Hi all
Any good tips for making a double ristretto? I want to make it as a base for a piccolo.
I have a Dual Boiler and Sette 270. How much coffee grind and how long should I extract for? I was going to aim for 18g of grind, and 24ml in 24 or so seconds, with a 5 second pre-infuse. I think it's an 18g basket, so might drop it a touch to 16g or so as well and try that with a finer grind.

I'm guessing if it's too fine, the water can rush around the sides? I have a bottomless portafilter and did notice the water coming in from the edges first before joining in the middle.
