My first roast impressions

[donovasvan.yxS4]

Hi everyone, I’m glad to share with you my first roast on the Bullet.

I would really appreciate reading your opinions about it. It was a Guatemala Huehuetenango washed beans, and I have some questions to ask you:

• Why the B-RROR curve is too low? I have charge at 220º as it the first guide says.
• I see a lot of chaff, how could I eliminate it without using a very high F at the end?
• What do you think about a 10% lost weight?
• 9% development time seems too short but I was following the first guide and 60 seconds after FC seems fair to me looking at the color as well.
• It is too hard to me marking the YP, any references?
• How long should I take to try this coffee as espresso?

Thank so much for reading and answering.

• Why the B-RROR curve is too low? I have charge at 220º as it the first guide says.
  -There doesn’t seem to be anything wrong with your curve? what makes you think that the B-ROR is low? what are you comparing to?

• I see a lot of chaff, how could I eliminate it without using a very high F at the end?
  The only way I see to get rid of chaff on a clean machine is to use the fan, unless I am missing something super important

• What do you think about a 10% lost weight?
  10% seems low but as long as you like the flavour you are good to go! Take a look at Rob Hoos blog post about weight loss, maybe it’ll help (Why take weight loss % — Hoos Coffee Consulting)
  Also your profile says 12.6% loss which looks pretty good.

• 9% development time seems too short but I was following the first guide and 60 seconds after FC seems fair to me looking at the color as well.
  Taste the coffee and see what you think, if not to your liking try the same roast but go for longer dev%

• It is too hard to me marking the YP, any references?
  I consistently mark at either 140 BT or 170 IBTS depending on what my sight is telling me. My tip is to be consistent with marking and you will have less headaches roasting

• How long should I take to try this coffee as espresso?
  I usually wait 7 days or more. If I’m having troubles dialing in, I wait a bit longer.

Hope this helps! Cheers!
