Could you roast coffee in an industrial glass kiln and it be drinkable?
A strange question and purely hypothetical. This came about with a discussion with one of my friends who is a glass maker at university.
My first thoughts was that you could not control the temperature enough, however he did state that with glass making, the art is in how fast you can heat and cool down the kiln. So in effect, I don't think the temperature control would be an issue. I feel my issues are:
- Rotating of the coffee during the roasting (as it would not be in a drum). It's possible to "spin" glass in this way.
- Post roast cooling, would there be a way you could make a makeshift cooling bed that would be somewhat effective.
Drinkable - I guess this depends on personal taste, so for the sake of this exercise I will state that drinkable as the quality of instant coffee. So something you would drink to be polite but not find any pleasure in.
