I’ve been roasting on the bullet for a year and a half.
By now, I can say that achieving a light roast is very very challenging on the bullet, at least for me.
I either get grassy undeveloped flavors, baked, or over-developed roasts.
I could never reach the juicy sweet roasts that I aimed for.
Searching this topic yielded results of users frustrated by the limited convective heating of the bullet.
Now, I tend to believe that while the bullet is behaving differently than other roasters like Loring and Giesen there must be some kind of technique to achieving this goal.
Just to summarize what I understood while searching:
- The beans need to absorb a lot of convective energy in order to crack wide open on FC.
- The beans should lose most of the moisture prior to first crack. to avoid grassy flavors.
- In order to achieve the above.- a lot of hot air is needed.
- In order to heat air, the bullet needs to heat the drum which ups the conductive heating.
- because of the above, the beans tend to get darker on the outside than on roasters like Loring etc.
- F4 (or F5??) and above draw heat out the drum more than adding heat.
- The bullet is not a closed, sealed system, making it more difficult to heat air.
So - after all that being said - how on earth do I get this done right (and light ) ?
Thanks in advance all,
