Curing process: perfecting flavour and potency

Curing is the final and most critical step for premium cannabis quality:

**Curing science:**

*What happens during curing:*

- Chlorophyll degradation for a milder flavour

- Terpene development and preservation

- THC stabilisation and slight increase

- Moisture redistribution

- Optimise enzymatic processes

*Biochemical processes:*

- Starches convert to sugars

- Proteins degrade

- Cell walls become more permeable

- Aromatic compounds develop

- Resins mature

**Equipment for curing:**

*Glass containers:*

- Airtight glass jars (Mason Jars)

- Correct size (1 litre optimal)

- Wide opening for handling

- UV protection (brown jars)

- Several for different flavours

*Humidity Packs:*

- 58-62% RH Boveda packs

- Automatic humidity regulation

- Long term protection

- Various sizes available

- Partially reusable

*Monitoring:*

- Small hygrometers for glasses

- Digital precision

- Min/Max memory useful

- Calibration important

- Multiple for different batches

**Curing process:**

*Initial Fill:*

- Fill jars 75% full

- Do not overfill

- Mix different bud sizes

- Remove stems

- Loose but tightly packed

*First week (open daily):*

- 2x daily for 15-30 minutes

- Fresh air exchange

- Check humidity

- Mould inspection

- Turn buds carefully

*Second week (every 2 days):*

- Less frequent ventilation

- Humidity stabilises

- Chlorophyll degradation progressing

- Flavour development noticeable

- Patience important

*Week 3-4 (2x weekly):*

- Significant improvement in flavour

- Smoothness develops

- Terpenes mature

- Long-term storage possible

- Reach quality peak

**Moisture management:**

*Optimum RH values:*

- 58-62% for curing

- 55-58% for long-term storage

- Above 65%: Risk of mould

- Below 55%: Terpenes evaporate

- Aim for constant values

*Moisture correction:*

- Too dry: Add Humidity Pack

- Too humid: Leave open longer

- Avoid dramatic fluctuations

- Gradual adjustment

- Patience with corrections

**Problems and solutions:**

*Excessive humidity (>65%):*

- Open and ventilate immediately

- Remove buds from glass

- Further drying

- Mould control

- Start again if necessary

*Humidity too low (<55%):*

- Use humidity packs

- Open less often

- Smaller pieces of bud

- Orange/lemon peel for a short time

- Accept that terpenes are lost

*Mould detection:*

- Remove affected buds immediately

- Check surrounding areas

- Sterilise jar

- Re-evaluate remaining material

- Caution with further consumption

**Long-term storage:**

*Optimal conditions:*

- Temperature: 15-20°C

- Humidity: 55-58%

- Darkness (UV protection)

- Stable conditions

- Minimal handling

*Storage container:*

- Airtight jars

- Vacuum bags for long-term storage

- Metal containers (tinplate)

- Use Humidity Packs

- Labels with date

*Quality maintenance:*

- Annual quality checks

- Renew Humidity Packs

- Mould inspection

- Temperature fluctuations v
