A quick recall of how I ended up here today. I lived in Italy for just over five years, where I got into espresso, and due to that I was able to obtain espresso machines for prices that far undercut those in the US. This included purchasing the Bosco, which I got without paying for distributor and shipping costs, the latter occurring due to my affiliation with the US military, which pays for a move. I purchased two machines prior, a La Pavoni Professional and Elektra Micro Casa a Leva that I heavily used in sophomore and junior year in college in New England, and for my senior year I intend to bring the Bosco to my dorm, to the delight of my roommates (in terms of security for the machine I fully trust my roommates and the campus security for my dorm for anyone concerned).
The full story up to now can be found in prior threads of considering the purchase then follow up results
Considering Purchasing a 1 Group Bosco Sorrento
Construction of a Bosco Sorrento
My Bosco is a 110V one group Sorrento with orange panelling and wooden knobs/handles as add ons
Now to the fun part and namesake for the thread: the unboxing.
The crate my Bosco was held in is quite durable and well built. There are 12 screws each holding the top cover and part that connects the upper wall to the secured bottom pallet. The machine is protected first by layers of inch thick styrofoam followed by bubble wrap. Finally there is cellophane wrapped around the machine that also secures the box containing the accessories for the machine. In the machine itself all removable panels (drip tray, grill for drip tray, and cup holder) had pieces of bubble wrap placed to prevent scratches from wobbling during transport.
The accessories I received are:
- -1 single portafilter
-1 double portafilter
-1 ⅜" threaded cable for the inlet
-1 ½" wired tube for the drain
-1 instruction manual in English
-1 58mm tamper with the Bosco insignia etched on the metal tamp
-1 tamper holder in wood
-1 Lever with wood handle
I unboxed it the prior night because I wanted to check if there was a plug already inserted for the machine as all commercial machines I have purchased do NOT include a plug. Just a wire with stripped ends for placing a plug. This did occur, but fortunately today the electrician was stopping by to install some outlets for me dedicated for the machine. The machine uses a Nema 5-20p adaptor and is plugged into a GFCI Nema 5-20 outlet.
I purchased a lightly used Flojet 5000 from a fellow HB user, and I hooked it up with a T-connection with a valve for when I wanted to drop the pressure in the hose line. You will need a ¼" to ⅜" John-Guest to BSP connector at the minimum if you do not do anything beyond using what is provided with the Flojet and Bosco. Otherwise I utilized ⅜" tubing using a provided adaptor.
Once the outlet and plug were installed I plugged the Flojet first to utilize the manual water knob. It was only when I saw water on the sight glass that I plugged in the Bosco. Once it is turned on the automatic water level will activate and finish filling the boiler. From heat up it will take over an hour, maybe 90 minutes, before you can attempt pulling a shot. I gauged it by feeling the handle of the lever to see if it was warm to the touch.
I had a temporary setup to check if there were any leaks from the inlet tubes but so far besides the manual knob everything is ship shape so far.
The pressurestat was set pretty high initially, at 1.5 bar. I adjusted it down to 1.1 bar for a starting point. Just of note there is a small yellow plug where you would adjust the pressure. YOU NEED TO REMOVE IT TO ACCESS THIS SLOT. A related issue is my manual water knob will leak where the plastic knob and thread joint meet. I am trying to figure out how to fix it but no dice so far. It leaks more when the pressure is higher or when the pressure is increasing.
For my first shot, I loaded up 14g of Saka Gran Bar on the same grind setting used for my Elektra. I tamped, locked in the portafilter, and pulled. The result: SOUR NASTY SHOTS. In reality it took my until my fourth shot to produce something great, which I think is not bad considering I have never used the machine prior! The final result is 1 'step' from zero on my Lido E and 16g of coffee. I will probably be able to tweak it more but the shot quality produces something that already exceeds my home levers in flavor. The notes are more defining, dominated by vanilla and nuts followed by chocolate and a bit of caramel. These notes are what I expect from my shots and am basically in coffee nirvana right now after six shots of espresso. It will take some time. This is where I am currently at up to now. Totally worth it.
