Hi there,
I guess I should pre-face this by saying that I did Barista Academy's basic training course which was great but has left me confused due to the differences in equipment.
I've owned my Silvia for about 6 months now and I'm still not happy with the resulting shots. I've almost always used freshly roasted beans (aiming to use them 7 days after they were roasted) and grind them using my Rocky. The shots always come out way too fast, almost always gushing. The shots are normally quite thick and syrupy to begin with but wane off after 5 or so seconds. The flavour is quite acrid and tastes over-extracted.
I'm using the generic double shot basket provided with the machine and measure 18 grams each time. I've experimented with different amounts from 14-20g with little differences.
I nearly always grind the beans to the finest setting because the shots are coming out so fast but it seems like it's still not fine enough. The grinder burrs are as together as possible.
During the course I used a Synesso Sabre which would allow us to pour a 30ml shot in 30 seconds, not sure if this is relevant since it's such a different caliber of machine.
If anyone could offer any advice it would be greatly appreciated as I'm having a hard time convincing the others in the house it's a good purchase at this point!
