Timo, it's fine to have a theory about what baskets extract better. But it's high time you stop stating this as a fact, especially to people who may not know that it's simply your speculation.
You keep stating this as if you've personally confirmed. Instead you don't have a shred of evidence. How many 58mm machines have you used? How many singles have you pulled on them? Where's your data?
The evidence is all the other way. In Italy, 95% of the shots pulled are singles, and at least 95% of the machines have 58mm baskets. If the singles were really worse, would they have continued using them? I'm no expert in small gauge lever machines, but mostly I've had better luck with the double basket on them, since the singles tend to hold very little coffee if one allows sufficient clearance.
Your theory about the depth of the puck in 58mm single baskets shows you are not fully conversant with their design details.
<image>
The LM and Faema baskets hold 7 grams in the central portion of the basket, which is, in effect a mini-basket with the correct aspect ratios. LM figures the pure cylinder design works better, Faema thinks a slight conical shape is better (both carry these ideas to their double baskets). The Faema basket can be updosed, the LM basket cannot (profitably), and requires a 48mm tamper. The Rancilio basket, which has coffee spread over multiple steps when dosed with 7 grams, is unusable; at least, I couldn't get a non-channeling shot after a day of trying on three separate machines.
Finally, a theory stating that one can extract better with the same coffee in a long, thin cylinder as opposed to a short wide one is shaky overall. Channeling problems increase as the depth of the coffee cake increases -- this is the bane of the towers where instant coffee is made, and is turning into the bane of superautos. One needs a minimum depth to prevent the cake from dissolving and maintaining it as a control on the brewing speed. But beyond that, the lower portions of the cake extract into coffee rather than water, and at different pressures and temperatures from the top of the puck. The trend in design has consistently been towards wider gauges to create a more uniform extraction.
The tallish narrow conical single baskets on these vintage domestic machines, baskets that taper to a filter under 30mm in diameter, seem to keep fines from migrating downward into the cup and I suspect the thickness of the puck is responsible for that. Now, couple this tallish-narrowish basket shape with a spring capable of producing no more than 6 bars, and you get a gentler extraction which even further reduces the release of solids.
...
I'm not saying domestic spring-driven machines are the cat's meow, but only that the espresso they produce is different in its quality from machines that operate 1) at higher pressure, 2) at constant as distinct from waning pressure over the duration of the extraction, and 3) with wider shallower baskets.

But if a newbie asks a question, don't give your extraction theories as if they were a fact; it's uninformative at best, misleading at worst.

My only reason for posting here is to ask you to not give your purely personal opinions as if they were fact to people who don't know your posting style. It seems even this very plain request is fruitless; and I and others will continue to be forced into these tedious clarifications.

In summary, the Achille is breaking new ground in the home lever machine market. It combines many of the sought after features of a lever machine while delivering some pump like shot nuances. And let's be honest - lever espresso machines have a reputation of being difficult beasts to master. For the Achille, that simply is not the case. It is very easy to learn and quite forgiving, even for a novice lever operator.

timo888 wrote:A lever is an excellent choice for a beginner. Because of their narrower/taller basket shape (they usually run between 45mm and 51mm diameter, with Achille's standard 'commercial' 58mm basket being an exception) together with their manually controlled brew pressure, manual levers are more forgiving than a pump machine.

timo888 wrote:The review praises the Achille for its "pump like shot nuances". If pump-like shot nuances are different than lever-like shot nuances, then these nuances could be a reason for someone who is looking expressly for a lever machine to choose another model (Elektra, Ponte Vecchio, Cremina) over the Achille?
