Nice video, can you explain what it means to increase or decrease the RPMs of the coffee?

[@giesencoffeeroasters]

Hi, glad you like the video. Increasing or decreasing the Rotations per minute (RPM) influences the way the beans move inside of the drum (Rotational force, also called moment). With a higher RPM the beans can stick to side op the drum, while a low RPM can cause the beans to lay still at the bottom of drum, both can cause scorching. The overall goal is to set the RPM at a rate where the beans constantly move inside the drum.

5% post first crack dev on anaerobic coffees? thats wild.. i might have to try the 9% for a few of our coffees, until recently i have only felt good at 12% .. may i ask for those 9% coffees are you really stretching out maillard into 4 minute territory and then dropping less than a minute in FC? (I of course i understand we are generalizing here)

[@giesencoffeeroasters]

We asked Manuel for clarification and this was his reply: Hey! I stretch out as much as I can, the Maillard also start with high flame and lower the flame through out certain temp markers. Also i noticed, i measure the crack different to another roaster in Panama. I usually wait 3 consecutive cracks to count it as FC. 6% is for extremely funky anearobics. My usual profile is 9% and if it's for espresso 12%. Manuel also adds that he uses a charge temp of 84C for anearobic. Hope this gives more insight in the roasting process of Manuel, you can reach him at Coffeetopologist on Instagram.

thanks i really appreicate the reply. very helpful @@giesencoffeeroasters

[@ChastitysNook]

​@@giesencoffeeroasters apologies for asking but could you confirm that the charge temperature mentioned is 84°C and not 184°C? 84°C sounds quite low.

[@SlayPlenty]

so why does scott rao swear by 25% dtr?

[@pscoffeeroasters]

Partly because Scot doesnt measure the FC when its heard. Its slightly earlier.
