Does pre-infusion reduce channeling?

In practice, this works quite well. When we’ve tested shots pulled with pre-infusion vs shots pulled without we notice significantly fewer instances of channeling – that’s when water finds a path of low resistance and flows through it, avoiding nearby grounds.

Should extraction time include pre-infusion?

As long as your pre-infusion time is always supposed to be 7 seconds then it shouldn’t be a problem. If the pre-infusion times are off it means something needs to be resolved and you wouldn’t notice this if you’re not tracking time.

What is coffee infusion?

Infused coffee is the process of extracting flavors from coffee grounds, similar to steeping tea leaves. The traditional method of “pressing” (with a plunger) has the potential to result in over steeping the grounds.

Does pre-infusion count?

When should you shot espresso?

The ideal brewing time you’re looking for is between 20 – 30 seconds – if you’re running too long or too short, check your grind, dose and tamp, then adjust it accordingly. If your shots are coming out unevenly from both spouts, your tamp needs to be more even.

How does pre-infusion work?

Pre-infusion refers to the process of gently soaking the puck of ground coffee in your portafilter before applying the full desired brewing pressure. The goal is to ensure that water evenly penetrates the grounds to ensure that the entire bed has the same amount of water flowing through it once extraction begins.

How do you increase espresso extraction time?

As you grind finer and finer, it will take longer and longer to reach your desired yield. For a while, this will result in increased extraction and strength. Eventually, you’ll reach a point where the extraction and strength move backwards. It’s like a law of diminishing returns for espresso grind size.
