What is Rosin?
The ultimate guide to premium solventless cannabis concentrates
Understanding Rosin
Rosin is a premium cannabis concentrate made using only heat and pressure—no solvents like butane or propane required. This solventless extraction method preserves the plant's natural cannabinoids and terpenes, resulting in a pure, flavorful, and potent product that cannabis connoisseurs highly prize.
At The Library dispensary in West Orange, we offer high-quality rosin products for discerning cannabis enthusiasts seeking the cleanest, most flavorful concentrates available.
How Rosin is Made
The Rosin Press Method
Rosin extraction uses a specialized press that applies controlled heat (180-220°F) and immense pressure (600-1500 PSI) to cannabis flower or hash. This process squeezes out the resinous trichomes containing cannabinoids and terpenes.
Preparation: Cannabis flower or hash is placed between parchment paper
Pressing: Heat and pressure are applied for 30-90 seconds
Collection: Golden, sticky rosin oozes onto the parchment paper
Curing: Optional curing enhances flavor and texture
No solvents = No residual chemicals. That's the rosin advantage.
Types of Rosin
Flower Rosin
Made directly from cannabis flower. More affordable and accessible. Golden color with robust flavor.
Hash Rosin
Made from bubble hash or dry sift. Higher quality and purity. Lighter color and more refined taste. Premium pricing.
Live Rosin
Made from fresh-frozen cannabis, preserving maximum terpenes. The highest quality and most flavorful rosin. Strong aroma and complex flavor profile. Read our live resin guide for comparison.
Live Hash Rosin (LHR)
The ultimate premium: fresh-frozen cannabis → bubble hash → pressed into rosin. Peak flavor, potency, and purity. Top-tier pricing reflects exceptional quality.
Rosin vs Other Concentrates
| Type | Extraction | Purity | Price |
|---|---|---|---|
| Rosin | Heat & Pressure | Very High | $$$ |
| BHO/Shatter | Butane Solvent | High (if purged) | $$ |
| CO2 Oil | CO2 Solvent | High | $$ |
| Distillate | Chemical Process | Very High THC | $ |
Rosin's solventless nature makes it the cleanest concentrate option, though typically at a premium price point.
How to Use Rosin
Dabbing (Most Common)
Use a dab rig with a heated nail or e-nail. Vaporizes rosin for immediate, potent effects. Requires equipment: dab rig, torch/e-nail, dabber tool.
Best temperature: 500-600°F for flavor preservation
Vaporizer Pens
Some concentrate-compatible vape pens work with rosin. Portable and discreet option. Check device compatibility first.
Look for ceramic chamber vaporizers
Adding to Flower
Place small amount inside a joint or on top of a bowl. Enhances potency of regular flower. Beginner-friendly method.
Use sparingly—rosin is very potent
Edibles (DIY)
Decarb rosin and infuse into oil or butter. Creates potent homemade edibles. Requires precise temperature control.
Consult guides for proper decarboxylation

Rosin Storage & Handling
Proper storage is crucial for maintaining rosin quality and potency.
- • Temperature: Store in cool, dark place. Refrigerate for long-term storage.
- • Container: Use air-tight, light-proof glass or silicone containers.
- • Light: Keep away from direct sunlight which degrades cannabinoids.
- • Handling: Use clean dabber tool. Don't touch rosin with fingers.
- • Shelf Life: 6-12 months when properly stored; weeks if left at room temperature.
Signs of Degraded Rosin:
Dark color, harsh taste, diminished aroma, or dry/crumbly texture indicate oxidation. Still safe but less enjoyable.
