Channeling is one of the most common challenges when extracting an espresso, but the truth is that this problem usually starts before the extraction.
If you want to improve the consistency of your shots, here are the two main aspects to focus on:
1. Coffee Distribution
The first thing to check is the coffee distribution inside the basket.
- If the coffee bed is not even, the water will always find the easiest path.
- A helpful solution is definitely using a puck diffuser.
- It’s important to remember that this tool doesn’t fix a bad recipe.
- However, it helps to make a good preparation more stable by spreading the first contact of water more evenly on the coffee bed.
2. Water Delivery
The second crucial step is how the water reaches the puck, and this is where the shower screen comes in.
- A shower screen with an integrated membrane and nanotech coating spreads the water more evenly.
- This system reduces concentrated water jets and improves consistency shot after shot.
- Let’s debunk a myth: the shower screen doesn’t change the machine pressure.
- Instead, it changes how the water flow is distributed on the coffee puck.
