Hi all,
I've been enjoying this discussion of the Lusso. I have a different question for you. With pump machines, much fuss and energy is expended with the temp adjustment to get the best out of various coffees. From what I can tell, although the Lusso has a pstat, no one seems to fool with it much. Also, unlike and HX, the grouphead seems to give a very constant temperature when pulling shots. Soooo.... does anyone readjust their pstat for different coffee blends, or more important, feel the need to? If not, why not? Is everyone getting delicious enough shots all the time that they don't feel the need? Thanks. Michael

I have adjusted my pstat on the Lusso to cut off at 1 bar. I think it makes great tasty espresso, and see no need to adjust for different coffees. Before I had an Isomac Zaffiro pump machine, and while it made great espresso, I was forever fussing, adjusting this temperature and that tamper and forever working on technique. With the Lusso my fussing is over, and I am enjoying espresso more than ever.

Adjusting the p-stat is not something to be done on an ad hoc basis with the Lusso. The cover has to be removed, and this involves unscrewing screws in the underside of the base of the machine. You could drill a hole through the side panel, I suppose, to reach the slotted screw of the p-stat, but I suspect p-stats are not designed for frequent adjustment.

Pressurized boiler lever machines are not designed to give the barista precise control over temperature, so the sort of temperature experimentation one can do with an inexpensive unpressurized espresso-only gravity-fed lever or with a relatively expensive HX or double boiler is pretty much out of the question with the Pavoni or Cremina or Ponte Vecchio or Elektra lever. And yes, the espresso is delicious all the time with the Lusso if the dose and grind are dialed in, which is not difficult.

You can make a good espresso on the Lusso with the p-stat setting anywhere from 0.8 to 1.5 bar. A setting somewhere in the upper half of that range might be optimal if you are going to pull mainly small singles. Nearing the low end of that pressure range, a manually assisted preinfusion may be advisable especially if one tends to updose with the double basket.

The wire on mousetail's spring is ~37% thicker and it has a slightly smaller outer diameter than the spring on sneakymagic's SAMA.

While on hiatus from the board over the past several months, I've been saving for a Lusso. Your review convinces me that I made the right choice and that the Lusso is the best value in a new lever machine. The bad news is that what I've saved so far is being re-routed to the Feds in a couple of weeks.

Thanks again for the great review!

I would have responded sooner to your post, Pixelator, but for some reason the first two weeks in April are always a time of terrible procrastination for me.

The Lusso is indeed well worth consideration by anyone shopping for an espresso machine. Without hesitation I would recommend the Lusso -- especially to those folks who are lusting after Silvia. Unlike Silvia owners, very few Lusso owners will come down with a case of upgrade fever. At $700-$800, the Lusso is not entry-level kit. But those with budget constraints might consider a quality hand grinder for $100+ ... and upgrade to a $300-$400 electric grinder down the road.

I have been experimenting with dose and grind on both the single and double baskets. With a lower or higher dose, 5g-7g in the single basket, 10g-14g in the double basket, and an appropriate grind, the Lusso can produce a wide range of espresso, a tight ristretto's spicy intensity, a lungo's clarity and floral delicacy, a normale's smooth cocoa and sweet caramel. But if one decides to take a break from experimentation and settle down for a few weeks or a few months with a particular roast with a dose and grind that one finds especially pleasing, the Lusso's spring-driven piston will produce consistent, repeatable results.

Timo,

Have you posted the procedures of your experimentation and the corresponding results anywhere? I'd like to read them if you have.

Cheers!

Timo,
Another question on the Lusso. What are the dimensions/length of the PF? Is it bigger than the La Pavoni. I recently fooled around a bit with a friend's La Pavoni Europic and was a bit put off by the extremely short and dinky PF handle. I managed to keep coming in contact with the metal portions and burning myself. Thanks. Michael

I have been experimenting informally, Pixelator, not taking any measurements, just to get a sense of what is possible with one or two pulls on both baskets, dosing from 5g to 7g on the single and from 10g to 14g on the double. The optimal dose depends on the roast and one's tongue, so I have no rule that could be applied equally to every roast. Though with a machine that has a small per-pull water draw, I do not strive to reach arbitrary volumes in the cup. Pull to taste. Feel free to have another if that one was on the small side

Regards
Timo

P.S. I just pulled into an espresso cup a very tasty two-pull espresso dosed to 9g in the double basket. After a light tamp, the basket looked half empty. Afterwards, I noted the line of the crema and filled the espresso cup with water to that line and then poured the water into a small graduated beaker. It had been 50ml including crema.
