Hello Guys
1st Issue
I have a GCP with a Eureka Mignon Crono which has a 50mm burrs.
The coffee tastes good, but I never reached 25-30 seconds of extraction, the closest is 18 seconds.
I add 9g of beans into my grinder and I get 25-30g in my cup, I always use the single basket.
Can you direct me with troubleshooting steps ?
2nd Issue
My final goal is to make cortado, I tried couple times after reading guides and watching videos to steam milk, but I can’t steam like they do.
I use 3% milk, Any tips?
First off, if the coffee tastes good, you don’t need to worry about hitting a certain time just to do it. But if you do want to:
I don’t have this kind of machine, but I know that most folks say that single baskets are inherently difficult to work with, and you should just a double instead. That’s not to say you shouldn’t use the single, but maybe look for some single-basket tutorials that might have specific advice?

In terms of slowing down your shots, other than grinding finer, you can also increase your dose within a given basket.
Also, if your GCP is stock, then it might be worth doing the overpressure valve mod. By default, those machines have a really high pump pressure, and replacing OPV spring with a 9 bar or lower one is a very common mod for the GCP.
