所以新的机器都是15帕，压力系统更新换代了

很多改装套件都是改回9帕的

Z80CPU

还是自动的好。除非你是咖啡达人。

压力越大越容易坏。

压力越大越容易坏。

有压力阀，超过压力会停下。这种贵的机器，会有一些保护功能。如果你粉压太紧，咖啡机是不会硬打的。

专门买了能调成9帕的。

这个机型至少卖了15年了，压力是9帕。
新式的机器都是15帕，你可以在功能介绍里面找到。
压力当然是越大越 ...

萃取基本上都是9帕，又不是轧钢，越大越好，新机器都是15帕？好像没听说。

Domestic machines are a lot smaller and cheaper than the professional espresso machines. So while the machine may have 15-bar of pressure at the pump, by the time the water reaches the brew head this is significantly lower. If the machine is setup correctly the brew head pressure will be around the perfect 9-bar mark, regardless of what pressure the pump creates.

Some of the more advanced machines have OPVs (overpressure valves). Look for these in a machine’s spec sheet. OPVs regulate the pressure of a machine. When the pressure is under 9-bar, the valve will not open. When the pressure is over 9-bar the valve will open and let the water escape, resulting in a steady water stream of 9-bar.

这个不太认同，压力并不是越大越好，现在主流的认知还是9pa

不好意思楼主，我歪楼了。
我手上在用德龙的la specialista。这是第三台了。
第一台是sunbeam，新手机，价格便宜，该有的功能都有，钢琴烤漆的，很漂亮。 15bar，用了6年坏掉了，没有压力阀，出咖啡的地方开始漏了。
第二台是breville，要等预热，烦，送朋友了。
第三台是比较新的德龙，糟点也是很多。最困扰我的是打奶泡的杆子，要拆开洗，装不好奶泡出的少。压粉一体式，就是压很多次都压不结实，打咖啡到不了最佳压力。

What is the best BAR pressure for a coffee machine?
One of the best BAR pressures for a coffee machines is 9 BARs. Some claim that 7-8 BARs is even better. Why? Anywhere between 7 to 9 BARs is optimal for a perfect espresso extraction, leading to rich, tasty, balanced and creamy beverage.

If you want ‘crema’ on top of your coffee, or a flavorful, aromatic golden cream that sits on a freshly brewed cup of espresso, then pressure should be of particular interest. Only an espresso maker capable of yielding between 7 to 9 BARs can deliver it.

根据你说的判断你应该用的是德龙的La specialista吧，问题不是出在压粉压力不够，而是因为机器的grinder可以调节的范围太少，磨出来的粉不够，所以压力上不去。不过我记得德龙用的是double wall的basket，应该可以憋住压力啊。

粉够细了，压的不够紧，要压个十几次，粉不能多。还要低于指导线，这个一体式的设计是个Bug……
