About this episode

This episode discusses the impact of preheating on the Gene Cafe roaster and its effects on coffee roasting consistency and development.

In this episode of the Roast It Yourself Podcast, Stephen from Coffee Bean Corral and Catherine of Current Crop Roasting Shop tackle a question many home roasters have wondered about: Should you preheat your roaster — specifically the Gene Cafe? Listener Ilona writes in after purchasing several origins and noticing that some roasters swear by preheating, while others skip it entirely. Stephen and Catherine break down: What preheating actually does inside a drum roaster How thermal mass affects roast progression When preheating can help (and when it may not matter much) The difference between intentional preheating and simply roasting back-to-back How your goals for the cup should influence your decision If you roast on a Gene Cafe — or any home drum roaster — this conversation will help you think more intentionally about your workflow, consistency, and roast development. Whether you're chasing brighter acidity, better momentum into first crack, or just more repeatable results, this episode gives you practical insight without overcomplicating things.
