The only real things the machine can influence are driven by pressure and brew temp. For tempurature, too hot=bitter, too cool=sour.
If you are pulling 10 second shots the grind needs to be tightened up a lot. Quote:

If you have an instant read thermometer, test what your water is coming out at, and how long after you've started the machine. I found on my older machine, 45min to 1 hr really gave the system a proper warm up, and ensure that your portafilter is in there to get warm as well, otherwise it's a huge heat sink.
As others have said, if you're extracting that fast, you need to get grind much finer. general guideline I used from my newer machine was first drops between 5-7 seconds, and finishing a double shot between 25-30sec. then fine tune from there. |

Also research Silvia “temp surfing”. This is undoubtedly the reason you are getting bitter shots with only a 10 second extraction.

can anyone recommend a stick on temperature sticker for the grouphead?

For consistent temperature that should be close to ideal, I have found the following works well in general or as a good start to dial further:
- Heat machine for approx 45min. and temp light should be off - Run w/o coffee thru the portafiler to heat cup and get temp light turn on - Watch for temp light to turn off again and pull shot starting 45 sec after Never felt the need for a PID with the above technique. The obvious has been recognized with respect to grind. I would only add that while the Rocky grinder is very nice, if you are looking used, something stepless is even better to dial in a Sylvia. Bonus if you can find and justify a good deal on a Mazzer Mini, which has gone up a chunk in the 14 years since I bought mine. |

So, looks like the free grinder can’t grind finely enough. Fortunately for me, I live a block away from a great coffee shop, so I went back and bought more beans but had them grind them there. This was my control, though I know the flavour will die after a few days.
I made on this morning that actually tasted like espresso - extracted for 25sec and had crema. It wasn’t very good I would say, but it wasn’t bad - a start. I have it to my daughter with steamed milk and she thought it was gross 🤮 |

Ha! In a week's time, she'll be pulling shots like a pro, and you'll be wondering how she does it.

I recently expanded my making coffee kit list - partially because I bought a camper late last year.
9Barista espresso machine: And a Kinu M47 grinder: So far I've been using the espresso machine on the stove, where it makes great tasting coffee. I'm looking forward to using it in the camper now I've got my settings dialled in. |

Very cool Neil! I looked at the 47 last year as a hand grinder for travel, but ended up with a 1ZPresso, which works well mocha pot and espresso when I’m on a road trip.

In other news, my dad visited me last week and said he reckons my 1ZPresso JX-Pro was a superior grinder to his Baratza Sette 270w so even though I've been enjoying this grinder for well over a year and recommend it to everyone, my purchase finally feels validated. |

I have a Gaggia (Pavoni) lever machine, which makes what I think is very nice espresso. I actually prefer the espresso from the 9Barista - its more complex, with more flavour notes apparent, from exactly the same coffee that I use in the 105. But, it's much more of a performance to use, so whilst at home I use the lever.
I bought the camper to be able to race my mountain bike this year (I'll be the 45 year old on a bike thats performance outstrips his ability by around 1,000%), and the idea of being able to make myself an excellent espresso, in a field, having just got up ahead of a days racing, is one that I am looking forward to realising. Living in the UK there might be some (or, frankly, lots) of rain to interfere with this vision - but we'll see. I will admit I love how clever the design of the 9Barista is. |

This is EXACTLY why I want one. Looks like a pain to dial in, but I will forgive some function for it's form.

manual grinders. So, I would have no problem with using one of these if they are durable and produce a good grind. In fact, I hate the sound of the motorized ones and would be happy to do without the noise! It is low production at our house - *(one per day, maybe?) so its not like I am working in a coffee shop.
Can anyone tell me if these hand grinders are good enough for the Silvia? |
