Some coffee roasters are puzzled by a phenomenon where they can’t hear a prominent first crack during the roasting process, despite indications of medium-dark roast. This issue seems to be particularly prevalent with certain coffees like Colombian, Guatemalan Huehue, and Natural Brazilian. Let’s dive into this intriguing conundrum.
First crack, a significant event in the coffee roasting process, is characterized by an audible popping sound as moisture within the beans begins to evaporate. The first crack usually occurs around 350-400°F (176-204°C) and marks the transition from the drying phase to the development phase. However, it appears that with certain coffees, this critical event can go unnoticed.
The silence during the first crack might be due to a few factors. One possibility is roasting profile optimization. Every coffee bean type has its unique flavor profile and ideal roast level. If the roaster’s settings are not precisely tuned for these specific beans, it could lead to a faint or absent first crack. Another factor could be the beans’ moisture content at the start of roasting. Drier beans might produce a less pronounced first crack.
1. First crack is crucial in coffee roasting and marks the transition from the drying phase to the development phase. 2. Some roasters may experience a silent first crack, which could be due to suboptimal roasting profiles or improper bean moisture levels. 3. To address this issue, it’s essential to fine-tune roasting settings for each coffee type and ensure beans have an appropriate moisture level before roasting.

Questions & Answers
Why don’t some coffees produce a first crack sound?
The first crack in coffee roasting is the audible indication of the start of rapid water loss. If no first crack is heard, it could mean the beans are under-roasted or not suitable for this stage due to their variety or roast profile.
How can I ensure a first crack with my coffee?
To hear the first crack, maintain a consistent temperature and roast the coffee for approximately 5-8 minutes after you start hearing popping noises (the second crack). Adjusting heat and time according to your roaster’s settings can also help.
