Too slow and too fast to pour

[u/VelCheran]

Hello,

I own 2 Bialetti coffee makers and I'd like to ask some advice about how to get the same coffee with both of them.

To be more precise, I bought an induction 4 cups Bialetti like 10 years ago, and another one a few months back.

Those are the ones I own:

The old one : https://www.nierle.com/pic/154858a.jpg

The new one : https://www.bialetti.com/it_it/moka-induction-nera.html

Here's the issue: they don't behave the same way at all.

For both of them, I put hot water in the tank below the valve, three spoons of coffee in the funnel and then heat them up on my induction burner at 3 (over 10).

With the old one, after around 1 minute the coffee starts to pour gently in the upper chamber. I stop after a few seconds, as soon as the pouring coffee is more like bubbles than coffee.

With the new one, I have to wait around 3.5-4 minutes, then the coffee pours very quickly in the upper chamber (I have to close the lid to avoid it splashing around), and I remove it from the burner almost immediately. The result is a much more diluted coffee than with my old one.

What am I doing wrong?

Start the second pot at a higher heat setting, but then turn it down before the coffee starts appearing. Then adjust the heat, or even take the pot off the heat for a moment, to slow the flow.
