I specify at home, since if you really want a taste of the real thing, there's nothing like a real espresso at the bar - and mind you not every bar - best I have ever had so far being St Eustachio in Rome, a legend that lives up to its name.
As you know, in Italy having an espresso is not a social thing. The whole experience lasts 2-3 minutes with probably 30 seconds spent enjoying the espresso - one of the reasons in Italy the expression 'let's go for a coffee' is almost like saying goodbye ;)
Back to espresso at home. Obviously the starting point is ... the coffee itself. A necessary but not sufficient condition, as mathematicians would say. Good italian coffee brands are readily available in many stores these days, my favourite ones being Kimbo, Illy and Lavazza Qualita' Rossa.
With a good coffee mix you are about 50% there. The rest is in the coffee machine, and the way you prepare it to some extent.
I'm not going to consider home versions of professional coffee machines - some of them are actually pretty good, but they fall into the category of 'substitute' of the real bar experience.
Let's instead talk about Moka espresso. A tradition that probably goes back thousands of years, even before the bar coffee machines were created. Moka espresso is its own thing, and if made properly can be a truly enjoyable experience.
I can safely say that when it comes to choosing a Moka, there's really no choice other than the Bialetti moka.
That's a true classic, unchanged for decades and even without any data I can say that there's probably at least one Bialetti moka in every Italian home, in and out of Italy.
What's not as well known is that there are probably not two Mokas that are identical...because their life is different. Two mokas are like two identical twins, who may have completely different life experiences and end up with quite distinct personalities.
There's something scientific and magical at the same time in the way coffee interacts with the Moka's metal and bonds in a certain way to change its characteristics over time, deeply impacting the taste of the espresso.
Therefore, rule number one - and possibly the only rule - is to love your Moka and take good care of it as something that will keep improve over time and you will eventually pass it from generation to generation.
Here's how you do that:
- Once you buy your Moka, 'burn it in' by making at least 4-5 rounds of coffee which you ...sigh..can probably want to throw away because it really won't taste good. It will probably require at least 100 cycles before you can start tasting a glimpse of the real flavour.
- Never wash it with soap. Just rinse it gently with water and make it dry by leaving it disassembled on a cloth. Residues of coffee will accumulate in the chamber and start the ..transformation process.
- Use it frequently. Daily use is recommended, and remember that if you let is stay idle for over a week you'll have to do another quick burn-in cycle depending on the length of the period.
Now to the actual making of the coffee. The procedure is very simple: you first fill the bottom part with water (I use brita-filtered water - calcium is not good for the taste and for the Moka) until just above the exhaust valve level. Put the coffee in the container without pressing it, making a little 'mountain' that raises a couple of CMs from the edge. Screw in the top part of the Moka.
Temperature level is important. In my Bertazzoni stove I have a special burner for coffee, which is small enough so that the flame stays below the Moka. If you don't have that, just use a flame reducer.
For electric stoves, you may have to put the Moka at the edge of the burner to avoid melting the plastic handle...
Burner temperature must be relatively low, say 1/4 of full power. In about 5 minutes, the Moka will start making the characteristic 'bubbling' noise and coffee will start coming out from the small hole at the top.
Here's where you will know if the temperature is right: if it's the right temperature, the coffee will come out with a steady flow without sputtering, so that you could potentially keep the lid open (not recommended) without making a mess all around.
Once all the coffee has come out and you only see bubbles being expelled, turn off the gas and serve immediately.
Pre-heating the cups is very important so that the coffee does not cool down immediately (you can put hot water in them, remove it and dry the cups with a cloth).
Lots of people drink coffee 'black' with no sugar, I tend to put a spoon of sugar at the bottom of the cup before pouring the coffee, and then stir quickly to produce a bit of foam.
Enjoy your espresso,
M
