Let's talk about the American style of two brothers, one is Long Black and the other is Lungo, they drink American style is a mixture of espresso and water, so what's the difference?

Americano is to add espresso first and then water.

For Long Black, water is added first and then Espresso is extracted.

Lungo is to speed up the flow rate of espresso by changing the scale of the grinder without adding extra water.

So what is the difference in taste brought about by different practices?

The grease (crema) on Americano will be washed away by hot water. As the grease on the Long Black is poured later, more grease will be seen on the surface of the coffee, and the grease will last longer because it does not receive external force. The insoluble substances in oil (crema) are the result of emulsification under high pressure. And the oil contains carbon dioxide, containing a lot of flavor and aroma. At the same time, because of its insoluble ingredients, this layer of oil forms a film on the coating of our tongue when drinking it. This film will give us a lasting aftertaste while weakening the sensitivity to bitterness. So Americano will be a little more painful than Long Black.

Let's take a look at Lungo. Lungo is very popular in Italy. Only about 60ml. The decrease in the amount of water brings a fuller taste. In English, Lungo means Long, and Lungo actually means Espresso that lengthens the extraction time. However, visit many domestic cafes, it is almost rare to provide Lungo coffee shop, probably the production also requires an independent bean grinder increased a lot of complexity, we have to combine practice and relevant materials to make, we adjust the parameters, lengthen the extraction time found that Lungo oil is the most stable of the three, taste lighter than Espresso, but at the same time will be a little bitter. Compared with Americano, it tastes more mellow, while Americano may be more bitter.
