I did not know about bottomless portafilters - they look cool!

<p>I have a manual espresso machine. I have to turn the pump on and off with a switch and judge when to stop by myself.</p>

<p>How do I judge when the best point is to stop pulling the shot? Do I do it by volume, colour, or something else?</p>

Specifically, what kind of a machine do you have? Or even more specifically, what machine do you have? I've only used [this kind](http://coffeegeek.com/guides/howtobuyanespressomachine/manualmachines) of machine, which has a mechanical lever (you say pump and switch...), and you control how much water ahead of the pull by how much you raise (or pre-cock) the lever. That link also discusses some other factors besides volume and time.

# How do I know when to stop pulling my shot?

(Asked by: username_0 on 2015-02-10)

I have a manual espresso machine. I have to turn the pump on and off with a switch and judge when to stop by myself.

How do I judge when the best point is to stop pulling the shot? Do I do it by volume, colour, or something else?

Assuming the perfect grind, you are looking for extraction time and volume.

The ideal double shot should be **60 mL** (about 2 US fluid ounces) and should be extracted between **20-30 seconds**.

I use the double shot as the example because it is considered to be the standard.

So essentially, pull a double shot until 60 mL or 2 ounces comes out. You can use something to measure this volume like a graduated shot glass. Time how long this takes. I always aim for 20 seconds. If it is faster than 20 seconds, then you need to make your grind slightly finer. If it is slower than this, then you need to make the grind slightly coarser.

Then modify to your taste! If you like the way it tastes when it takes 30 seconds, then drink away and enjoy. If you prefer 20 seconds, then enjoy that!

Half these values for a single shot.

**Note:** Some people will argue that a double shot should be 40 mL and not 60 mL. This is also about preference.
