Better yet, manual
It is believed that alternative brewing methods, which include aeropress, require a unimodal grind - that is, a grind in which the size of the coffee particles will be closest to each other. Such a grinding can only be achieved by coffee grinders with flat millstones (and even then, by no means all), and I have never seen such manual coffee grinders.
In addition, the speed and
uniformity the rotation of the millstones also affects the result. For example, in the top-end manual espresso grinder (there are conical burrs from Mazzer Robur - they give a bimodal grind) HG one
hg-one. com / the-hg-one-grinder /
The manufacturer has made a large flywheel and separately indicates that it is important to rotate the handle evenly.
As a result, it turns out that an electric coffee grinder with a flat burr would be better for an airport press. So far I have bought a Mazzer Major for Grocery with 83mm flat burrs: although it gives a noticeably bimodal grind, it will not contain as much fine "dust" as in any conical grinder.
On the other hand, for espresso, where bimodal grinding is more important, your recommendation may well be relevant.
with ceramic millstones so that the grain does not burn.
Ceramic / steel millstones have nothing to do with overheating of grains: overheating does not depend on this. And moreover, all other things being equal, the ceramic will heat the grain a little more, since:
- Ceramics cannot be as sharp as tool steel;
- The thermal conductivity of ceramics is noticeably lower than that of steel.
But all this is not very important, since the turnover plays a noticeably large role.
As a link to an authoritative source, I would like to cite the data of such a manufacturer of coffee grinders (and OEM grinders for other manufacturers), such as Ditting Maschinen AG:

1. Are Steel or Ceramic burrs better?
This question cannot be answered in general. Each material does have its advantages. Steel: Really precise adjustment and grind size is possible. The burrs are break resistant. Number and geometry can be changed. Ceramic: Have a longer lifetime. Are less expensive than steel grinding discs. Form / geometry is fixed. Ditting also offers ground ceramic discs.
2. Which Grinding burrs have the longest lifetime?
In General, Ceramic burrs have a longer lifetime than steel grinding burrs. Additionally, the bigger the diameter of the burr (Ditting offers diameter from 54mm to 180mm) the longer it last. Burrs with more than 80mm can be re-sharpened, which is less expensive than replacing the burr by a new one.
3. Which diameter (54mm - 180mm) is the right one for me / the best one?
This depends on the grinder you use. Each grinder is engineered for a special diameter, that is not changeable. In the OEM-business we only use 54mm, 64mm and 65mm grinding discs. If you haven’t decided on a specific grinder yet, the rule is that the bigger the diameter of the grinding discs, the lower the temperature of ground coffee - that means more gentle grinding. Also the performance increases with bigger grinding discs but also the motors need to be bigger and the grind-er will be more expensive.
Bottom line: if you are worried about overheating, then the grinder should have millstones with a large diameter and low revolutions. Ceramic millstones are cheaper, have a longer resource, but are more fragile than steel ones.
Further, if we go to specific examples, then I would like to draw your attention to two coffee grinders, Baratza Forte AP and BG:
baratza. com / choosing-your-grinder /
The first has ceramic burrs and is more suitable for espresso (gives bimodal grinding), while the second has steel millstones that are more suitable for alternatives (gives more unimodal grinding). In both cases, the millstones manufacturer is the same: Ditting. So, if you look at the Baratza / Mahlkoenig coffee grinders, then steel millstones will be better for the airpress, and not ceramic ones.
Although you can drink in the aeropress within a few hours after obrazhki .. Well, that's what smart coffee gurus write. Provala, yes indeed it is possible, tasty, but it is better to drink all the same aged coffee.
Thank you so much, I will try.
I also read that aeropress and other alternative methods
can brew immediately after roasting, and in the case of espresso, you need to wait at least five days (first of all, so that carbon dioxide comes out of the beans a little), since espresso has a much higher brewing intensity than alternative methods. But, as you noticed, "it is possible" and "better" are different things.
Scott Rao even advises, if we have freshly roasted coffee, and we want to make espresso right now, grind it and wait about half an hour or an hour for carbon dioxide to disappear from the coffee: this way we will lose a little in the aroma, but we can get a win in brewing. In fact, we get such an accelerated "aging". Have you tried it like this?
I was already thinking about carob. There was a case. Only I can’t even imagine from which side to approach this choice. Previously, I somehow really ignored these coffee makers ... Can you tell me?
I myself am cool to coffee, but my wife loves it very much and I want to learn how to make good coffee.She is very fond of espresso-based dairy drinks, so I am looking in this direction a little too, but decided for now to focus only on how to make great coffee in an air press so as not to be sprayed on other areas. From what I came across, I liked:

I can't help you with anything specific, except for advice, try to find good coffee shops in my neighborhood that have:
- Coffee that has been in use for no more than a month since roasting;
- "Big" coffee grinder, espresso machine;
- A barista who knows how to use it all.
Moreover, you can try to find a coffee shop where coffee is prepared by alternative methods, using the same air press. And try drinking different coffee and see what you like / dislike. And only then decide whether you want "it" or not.
For example, I told my wife in a first approximation what and how to prepare, that the coffee should not be quite stale, freshly ground, I found some caffeine and we go and try. She can evaluate a little: here they are doing the right thing, but here they cheated in this, they didn't wipe it out, and so on: that is, she can judge a little about the qualifications of the barista by indirect signs. Recently, my wife told me that she decided not to drink coffee from an automatic coffee machine at work anymore, because there, "not very".
