Haven’t really used a mocha pot before, so I’m experimenting a little to find the right grind settings and ratios for my taste. Normally brew espresso on a flair classic. Went with this more modern design from bialetti because it also works on induction stoves.
To avoid getting coffee grind in it, we tend to use somewhat courser grinds when making mocha. Recently there was a study that adding a tiny splash of water prior to grinding unlocks the most flavour, so there’s that as well.
We are still not sure if it is better to slowly heat it from cold water or to just put it on the hottest and have it done faster. As I was typing this, I did a quick search and some guy on reddit even has the water boiling first, before assembling it. I suppose it doesn’t matter all that much, as long as the grind size is not too small.
That being said, I’m hardly an expert, but I do enjoy a good mocha coffee from time to time (I think I will have one now, actually).
I always spritz my beans prior to grinding, but mostly to keep the grounds from sticking to my grinder. Didn’t known it also had an impact on extraction.
The primary reason for me to get this was to have a simpler workflow for a quick cup of coffee than my flair, so I’ve only been using it with cold water in from the start. It works pretty well I would say.
James Hoffman (youtube coffee expert) advices to put hot water in the cup because it gives a less acidic coffee. https://youtu.be/BfDLoIvb0w4
I’m using my moka pot on an induction stove that goes from 1 to 9, and there’s also a P setting for max power. Normally, I just use P or 9 to make the water boiling hot. Then I leave it at zero and assmble the whole pot. After that, I set it to 2, and wait. Letting the water cool down just a little at zero heat is important. If you keep the stove at 2 while assembling the moka pot, you’ll get the water flowing way too fast, and you’ll get under extracted weak coffee.
There’s a reason for doing it this way. If you heat the water with number 2 power, it’s going to take way too long. If you give it more heat, it will obviously heat up faster, but it will also increase the flow way too much. On top of that, you’ll also get steam running through the grinds, and that tends to bring out all the bitter notes very quickly. Therefore, doing the extraction at the lowest heat possible is the way to go. Since the moka pot doesn’t have a pressure gauge, it’s very difficult to tell when would be the ideal time to reduce the power. In order to avoid that problem, I recommend boiling the water before assembly.
