  • How much espresso does the 9Barista make?
    • The machine produces a shot which weighs between 35 and 40g.
  • How can I warm my coffee cup while I’m waiting for coffee to brew?
    • A good trick is to hold your empty coffee cup upside down over the steam coming from the chimney while your 9Barista is brewing. This method can quickly pre-heat your cup to a high temperature. Be careful when you do this not to put your fingers directly in the steam, as it will be hot.
  • Can I heat water in a kettle and pour that into the bottom chamber to get the shot quicker?
    • That does work, yes. But it’s not what we recommend, as there’s the possibility of burning yourself if the hot water splashes out when you place the heat exchanger into the boiler.
  • How do I know when my extraction is finished?
    • There are two ways to be able to tell when your machine has finished extracting; the first is that the espresso will stop rising in the portafilter. You should also be able to see and hear a final, stronger flow of steam coming from the chimney, for one to two seconds, which signals that there’s no more water in the boiler and the extraction has finished. You should turn off the heat at this point and pour your espresso straight away.
    • leave the heat on until the coffee stops rising, which will coincide with a second burst of steam from the chimney. As soon as this second burst begins, remove the machine from the heat.
  • Is it possible to make a ristretto?
    • Yes, you can do this, but it’s a little bit of a hack! Fill the boiler with 60ml of water, then screw the machine together as usual. Next, pour 40ml of water into the chimney. This will produce a shot of ristretto with a volume of approximately 25ml.
  • The aim is a 25-30 second extraction time. If it’s too fast, grind more finely and if it’s too slow, grind more coarsely. I hope that helps!

研磨參數

Thermomix

  • 打熱奶泡（一杯double shot約200ml奶）
    • 約1分半速度1打至70度
    • 30秒speed 8
  • 用蝴蝶棒打熱奶泡
    • 400g 5分鐘 60度 速度4
    • 200g 2分鐘 60度 速度4
  • 磨咖啡豆
    • 100g 4--6--9.5 20秒
    • Place 200g of coffee beans into mixing bowl.
    • Insert mixing cup into lid
    • Grind 20 seconds speed 10
    • Scrape down sides. The coffee grounds may smell 'hot' so allow to cool (approx 30 seconds). This will give you a better ground consistency and avoids burning the beans. Although heat is not used, the beans will get hot with the grinding action anyway.
    • Grind 20 seconds speed 10. Repeat as necessary, scraping down sides and allowing to cool between each grinding.
