“We use our IKAWA Pro Sample Roaster for coffee sampling. It works well with the small green sample packs we receive.
I was originally drawn to the IKAWA as it has a small footprint, it’s ease of use, and ability to see the roast curve in real time and adjust on the app – and simply the innovation behind it.
It works pretty well for our application, which for coffee sampling. We found the IKAWA surprisingly easy to use – you won’t be disappointed (except that it’s limited to iOS)!
It wouldn’t allow us to completely transfer the profile curve on the IKAWA to our Loring production roaster, but it works for what it’s intended to do, which in our case is to determine if the coffee meets our target flavours and quality – and consequently affects our green coffee buying decisions.
We tend to use the IKAWA to profile roast, almost to a standard profile that we’ve developed.
At times we’ll use the sample roaster to experiment with small adjustments on the profile. The results are pretty consistent, which is what you want when sampling; either the same coffee or comparing across different types of coffees, so that you can be sure any flavour differences are not due to factors on the equipment.”
