IKAWA make Sample Roasters can be used worldwide.

We manufacture in both power varieties of either 220 – 240V or 110 – 120V depending on where you’re based, but they are calibrated to be equal and you will get consistent results.

To place an order, or if there are any specific questions you have, please contact to express your interest and we’ll be happy to help.

The Sample Roaster includes 12 months part and labour warranty.

This is normally carried out directly from IKAWA’s factory and workshop in London, England. In addition, our support team can assist over the phone or email.

Typically we manufacture in small batches so would normally have stock immediately available or within a short lead time.

Our Sample Roaster is designed primarily for consistent, standardised sample roasting, and also experimenting with profile roasting.

That said, it has been used by professionals to enter (and win) national and global coffee competitions.

The capacity of the roaster is 60 grams, although many of our roast profiles on the library are designed for 50g.

By using 50 grams you’re able to get two roasts from a 100g sample which is handy to allow the fairest evaluation of coffee samples.

The roaster emits very little smoke when roasting and does not require installation of extraction facilities.

It produces very little smoke due to the small batch size – and the fact that when sample roasting to light or medium roast degrees you will not burn the coffee beans, so very low amounts of smoke are emitted, however if youre roasting repetitively, or have a very sensitive fire alarm, we recommend opening a window or two.

All the chaff is contained in the collection jar and won’t make a mess of your office, lab or roaster!

The roaster lid is magnetic and can be taken off to be cleaned so you can continually see the roast happening, providing a visual experience of your sample roasting at all times.

Chaff is collected automatically during the roast, so there is no blockage of chaff to clean as you see in other roasters.

We do not recommend cleaning the inside of the roasting chamber, to avoid disturbing the PT1000 Temperature Sensor which is extremely sensitive.

This is the holy grail of sample roasting, and it’s worth noting that no sample roasters directly translate across to larger capacity production roasts.

That said, there are various theories about how you can use the insights from your IKAWA to successfully translate across to production. Theories can be around Energy Transfer Levels (see Wolfram’s blog) or matching key moments and timings in your IKAWA roasts to your production roast, something advocated by Rob Hoos (more here).

The app allows you to capture data such as Development Time Ratio, time and temp of first crack and end temperature etc, which can help you to translate your experiences across.

If you are an IKAWA customer, we’d love to get your thoughts on this as it’s a constant topic of conversation.

The roast profiles created with the IKAWA Pro App are used to control the roaster, not just to report on actual roast details which allows hands free roasting.

The IKAWA Pro App is a stand-alone application and at present does not facilitate links with any other software at present, although we have heard demand for a Cropster integration, and are planning to develop an integration.

You can download the IKAWA Pro App here to get a feel for it.

One of the exciting benefits of the IKAWA Sample Roaster is that it enables you to share roast profiles with colleagues and partners. You can do this simply via email, sms or whatsapp etc.


This is a unique feature and creates a ‘common language’ that can be used to eliminate variables when speaking with colleagues and other partners in the supply and demand chains.


As an IKAWA customer you get access to our Roast Library which has profiles developed by our team and some of our customers, which is a great way to begin your IKAWA roasting journey.

NOTE: IKAWA Pro roast profiles will not work on the Home Coffee Roaster as temperature is measured differently.

You have complete control over how long the sample roast will be, up to 20 minutes.

We have seen a wide variety of Roast Profiles and it really is great to see different users demonstrate and test their roasting theories and preferences given this degree of precision and control the IKAWA offers.

Roasts tend to be shorter than in the traditional roasters, this can be explained by the smaller quantity and great speed at which the temperature change (ie the roaster can pre-heat to 200 degrees C in a matter of seconds) – although others prefer to create longer roasts to have a longer drying stage, and match their production roast timings.

Every roast goes through the cycle including

  • pre-heating to your desired drop-in temperature
  • the roast itself
  • an automatic (and fast) cool-down of the beans in the roast chamber. You can customise the duration of this.

Proper bean development depends highly on the roast profile you create taking into account time, rate of rise, and end temperature, to name just three variables you can control.

You certainly can. We recommend using two devices to control two roasters (or three, or four) because you will then be receiving data from each roaster. The Pro App has a function to disconnect from a roaster and will then ask you which roaster you wish to connect to if more than one is available, which makes switching between two easy and avoids any interference.

The beauty of the IKAWA Sample Roaster is that you can roast coffee however you like, you just need to invest a little time playing with the different roast profiles.

It is possible to replicate /match the flavours from a traditional sample roast – although you may choose to revise your approach to sample roasting and start afresh. Many of our customers opted for an IKAWA after blind cupping IKAWA roasted coffee alongside their transitionally roasted coffees and while they didn’t taste ‘the same’, they often tasted brighter and cleaner.

People often comment that the IKAWA roasts are very ‘clean’ and this is probably a result of the high air flow in relation to amount of smoke produced – smoke will not taint the taste of your samples which may also affect a direct comparison.

When evaluating coffee samples, the IKAWA will eliminate the variable of roasting – it enables you to roast all your coffee in the exact same way, so you can focus on their actual properties and not worry about if you slightly overcooked one batch.

YES – the android app went live in September 2017 and is available to download from Google Play Store.


There are many differences between IKAWA At Home and the Sample Roaster for Professionals:

The For Professionals System; the Sample Roaster and Pr App allows a greater degree of precision for coffee professionals using the machine as a business tool to help with consistent, standardised sample roasting and profile roasting.

This includes 20 temperature profile points, 20 minutes of roasting time, ten fan points, the ability to pre-heat the roaster for high-temperature starts, and real-time roast adjustment – so you can amend the roast profile on the fly.

The temperature sensor of the Pro Roaster is located inside the roast chamber, offering very accurate temperature readings of the exhaust temperature – a relatable metric for coffee professionals. Locating the sensor here allows the roaster to measure temperature of the air after it’s passed the beans, so will take into account the endo and exothermic stages of the roast, and adjust heat sent to roaster based on these readings. This is fundamental to the roast.

There are also advanced features on the Pro App (such as ability to mark First Crack, automatic calculation of the Development Time Ratio, Rate of Rise graphs, Roast Log and ability to edit data in the table form rather than graph – more here) which all help coffee professionals use the roaster to meet business needs.

IKAWA At Home system is designed to making home coffee roasting more accessible to coffee lovers, and enable experienced home roasters the opportunity to get more adventurous with their home roasting.

The Home App is designed to help achieve this, and comes with 6 recommended roast recipes for the range of green coffees we supply.

It offers six temperature profile points, two fan points, and twelve minutes’ profile time. There is no pre-heating functioning which although is different to the Sample Roaster, it still enables excellent roasts, but the insights do not translate to production roasting.

The temperature sensor is located below the roasting chamber where it is more protected. It measures the Input Temperature of the air going into the roast chamber, so will not pick up the variations that different bean moisture levels, density etc can bring to the roast – although the recommended roast recipes are designed for the beans we supply and taste fantastic. Because roasts are based on input temperature, the curve needs to be designed differently, and the axis on the app are different too, going to a maximum input temp of 295 degrees C, compared to 245 degrees C on the Sample Roaster.

The IKAWA Home App still has the ability to customise roast recipes and share via email, twitter and text message etc, however does not have the same advanced features as the Pro App.
