Our classroom has been closed a year! And it's been hard to get it together with some online info. Thompson cranked out this little session though, geared toward the home roaster who can't get enough info about the changes in the coffee bean during first and second crack. Unfortunately the roaster is a bit noisy in the middle parts, but there is a lot of little nuggets of information in this presentation of nearly 35 minutes! #homecoffeeroasting #sweetmarias #firstcrack #secondcrack #roastinggreencoffee www.sweetmarias.com Instagram: / sweetmarias Facebook: / sweetmariascoffee Twitter: / sweetmarias Sweet Maria's Coffee Library: https://library.sweetmarias.com/
