Top 5 Questions Asked
You will find these and many other answers on the the FAQ tab on the Koffee Kosmo web site http://koffeekosmo.com.au/
Q. How long does it take to assemble the Koffee Kosmo kit roaster
A. Not long at all. Its so easy, you can be roasting in less than 45 min
Q. Explain how the roaster agitates the beans?
A. I have spent countless hours fine tuning the agitator to have a complete mixing action rather than to push a mass of coffee beans around the roasting bowl
The main purpose of the agitator shape is to mix the beans in a specific way that is to move the beans from the centre out and back to the centre again
The action also cycles the beans from top to bottom in a helix pattern while also allowing the beans some intermittent rest time.
Q. What is the capacity of the Koffee Kosmo Roaster?
A. 300 grams to 700 grams of green beans . However the sweet spot is 500 grams to 650 grams.
Advanced users can roast up to 800 grams of green beans, dependant on the wattage of the Turbo Oven and the users familiarity of the roaster.
Smaller roasts under 300 grams are also possible with a little tweak to the agitator
Q. Does the chaff separate from the roasted beans?
A. Yes approximately 98% of the chaff is redirected by fan force to the outer liner
The chaff collected in the outer chamber separate from the roasting beans until you dispose of them
Q. Can I expect to get professional roaster quality roast?
A. Yes its been proven by many users and testers that the home roast results are equal to store purchased beans

Coffee Roasting Facts
Fact 1: Coffee “shrinks”; it loses weight up to 20% during roasting, while swelling up to three times the original green bean size.
Fact 2: The longer you roast coffee beans, the darker the colour and the higher the “shrinkage”, e.g.…, the more green coffee it takes to make a roasted kilo.
Fact 3: Normal shrinkage is 20%; on darker roasts shrinkage goes as high as 25%. Lightly roasted coffees can have shrinkage factors as low as 11%.
Fact 4: Coffee that is light roasted as a general rule is best for pour-over brew methods e.g. French Press, Siphon, Vacuum brewers.
Fact 5: Under-roasted coffee has a flat, green, grassy astringent flavour. Over-roasted tastes burned or “caramelised” and the variable flavours of the coffee are lost in the dominant taste of the roast.
The easiest thing to do is throw the book out and - “Please, please... just roast.”
Roast too dark, roast too light, try them both then roast just right!
Cataloguing and making your own library of roast profiles of what works for you on your Koffee Kosmo Roaster for your own taste is by far the best bet.
