CRC Members' Café- Understanding Drying & Curing in Cannabis

🌿 CRC Members’ Café – Understanding Drying & Curing in Cannabis (Post-Harvest Science Deep Dive) Original Publication: September 2022 Join the Cannabis Research Coalition (CRC) in this highly detailed exploration of post-harvest best practices—with a focus on drying, curing, water activity, and terpene behavior. This session offers growers, processors, and researchers a practical yet science-driven roadmap for achieving consistent quality, improved shelf life, and better control over aroma and potency. 🧪 What You'll Learn 💧 Drying vs. Curing – Key Differences Defining drying: physical water loss down to 0.6 water activity Defining curing: chemical and physical changes after drying Why moisture redistribution inside the bud matters 📏 Measuring Moisture & Water Activity Three methods to assess moisture content accurately How to measure water activity (Aw) and why 0.6 is the golden number How improper moisture levels influence Botrytis risk and microbial activity 💨 Vapor Pressure Deficit (VPD) Explained How temperature + humidity = drying speed Visualizing fast vs. slow drying curves using VPD Balancing speed, quality, and microbial safety during dry-down Why "60/60" (60°F, 60% RH) is a common—but not only—target 🌬️ Terpene Retention and Drying Conditions How high heat and airflow can damage terpene profiles Why fast drying can cause outer crisp, inner wet buds New insights into air velocity’s impact on aroma 🫙 Curing and the Purpose of “Burping” What really happens when buds sit in jars post-drying Evidence that moisture continues to redistribute and release How daily purging helps stabilize water activity and improve uniformity 🌸 The Fate of Terpenes During Storage Headspace vs tissue analysis of terpene concentrations Monoterpenes (like myrcene, limonene) = highly volatile Sesquiterpenes (like β-caryophyllene, humulene) = less volatile, more stable How this affects fragrance, smoke quality, and medicinal potential 🔥 Is Curing About Smoothness Too? Parallels with tobacco curing: sugars, acids, and pH changes Potential implications for smoking harshness and combustion behavior in cannabis Ongoing research into how curing may influence subjective quality experience 💡 Key Takeaways Drying is physics. Curing is chemistry. Understand both to optimize your product. Speed kills… aroma. But too-slow drying increases risk. VPD lets you strike the balance. Moisture meters, water activity probes, and headspace testing are tools every serious cultivator should explore. Uniformity in drying is just as important as average moisture—especially for large buds. Burping isn’t just ritual—it’s backed by data. 🧠 Presented by the CRC | Hosted by experts in cannabis horticulture and post-harvest science 📍 CRC Café – Monthly Meeting 📅 Next Topic: Flushing & Yield Impacts with Mike Alden #CannabisDrying #CannabisCuring #PostHarvestScience #CannabisResearch #Terpenes #WaterActivity #VPD #CannabisMoisture #BudBurping #CRCMeeting #CannabisProcessing
