ive had a botticelli for a couple of years now and love what it can do, but Ive given up doing any plug for it with the silvia or sunbeam crowd around. its a lovely machine, but like the silvia benefits from ordinary 14g baskets and an 8 or 9g single.
These are available from any coffee place but Id recommend www.coffeeparts.com
You can use the ones it is shipped with but the coffee lacks body- they are more like 12g ones.
The machine benefits from a good warm up ( at least half an hour) and then a quick flush after the heating light has gone out- just let water out without the pf in place- till the sizzling goes. It likes a fair bit of coffee- I use the fill, knock on bench, level, sit tamper lightly in, refill, level and tamp method. Also Greg pullmans tampers are wonderful.
For really good microfoam the machine loves the coffeeparts conical 2 hole tip.
