My time with the Lusso ends today, so I decided to do some side by side comparisons with the Lusso and Elektra Microcasa a Leva.
The two machines are similar but different, does that make any sense? It is like comparing two E61 group machines, i.e., while they may appear on the outside to be the same, they are two different machines. The Elektra uses a spring lever group bolted directly to the boiler while the Lusso uses a spring lever group that is frame mounted and actively heated via a thermosiphon line. The Elektra uses 49mm group while the Lusso uses a 45mm group. The spring assist on the Lusso is noticeably lighter than the Elektra but the piston travel feels around the same. One little difference between the two machines that jumped out at me today: the Lusso's short and wide stance combined with its little rubber feet make it very countertop steady. While I was trying to work a stopwatch, camera and cup placement with one hand, I had to hold the lever down with the other hand. While both machines have wide bases and are not prone to tipping over, the Elektra would wiggle around while the Lusso never moved an inch.
Today I was using Greenline, which is Metropolis Coffees' signature Redline blend in the green for home roasters. The coffee was roasted 5 days ago and kept in an air tight container until today. The grinder of the day is the Cimbali Max. I was not trying to duplicate shots between machines but produce 3 consistent shots from each machine. My definition of consistent:
- Dose within 0.1 gram,
- No difference in shot volume measured with a graduated shot glass,
- Extraction time +-2 seconds but preferably +-1 second.
With the Lusso I have settled on an 11 gram dose in the stock 45mm double basket using a light tamp and suitable grind. I use a 5 second preinfuse lever hold, release the lever and allow it to make a full stroke, re-cock the lever, hold for two seconds and release. After a couple of grind adjustments, the next three shots were well within acceptable timing. The little Lusso dispensed just less than one ounce with crema but the scale showed it produced just over 0.8 ounces by weight. All three shots were close in flavor and typical of what I have come to expect from the Lusso.
The shots from the little machine that could are an interesting mid ground between the thick and heavy bodied shots of the manual levers like the LaPavoni and the light bodied but bright and acidic Elektra. The Redline pulled lighter in crema color, but still produced a fair amount of crema with nice tiger striping. The flavor was light with hints of floral with some pit fruit in the background with no chocolate notes. I was getting a fair amount of earthy peat, presumably from the Sumatran in the blend. The shots had a nice palate coating creamy consistency, but it was missing the heavier butter mouth feel that the manual lever and some pump machines produce. This blend was actually kind of flat and not one of my favorites for use in the Lusso. It was good, but unremarkable.
The Elektra Microcasa Leva has been my benchmark for bright and clear espresso. I find that it produces one of the more unique cups of any machine I have used. For the Elektra Microcasa Leva I settled on a 13 gram dose in the stock double basket. With the Microcasa I use a pull and a half on the lever versus the two full pulls on the Lusso. I lower the lever, hold for 5 seconds and release. Half way through the first lever stroke the espresso is just starting to flow from the portafilter. I then lower the lever, hold for two seconds and let the shot flow to completion. In my metered shot glass that put the volume at the very top of the glass rim. When weighed on the scale it was one ounce, the timing was slightly slower on the Elektra and the shot more ristretto than what I produce from the Lusso.
Again my coffee was home roasted Redline. In the Elektra I had more floral and fruit notes with the peat note I got in the Lusso having transformed into just a hint of chocolate. The mouth feel was slightly heavier than the Lusso, but not quite as creamy. There was much more life in the cup than Lusso produced with the same blend. This coffee worked best in the Elektra.
I have noticed that some coffees work better in the Lusso than the Elektra and vice versa. As a general observation, the Lusso appears to favor slightly darker roasts that are heavy in the chocolate and spice. The Elektra tends to work better with lighter roasts that accentuate fruit and floral overtones. That may be due in part to the design of the machines. The Microcasa tends to produce high peak brew temperatures. I also like the Lusso's ability to be turned on and left on for extended periods without overheating. I have run the test unit for 48 hours with no issues and only turned it off to fill the boiler. The Lusso however cannot compete with the Elektra for build quality and counter top presence. The fit and finish of the Elektra Microcasa unmistakably better.
I have enjoyed using both machines. They have proven to be complementary to each other in flavor. I have enjoyed the Lusso; if you are looking for a spring assisted lever machine that's a price performer, the Lusso will fit the bill nicely. Don't expect the fit and finish of a premium sports car; it is more utilitarian but will get the job done.
