My espresso only tastes good when everything says it shouldn’t
I could really use some advice because I’m completely confused at this point.
My setup:
La Marzocco Linea Micra
La Marzocco Pico grinder
19grams “Wild at Heart” beans (around 2 weeks off roast)
Volvic water
I’ve been trying to dial these beans in for days.
I started with the recipe from the 19grams website:
19g in
1:2 ratio
around 30-35 seconds
93-94°C
The shots were consistently bitter, heavy and almost tasted burnt.
I contacted 19grams directly, and they told me they often use this recipe in their cafés instead:
17g in
34g out
around 35 seconds
94°C
So I tried that as well.
Over the last few days I’ve probably pulled dozens of shots using:
17g, 18g and 19g doses
different ratios
temperatures between 92°C and 94°C
lots of different grind settings
No matter what I did, the espresso always tasted more bitter and roasted than I expected.
After what felt like my thousandth attempt, I thought: forget the numbers. I’ll try something completely extreme.
I ground much finer than before.
The shot took about one minute, and I only got around 9g out from a 17g dose.
I know that’s nowhere close to a normal recipe.
But here’s the strange part…
It was the first espresso that I actually enjoyed.
It suddenly became much sweeter, with clear strawberry notes, and almost no bitterness.
Since then I’ve gradually opened the grind again. As the shot gets faster and the yield increases, the bitterness slowly comes back.
Now I’m completely confused.
Everything I’ve learned says that a one-minute shot with only 9g out should be massively over-extracted and probably taste terrible.
Instead, it was by far the best shot I’ve had with these beans.
So my questions are:
Has anyone experienced something similar?
Would you ignore shot time and simply dial in by taste?
Could something be wrong with my grinder calibration?
Does anyone here use Wild at Heart on a Micra/Pico and have a recipe that actually works?
I’m still pretty new to espresso, so I’m trying to understand what’s happening instead of just chasing numbers.
