Among the many details that I noticed during my investigation of the Maximatic is the provided user manual. On the one hand it does exactly what one expects: tells the user how to operate and maintain the machine and does so as well as any such manual I have read (and far better than most, including my Elektra manual). As previously indicated I have been using the Maximatic "according to the book". I should spell out some of these choices for interested readers.
- Dosage. Olympia describes the correct dose for a single shot as 7.5 - 9 g. Since acquiring my first lever machine I have used the single basket for single shots and continued that practice with the Maximatic and have used the recommended amount of coffee. My only use of the double basket is to make Caffè Americanos. As with the levers I use 13-14 g.
- Caffè Americano. The manual includes a glossary of names and descriptions of espresso-based drinks. Included in the list is Caffè Crème. When I had my semi-automatic ECM Giotto I developed a taste for Caffè Cremas (see How to make cafe cremas) and was looking forward to trying them again with the Maximatic. I switched to Caffè Americanos when I got my Elektra Microcasa a leva because they tasted better. I had assumed that the different machine types made the difference. Now having tried Caffè Crème again, I find it is my taste preference that changed. Adding hot water as opposed to adding more "diluted" espresso gives greater clarity of flavor in the Americano.
- Vacuum breaker. The test machine I have has the vacuum breaker installed in the boiler cap. The manual says to open the steam knob during heat up to release air from the boiler. Although this appears to be unnecessary (and may be from an old printing of the manual), I continue to do this with each start up. My Elektra requires this bleeding of false pressure and it has been a part of my routine for more than four years. I do it automatically without noticing as one does many things while driving a car. When I got my first Cremina, it had a vacuum breaker, but I continued to release air during its start-up. When I moved to the Millenium/2002 Cremina it also has the vacuum breaker and I continue to release air on startup. The valve on my Cremina 67 had to be de-scaled when it stopped working. I monitor the valve on the Cremina Millenium/2002 for scale build up.
- Cooling Flushes. [Edited 12/19/2009]This is a complex topic. The manual does not refer to cooling flushes. It does recommend pre-heating the brew group. After the machine has reached operating temperature the manual recommends running 140ml (a full cappuccino cup) of water through the group. I have followed this procedure and have done no additional cooling flushes. I have tasted no adverse effect from using the machine without cooling flushes. I have tasted some small temperature differences in the cup but have experienced no burnt flavors. On my Elektra and my Cremina 67, I have tasted the results of an overheated group as a burnt flavor. I have not tasted this on the Maximatic. I have made no more than three shots in a session and my practice is to make these three in succession without pause. The temperature of shots 2 and 3 is very similar. On an Elektra, after the third shot one needs to cool the group. On my Millenium/2002 Cremina I notice no heating with more shots in a session. I have not left the Maximatic on for long periods and cannot verify from experience the cooling flush that seems likely would be needed after sitting idle.
Beyond this point, I want to test the Maximatic and the Cremina head-to-head on the same coffees. I will post follow-ups on these comparisons.
