Did you know you can do a manual pre-infusion on a cheap machine? My machine doesn't have a three-way solenoid valve. So it doesn't release the puck pressure and suck excess water into a drip tray.
A lot of cheap machines don't have this function. Just prepare your puck as usual. Maybe grind a touch fine. For example, I grind at 5 on the G7, but for this shop I went at 4.5, jusy to try and keep the resistance in the puck when the machine starts again.
Run your machine until the first signs of espresso show, then switch it off. Then start your shots again. Sometimes the preinfusion is a bit lacking on this machine and this is a better option.
It is trial and error, but it can work well. If I preheat my group, I can even pull off some light roast espressos with a long preinfusion. This coffee is a classic Colombian from .
Have you ever tried this trick? If not maybe you should. There's no right or wrong. Just a good result or a bad result. Tastes good, or try again.
I have not been asked or paid to produce anything. I just love messing about and experimenting. Shout me a coffee if you're feeling generous. ā¤ļø
19/42/30 with 7s preinfusion. Makes an r3ally good milky. Nice and balanced espresso. A bit fruity and citrusy black, full on caramel nougat in a milky.
