Making a Perfect Espresso on Rancilio Silvia (4K)

I use the Rancilio Silvia v3, Rocket Fausto Grinder, Acacia Lunar Scales, Atago Coffee Refractometer. 18 gram VST filter basket is also being used. Coffee is the seasonal blend from Market Lane Coffee in Melbourne.

The VST baskets are really sensitive to their dosage amount. It's recommended you stick to the basket weight or only half a gram either side. I try to stay as close as possible but I've found 18-18.3 is acceptable. The tamp is also important to get consistent, perhaps even more than the dose as that'll effect the extraction ratio quite a bit.

Refractometer isn't the be all and end all, it should be only used as a guide to check where you're landing on the over/under extraction ratio. It's surprising how used to coffee one way or the other you can become without realising. The ideal extraction ratio for espresso is 18-22%. However, some coffees are better either side of this and it all comes down to personal preference.

For those wondering, Google Home Assistant is used with a Belkin WeMo in order to turn on the machine via voice (can also do it from an iPhone).
