### Instruction: What's the best way to brew an espresso?
### Response: There is no general consensus on how to evaluate a cup of espresso, so there is no general "best way". Here are a few pointers that most of the coffee-lover community agrees will enhance the consistency and flavor of an espresso:

* Use freshly roasted beans! No amount of expensive espresso machines can save a stale batch of beans.
* Make sure your puck is evenly distributed. If needed, use a WDT tool to stir the puck gently from bottom to top, until you reach consistency.
* Observe the brewing process closely and make sure the fluid flows smoothly. If the stream is unbalanced or side-splitting, check your puck and your machine's pressurization.
