New Machine

mimmo124

HI everyone, at my work we have just a brand new coffee machine, its a La San Marco and looks the mutts nuts

I have a querie though, Should I be expecting the coffee coming out of the machine to be as good as the old machine?

All my milky coffees apear to be the same, but the black coffees are not turning out correctly, which leads me to believe that the milky coffees are not turning out correctly either.

The crema does not seem to last anywhere near as long as before, and it does not have a consistant colour or texture.

What I am basically asking is, does this new machine need its groups to have the coffee cooked into them. Does the shiny metal inside of the group have any affect on the quality of the coffee, because the old groups were a bronze colour inside(not due to a lack of cleaning).

Any contributions would be most appreciated.

Regards
Mimmo

Mimmo, All machines take time to 'season' and the coffee should not get cooked on. The flavour will enhance after about 50 - 100kg.

Cool thanks for your reply. I have experimented for a while and have noticed that when you run the water through the head for about 15-20 seconds, the quality of the coffee coming out is superb. The only problem with this is that it takes time, and when you are busy during service it can really slow you down if you need to run the water for 15 or so seconds for every few coffees you make. In regards to your statement that i have an immaculately clean machine try and keep it that way, i always clean the machine fully at the end of each shift. Was just wondering, what colour should the inside of the group be. I thought that a bronze colour was normal, and i know that black is definately bad. The coffee that i am using is Braziliano Bar Classico, it is close if not fully 100% Arabica I thought, and would explain the crema being thin. Thanks for your help regards Mimmo

Ihave been using the same machine for 3 years and to tell you,they are very good machines appart for the problem that they run too hot,i allways had that problem and the best way to deal with it is to run the water for at least 5-10 sec,or until you dont see any more stean comming out of the water and it just pours out with out that shhhh sound,hope iam making sence..... and for your steam preassure i would not go past the number 1 on the gauge as this is very sufficient for this machines,as for your group it should be a nice golden color in about 1 week ,but allways clean them out at the end of the shift your machine should be making some very fine coffee  very soon.good luck
