One week has passed since I first started up my machine, and here are some thoughts after pulling about thirty shots so far:
I heavily recommend investing in an automatic timer for the machine because of the long (70-90 minutes) heat up time without flushing the group. This will allow you to wake up and immedietely pull a shot without sleepily tapping your foot as it warms up. If you are done for the day early you can just switch off the machine and turn it on again after the designated shut off time has passed.
You will use more water with a commercial machine than with a home lever from flushing and frothing. With my Elektra and Pavoni I used around seven gallons total over about 500 shots pulled during my junior year in college. Not counting the initial boiler fill up I already have used a little less than a gallon for the thirty shots in the Bosco.
Using a plastic shelf cover will protect the cup holder from scratches. To ensure the cups heat up with this addition placing towels on them will keep the heat in and heat them up faster.
If you are coming from a domestic machine the commercial steam arm on the Bosco is far more powerful than what you may be used to. I can froth a pitcher of milk in half the time I needed for the Elektra (which I considered a fairly strong domestic steamer). I see no reason right now to switch out the default 4-hole tip. You will also have a hot water arm that is useful for purging water or making americanos. I do not personally see myself using it too much unless I really wanted some instant hot water for Ramen noodles or tea
The 1 group Bosco can hold 4 espresso cups per row front to back and just barely 3 cappuccino cups. Overall a mean estimate for the tray capacity with just espresso cups is 24. You can double stack the cups if you wish but that is almost overkill for the number of shots you would pull in a session and I do not know what the weight limit is for the tray but I do not want to dramatically find out through failure.
After waiting over a year and finally using my Bosco is a little hard to describe besides maybe Euphoria. Every time I walk by I want to smile when looking at it. It is my own little commercial bar in my house. Where can I find this high quality of espresso near me? Where can I find espresso this cheap, paying 13 cents per single shot! Quite difficult to say the least. I also find myself wanting to use it as often as possible. I actually pester my parents to invite friends over just so I can make them a shot. Every single worker that has stopped by our house has received espresso from my Bosco or Elektra. It's fun to use I daresay.
The final question I would ask myself is if the Bosco was worth it. This may be a little difficult to define if you are looking for the best deal. For me I can already answer yes to that question as I already know what I will be getting out of it based off my initial requirements for a commercial machine.
I wanted a machine that was:
-Made in Italy, preferably from Naples
-Is a spring lever
-Has character (ie something beyond the billion steel boxes of e61 machines in the prosumer market)
-Is relatively unique compared to other hobbyists' machines
-Is long lasting
-Is simple to maintain
-Is 'reasonably' priced (my initial budget was $4000 but I got it for less)
The Bosco satisfied all of my requirements. If I did not know Bosco or was forced to select something else brand new I would have selected the Profitec Pro 800. Otherwise it would have been a used La San Marco 85 Leva or vintage machine as my primary selection. To conclude, I am quite one happy customer of Bosco and cannot wait for tomorrow to pull my next shot.
