<p>Conversely, if the coffee beans you are using are very old, there will be no crema over your shot, which is also not a good sign.</p>
<p>There are also some other factors that make the shot too foamy. Read <a href="https://coffeeabout.com/why-is-my-espresso-foamy/" target="_blank" rel="noopener">this article</a>, it might help you.</p>

More info is needed. What's the coffee? Is it a fresh crop? What is the roasting style? Do other coffees from the same company exhibit a similar effect in the portafilter?

When this happens, is it a random shot after seeing several "normal" extractions, or is it the whole bag?

Jason,<br />
<br />
I meant to ask what roaster you were working with? Do they offer training? Sometimes the better roasters will have guidelines or brewing suggestions/parameters for their espresso. Have you asked them?<br />
<br />
Also, dropping the dose a hair and grinding a bit finer will sometimes help when the espresso is fresh or you're getting what you are describing here.

I worked at a shop where the sweet spot for the espresso was 10-14 days out...9 days and it was still really foamy, 15 days and there was hardly any crema to be seen. It was strange, but once we stretched out and tried things that we wouldn't think of to begin with (aging 10 days for instance), it really started to come alive.

<p>It's pretty big bubbles I'd say. It add's quite the volume in the cup and looks like a a large foam head like a beer! We're still playing with it but we haven't gotten a very good flavor out of it either...<br></br> <br></br> <cite>Phil Roberts said:…</cite></p>

<p>Is the extra "foamy" big bubbles or small, fine bubbles? Big bubbles generally means it may be too fresh. Fine bubbles generally means great extraction. How does it taste? I know you mentioned the espresso is 7 days out of the roaster, and should be well rested by then (typically). </p>
<p> </p>
<p>Some espresso (like hairbender) may always be extra "foamy" even when 8 days out. I have also seen it be rather small, tight bubbles on the same day out, using the same technique, but on a different machine.</p>
<p> </p>
<p>Maybe someone has better insight, it may be water quality, pressure difference, or something. Hope you get some good responses!</p>
