All Your Coffee Roasting Questions Answered by Kaffelogic

Add a scoop of green beans and press start. The Nano 7 will take it from there. Want to roast darker? Press + before start. Want to roast lighter? Press - before start.

The Nano 7 plays back a roast programme that has been designed by an expert, making artisan-quality roasting accessible to everyone. When you buy a Nano 7 you get access to the full suite of design tools, but for daily use it's as easy as pressing a button.

Green beans are readily available online or from many roasteries. We did start making a list of Internet suppliers, but it is growing so fast the best option is just to search for 'buy green coffee beans' and take your pick. Better still, keep it local: pop in to your local roaster and ask. You can also get tips for where to get particularly good beans from our community forum. A number of our distributors around the world also sell green coffee, so be sure to look out for it.

Green coffee can usually be stored for up to 12 months, sometimes longer, especially if it is from the latest harvest. Store your green coffee in a dry, well ventilated environment. The ideal freshness window is usually 6-12 months.

A roast profile is a set of instructions that tells the roaster exactly how the coffee should be roasted. It includes a time-temperature curve, a time-fan speed curve, and a collection of other settings that ensure optimal conditions for the coffee and roast repeatability. There is a default profile built into the unit, and additional profiles can be stored as files on a USB memory stick for loading into the roaster.

There is no need to wait for your Nano 7 to reheat between batches. Just wait for your current roast to finish its cooldown then load it up and roast again straight away! The Nano 7 is designed to roast back-to-back with no down time.

The Kaffelogic roaster produces about the same amount of smoke as frying food. The smoke is barely visible and a domestic range hood extractor fan is plenty sufficient for removing it from the kitchen. A good extractor fan will eliminate all smell; a less effective fan will leave you with a pleasant whiff of roasting coffee. If you do not have an extractor fan we recommend running a domestic air purifier in the same room. Otherwise you will notice quite a strong smell of roasting coffee. Some people like it, others are not so keen on it. Without some form of ventilation or air filter we recommend roasting only one batch at a time.
