Why do you need a Giesen sample roaster?

Willem Boot, Giesen Ambassador and owner of Boot Coffee explains this question in his blog. 

 “Over the years I have roasted with almost any model of sample roaster on the planet. I’ve come to the conclusion that I truly love the performance and capabilities of the Giesen WPG1 sample roaster. Giesen introduced this roasting machine and its performance beats hands-down all other drum-operated sample roasters available on the market.” 

Roast, learn and repeat.
