12/5/2023 0 Comments Flick my bean coffee![]() We can recognize these three problems as something other than the desired gentle, steady development of your coffee. This typically happens around 2 minutes after first crack. Once the moisture escapes and vents out of the roast chamber, the beans have a tendency to quickly heat up again, and the RoR will rebound. This usually illustrates itself on a roasting curve with a sharp RoR crash.įlick. This blast of moisture, now entering the roasting chamber, briefly cools the beans. As that hot moisture/mass suddenly leaves the beans, the bean temperature falls rapidly. When the beans start to crack, they begin an exothermic release of heat, energy and moisture. ![]() Experienced roasters recognize this as the coffee approaching first crack.Ĭrash. If you’re not watching a chart, you will notice the beans start to emit an increasing amount of smoke/steam as they swell up. The bean temperature starts to creep upward, as seen on the chart. As coffee approaches first crack, the moisture in the coffee is heating up radically, but with little opportunity to escape. Conceptual understanding also helps those who don’t have access to computer readouts manage their roasts intuitively. We believe it’s super helpful to understand what’s going on with your coffee during these critical transitions so you’re motivated to manage your roasts. The crash can bake your coffee and the flick can char your coffee, upsetting the delicate flavors you were hoping to highlight. Mismanaged roasts will often show a rate of rise that bumps up slightly before first crack, plummets during first crack, and then shoots back up sharply towards the end of first crack. These terms are relatively self-explanatory when looking at the roasting curve above, but refer to the seemingly natural behavior of your RoR before, during and after first crack. ![]() ![]() We alluded to a few key inflection points that we’re going to dissect further this week: the Rise, Crash, and Flick. Last week we talked about roasting curves and the importance of holding a steadily decreasing Rate of Rise as your roast progresses. ![]()
