Rosin Data Sheet
From fresh flower to rosin, this guide outlines each step in rosin production.
1. Drying Process
Purpose: Remove moisture for curing.
Duration: 7-14 days.
Ideal Temperature: 18-22°C (64-72°F).
Ideal Humidity: 55-60% RH.
Completion Indicator: Stems snap; buds dry but not brittle.
Air Circulation: Gentle, avoid direct fans.
Common Issues: Overdrying loses terpenes; too much moisture risks mold.
2. Curing Process
Purpose: Enhance terpenes and quality.
Duration: 2-4 weeks (up to 8 for max retention).
Ideal Temperature & Humidity: 15-20°C (59-68°F), 58-62% RH.
Storage: Airtight glass jars; burp daily for two weeks.
Pressing Readiness: Aim for 62% RH.
Terpene Impact: Improves flavor and aroma.
3. Pre-Press Preparation
Purpose: Consistent density and yield.
Tool: Pre-press mold (optional).
Load per Press: 5-10 grams.
Optimal RH: 55-62%.
Micron Bags: 90-120 microns for clean rosin.
4. Pressing Parameters
Temperature Range: 70-120°C.
Low Temp (70-85°C): Best for terpene retention.
Medium Temp (85-105°C): Balance flavor and yield.
High Temp (105-120°C): Max yield, reduced terpenes.
Pressure Application: Gradual to prevent blowouts.
Yield Impact: Higher temps produce darker rosin with more yield.
5. Pressing Dry Sift Hashish
Material Type: Dry sift hash (kief).
Temperature: 70-85°C for terpene preservation.
Press Time: 60-120 seconds.
Pressure Application: Gradual to avoid blowouts.
Micron Bags: 25-37 microns for fine filtration.
6. Expected Yields
Top-Shelf Flower: 20-30%.
Mid-Quality Flower: 12-18%.
Low-Quality Flower: 8-12%.
Very Low Quality Flower: 3-8%.
Strain Dependence: Yields vary with trichome density.
7. Live Rosin Process
Material Type: Fresh frozen flower.
Extraction Method: Ice water hash; freeze dry for best quality.
Press Temperature: 70-85°C to preserve terpenes.
Optimal RH for Hash: 58-62% to prevent brittleness.
8. Storage of Rosin
Purpose: Maintain potency, flavor, and texture.
Safe Containers: Airtight glass jars (glass is chemically inert).
Avoid:
Silicone and Parchment: Terpenes degrade these materials.
Plastic: Degrades with terpene exposure.
Storage Conditions: Cool, dark place below 20°C.
Freezing Option: Store in glass; thaw slowly.
Quick Facts & In-Depth Insights
Live Rosin: Made from fresh frozen flower, retaining "live" flavor.
Terpenes & THC: High-THC strains often contain fewer terpenes.
Micron Bags: 90-120 microns for flower; 25-37 microns for hashish.
Heat & Terpenes: Above 70°C, terpene loss occurs; lower temps retain flavor. - After processing, the terpenes will naturally evaporate at 21°C and above during storage.
Yield vs. Quality: Lower temp = better quality, lower yield.
Storage Tip: Freeze long-term in glass; thaw slowly to preserve texture.
