What People Say

‘First, I was hesitating to buy a Giesen roaster, because I was used to two smaller roasters from different brands. I thought it might be too flexible and I didn’t want to lose myself in all the settings. But once I did my first roast on the W15A, I knew I would find my way. With this roaster it’s so easy to roast stable and you can’t really get a bad roast out of it. I love every second of roasting on my W15A. Also, I think you have the best possible support there is, not that I needed it a lot. It’s good to know that you’re not totally alone with your roaster. Giesen has got a great team behind it!’

“We saw what you do and how you do it. It felt like a proof of quality. You gave us the experience and knowledge to complete this project the way we wanted it. Giesen played a big part in how we built this roastery. Your staff knows the market and understands us and our needs.”

“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.”

'I'm a fan of your products! We own our little Giesen W1 roaster for about five years now and are expecting to get a Giesen W15A at the end of the Summer. We love the W1 because it's really intuitive, friendly-looking and a perfectly working machine. Plus, I'm really happy with the service and quick responses when we needed to solve some technical issues. The roaster was one of the key elements in our previous slow coffee bar and is now part of our local coffee school.'
