cup of taste, feel a lot worse, then put forward some questions, I said: 'it seems very simple steps, how to do it will taste difference so much?'he smiled and said: "I did so many years is not a waste of time".
