Is my stove compatible?

The 9Barista machine works on all domestic cookers, from electric hobs, including induction, to gas or Aga or even a gas camping stove. Below is a little additional information to help get you started, whichever type of stove you’re using. 

Choosing the heat level

You can find the best heat setting by following these steps:  

  1. Use the initial recommended cooker setting (listed below for each cooker type)
  2. If the machine produces espresso in under 3 minutes, turn the heat down a little for your next cycle. If it takes longer than 6 minutes, turn the heat up next time. 

Warning: Whichever stove you use, it’s very important that you never leave your machine on the heat for over 8 minutes, even if it hasn’t produced any coffee, as this may cause the upper chamber to boil dry, or the safety ring to activate. If it didn’t work, try again with a higher heat setting.

Domestic Gas Cookers

  • Burner: use the burner which is closest to 3 inches in diameter
  • Heat exchanger plate: you will need to use the heat exchanger plate
  • Heat setting: begin by using the maximum gas flow setting. If the machine produces espresso in under 3 minutes, reduce the heat as necessary so that espresso appears between 3 to 6 minutes.

Electric Ceramic (the ones that glow red)

  • Ring: use the smallest hob
  • Heat exchanger plate: not required
  • Heat setting: begin by using the maximum power setting. If the machine produces espresso in under 3 minutes, reduce the heat as necessary so that espresso appears between 3 to 6 minutes.

Induction

  • Ring: use the smallest ring, usually around 12cm in diameter.
  • Heat exchanger plate: you will need to use the heat exchanger plate. 
  • Heat setting: start with a 75% heating setting
  • Additional information: some induction hobs can be a little tricky, as they turn the heat down when it reaches a certain point. This article provides some additional help if you’re having trouble with your induction hob. We’ll soon be launching a new induction-specific heat exchanger plate, which will remove these difficulties.

Aga

  • Ring: Use the high temperature side
  • Heat exchanger plate: not required
  • Heat setting: you don’t have

Camping gas stove

  • Heat exchanger plate: not required, but may be used, especially if it helps to stabilise the machine
  • Heat setting: start with a medium to high heat

Hot plates

  • Hot plates are a potential solution if you don’t have a suitable domestic stove. However, we’ve tested a few different types and have seen variable results. We can recommend this one, which is available in ceramic and cast iron versions; we’ve seen that the ceramic one works best with the 9Barista.

Are there any types of stove which won’t work?

Yes, there are. Unfortunately low pressure alcohol stoves are unlikely to work, and the same is true of Trangia-style camping stoves. This is because they don’t produce sufficient power to get the machine working.
