Roast profile

‍
When you're roasting this Colombian Mandela from La Esperanza, you want to keep a few key things in mind. The origin, the natural processing, and the target finish temperature, which in this case is Medium Light, all play a big role in how you approach the roast. I set the gas pressure to a medium level to balance these factors.

Now, something interesting about this Mandela and Java from La Esperanza is that they behave differently compared to Potosí Colombia. Specifically, the Max Rate of Rise (RoR) tends to be lower. Also, the first crack happens about 3 degrees earlier than what you'd expect with other naturals.

Here's what you need to do when that happens: If the first crack comes earlier by more than 3 degrees, you should increase the gas pressure and lower the charge temperature. These two adjustments complement each other well.

So, remember:

1. If your Max BT RoR is low, raise your charge temperature.
2. If the crack happens at a lower temperature, you might want to lower the charge temperature and optionally increase the gas pressure.

These tweaks help you manage the roast better and keep everything on track. After this, I recommend trying a profile with a slightly higher finish temperature by lowering the gas pressure and raising the charge temperature. Then, compare how the flavors develop in the cup. This will help you decide which profile to lock in for this bean.
