Cold curing at 16°C (60.8°F) is a carefully chosen process to balance several critical factors in preserving the quality and medicinal properties of cannabis. Here’s why this specific temperature is ideal:

1. Terpene Preservation

Volatility of Terpenes: Terpenes, which contribute to the flavor, aroma, and therapeutic effects of cannabis, are highly volatile. At 16°C, most terpenes are stable and less prone to evaporation compared to higher temperatures (e.g., 18°C), where some lighter terpenes like myrcene can begin to degrade.

At lower temperatures (e.g., 14°C), some terpenes can crystallize or condense, potentially leading to undesirable flavor or consistency changes.

2. Moisture Content Management

Controlled Drying: At 16°C, the environment encourages slow and even drying of residual moisture in the buds, preventing overdrying, which could make the cannabis brittle, or under-drying, which increases the risk of microbial contamination.

3. Microbial Stability

Mold and Bacteria: Temperatures above 16°C can slightly increase the risk of microbial activity, while lower temperatures may slow curing too much, leading to uneven results. At 16°C, the process is slow enough to prevent microbial growth without stalling enzymatic processes that enhance flavor and potency.

4. Chlorophyll Breakdown

Reduction of Harshness: The curing process involves breaking down chlorophyll and other plant compounds that can cause harsh flavors. At 16°C, this process occurs optimally without risking terpene degradation or cannabinoid conversion, which may occur at higher or lower temperatures.
