请教咖啡问题

cxiaoga

早起去打猎, 滑雪, 玩帆板, 去机场, 在加油站买一杯咖啡, 浓郁的咖啡香吣人心脾, 马上驱除了倦意. 可在家, 在公司喝的咖啡却没有这股浓香. 我试着用咖啡豆现磨现做, 也不行. 这里有什么讲究吗?  还是咖啡豆本身不够香?  或者我那时正需要咖啡, 所以觉得香?  谢!

Because of the water temperature. The hot water from coffee machine is under high pressure and its temperature is above 100 C-deg (212 F-deg). The water temperature from your regular pot at home is not hot enough to "burn" the coffee. In this way, the coffee does not evaporate its smell. However, coffin is still in there, which is still good to wake u up.

120 - 140 C-deg is desirable. U might see some coffee shops applying "steam guns", instead of coffee machine dropping water.

Thanks for explaining, Jerrybj.  That makes sense.  Do you mean to use steam espresso machine for brewing coffee?

Steam machine: It is a large rectangular box, which generates steam, has a hose with a nozzle. When u order coffee, it puts coffee bin in a small scoop. Then grind it. Then apply the steam thru the nozzle to the coffee in one shot only.

In European countries, above all in Paris, it is a very popular one. But it is rarely seen in North America. One of the differences is French have coffee for its taste only. People here, including me, have coffee when we are thirsty. So we always have large cups. But French have tiny cups. U cannot have a large quantity steam.

Quite a few yrs ago, an aged woman bought a cup of coffee by drive-thru from McDonald restaurant. Then she had the hot coffee on her leg and got burned. She won more than $10 million from McDonald. McDonald would rather pay millions dollars without revealing its coffee temperature and refused to lower the temperature. All of us like to have McDonald's coffee for breakfast.

Thanks everybody for the inputs.  It seems that I need to do more homework on that like beer brewery.  By the way, that picture of coffee machine is too fancy.  It must come from lab.

哈哈，那才是咖啡之道。有机会试一下，同样的豆子，咖啡机器出来的味道单调了很多。。当然前提是手工制作控制的好，搅拌，水温，时间，沸腾，甚至搅拌的方向都come into play.

你也太雅了!  这syphon coffee brewer (vaccum coffee maker)又是要94-96度水, 又是要酒精炉, 只有你这种追求纯粹的雅人才会享受得了这20世纪初的咖啡道.
