eisWhat is oven roasting?
OVEN ROASTING ISculture怎么读>西瓜的英文单词, TO the coffee devotee community, one of the lesr-known (and certainly less often talked about) roasting methods. The machines that people em to know most about and u the most are hot air roasters (popcorn poppers or commercially available small quantity roasters like the Imex, I-Roast, Hearthware Precision or the Sivetz
sample roaster) or drum roasters (homebuilt gas or coal BBQ Roasters, or electrically-heated small-quantity drum roasters like the HotTop, or the Alpenröst).
When I started roasting, I had no idea all tho fancy roasting machines even existed. I simply did what my girlfriend at the time had learnt at the local coffee hou (Mauritz Kaffe, mentioned below) and had told me: u the oven. It wasn’t until after a year of reading and posting ffee and arching the coffee resources on the internet that I started to reali almost nobody outside of Göteborg us To me this is very strange, and I wonder if it could be an indirect result of the widespread myths about the mysteries of coffee roasting that have been around since the late 19th century or so. If it is so hard to roast coffee, surely you can’t u something as obvious and common as the oven? Seen from another point of view, almost any food can be prepared in the oven with great results. Why not coffee?
Oven roasting pros and cons

IT SHOULD ALSO BE said that some people just don´t like the taste of oven roasts. But of more significance is the views of coffee gurus or celebrities that dissuade people from trying the oven becau it is not “good enough”. Among others we have Kenneth Davids, who thinks that oven roasting in conventional ovens (contrary to gas ovens, which he likes) doesn’t work becau the results are too uneven, and that fan oven roasting with its longish roasting times yields a muted aroma (read his book “Home Coffee Roasting, ISBN 0-312-14111-4, most of it is on p132-133.). His book is good and I like it a lot, but this, in my experience, simply isn’t true - at least not for a reasonably large (roughly 60x60x60 cm externally) European standard 220-240V oven. The oldest coffee hou in Göteborg, Mauritz Kaffe, is living proof that conventional oven roasting works in a commercial environment with demanding customers. They also ll green beans and hand out a small leaflet with much shorter instructions than in this tutorial, telling people how to oven roast, which is probably one of the reasons for oven roasting being popular in Göteborg.
But the oven does have its own taste profile, as do all roast methods. To be fair, if we su
