Guía de prensa de Rosin: Cómo hacer concentrados sin disolvente en casa

La colofonia es una de las formas más puras de concentrado de cannabis, elaborado sin disolventes, solo calor y presión. A diferencia de los extractos de BHO o CO2 que requieren equipo profesional y productos químicos potencialmente peligrosos, la resina se puede preparar de forma segura en casa con una prensa de colofonia. Esta guía cubre todo lo que necesitas saber sobre el prensado de colofonias, desde elegir equipos hasta perfeccionar tu técnica.

respuesta rápida

La coronilla es un concentrado de cannabis sin disolvente elaborado mediante la aplicación de calor y presión sobre las flores de cannabis, el hash o el kief. Una prensa de colofonia utiliza placas calentadas para exprimir el aceite rico en tricomas, produciendo un extracto puro rico en terpeno. Los ajustes de temperatura de 180-220 °F (82-104 °C) funcionan mejor para la flor, con 90-120 segundos de tiempo de prensa. Los rendimientos de colofonia de calidad oscilan entre 15 y 25% dependiendo del material de partida.

¿Qué es la resina?

La colofonia es un concentrado de cannabis sin disolvente creado a través de la extracción de calor y presión. A diferencia de BHO (aceite de hachís de butano) o extractos de CO2, la colofonia no requiere disolventes químicos, lo que lo convierte en uno de los concentrados más limpios disponibles.

Por qué la colofonia es especial

puro y limpio: Sin disolventes residuales, nunca. sale lo que entra.

espectro completo: Conserva terpenos y cannabinoides menores cuando se presiona a temperaturas adecuadas.

diy por diy: A diferencia de otros concentrados, la colofonia se puede hacer de forma segura en casa.

uso inmediato: No se requiere purga ni postprocesamiento: presione y díbate.

Rosin vs Otros concentrados

Tipos de colofonia

Resina de flores: Presionado directamente de los cogollos de cannabis. Más accesible para prensas caseras.

Hash rosin: Presionado de picadillo o tamizado seco. Resultados más limpios y de mayor calidad.

Live rosin: Presionado de hachís congelado recién congelada. Producto premium, terpenos máximos.

Rosin Pressing Basics

The Science

Rosin works by heating cannabis material until the trichomes (containing cannabinoids and terpenes) become liquid enough to flow out under pressure. The goal is to:

• Melt the trichome heads
• Squeeze the oil through plant material
• Collect on parchment paper

What Affects Quality

Starting material: Garbage in, garbage out. Quality flower or hash produces quality rosin.

Temperature: Higher temp = more yield but less flavor. Lower temp = less yield but more terpenes.

Pressure: Consistent, even pressure without blowing bags or crushing plant material.

Time: Too short leaves oil behind; too long degrades quality.

---

Temperature and Pressure Settings

Temperature Guidelines

Low and slow (160-190°F / 71-88°C):

• Maximum terpene preservation
• Lower yields (10-15%)
• Lighter color, budder consistency
• Best for: Premium hash rosin

Medium (190-220°F / 88-104°C):

• Balanced flavor and yield
• Moderate yields (15-22%)
• Good terpene retention
• Best for: Most flower pressing

Hot and fast (220-250°F / 104-121°C):

• Maximum yields (20-25%+)
• More degraded terpenes
• Darker color, more stable
• Best for: Older material, maximum extraction

Pressure Guidelines

Flower: 500-1500 PSI at the bag

Hash/Kief: 300-800 PSI (less is more)

Bubble hash: Very gentle pressure

Time Guidelines

Best Starting Material

Flower Requirements

What to look for:

• Fresh, properly cured (62% humidity)
• Visible trichomes
• Dense, resinous buds
• No mold or contamination

Ideal characteristics:

• Harvested at peak ripeness
• 2-4 weeks cured
• Stored properly
• High resin content strains

Best strains for rosin (high resin):

• Gorilla Glue
• Papaya
• Chem varieties
• Rosin-specific cultivars

Hash Requirements

Bubble hash:

• Full melt (5-6 star) produces best results
• 73-120 micron typically best
• Properly dried and cured
• Free of contamination

Dry sift:

• High quality only
• Minimal plant contamination
• Properly aged

Moisture Content Matters

Too dry: Poor flow, low yields, light color

Too wet: Sizzling, contaminated oil, dark color

Just right: ~55-62% RH, flows cleanly, good yields

Rehydrate dry material with a humidity pack for 24-48 hours before pressing.

Step-by-Step Pressing Guide

Equipment Needed

• Rosin press
• Parchment paper (unbleached, food-grade)
• Rosin bags (optional but recommended for flower)
• Collection tool
• Pre-press mold (optional)
• Timer
• Gloves

Pressing Flower Rosin

Step 1: Prepare Material

• Start with 3-7g properly cured flower
• Break into smaller nugs (don't grind)
• Load into rosin bag (90-120 micron for flower)
• Pre-press into flat puck if using mold

Step 2: Set Up Press

• Cut parchment to size (larger than plates)
• Fold parchment, place bag in center
• Set temperature (start at 200°F)
• Allow plates to stabilize

Step 3: Press

• Place parchment/bag between plates
• Apply light pressure initially (30-45 seconds warm-up)
• Gradually increase to full pressure
• Watch for oil flow to edges
• Total press time: 90-120 seconds

Step 4: Collect

• Remove parchment immediately
• Let cool slightly (30 seconds)
• Use collection tool to gather rosin
• Store on fresh parchment in cool location

Pressing Hash Rosin

Key differences:

• Use 25-37 micron bags
• Lower temperature (160-190°F)
• Much less pressure
• Shorter press time
• More valuable material—be careful!

Maximizing Yields

Pre-Press Tips

• Humidity is crucial: 55-62% RH for flower
• Pre-press molds: Create uniform pucks for even extraction
• Bag selection: Match micron size to material
• Temperature stabilization: Wait for consistent heat

During Pressing

• Gradual pressure: Don't smash—slowly increase
• Watch the flow: Stop when flow slows significantly
• Plate placement: Center material on plates
• Consistent batches: Same size/weight for predictability

Post-Press

• Collect quickly: Warm rosin collects easier
• Re-press material: "Second press" at higher temp recovers some oil
• Proper storage: Cool, dark, airtight

Expected Yields

Flower rosin: 15-25% yield is good

Hash rosin: 60-85% yield from quality hash

Kief rosin: 40-60% yield typical

Yields depend heavily on starting material quality

---

Pro Tips

1. Fresh, resinous material matters more than press quality

2. Lower temp = more terpenes, even if yield drops

3. Pre-press molds dramatically improve consistency

4. Bottle tech (directional folding) improves flow patterns

5. Let plates stabilize 5-10 minutes before pressing

6. Humidity packs can save overly dry material

7. Keep logs of temp/time/yield for each strain

8. Second press at +20°F recovers additional oil

9. Cold cure rosin in a sealed jar for improved texture

10. Quality bags are worth it—cheap bags blow out

FAQ

How much rosin can I make from an ounce of flower?

With quality material and good technique, expect 4-7 grams of flower rosin from an ounce (14-25% yield). Hash rosin yields much higher percentages from less material.

Do I need rosin bags?

For flower pressing, yes—bags filter out plant material. For hash pressing, bags are essential. You can press without bags but rosin will contain plant contamination.

What's the best temperature for rosin?

For most flower: 190-210°F (88-99°C) balances yield and quality. Hash should be pressed cooler at 160-190°F. Experiment to find your preference.

Why is my rosin dark?

Dark rosin can result from: high pressing temperature, old/degraded material, too much pressure, or moisture issues. Lower temps and fresher material produce lighter rosin.

Can I smoke rosin like regular wax?

Yes! Rosin is consumed like other concentrates—dabbed on a rig, used in a vaporizer, or added to flower. It's ready to use immediately after pressing.

Is a hair straightener press worth trying?

As a proof of concept, yes. For regular use, no. Hair straighteners lack pressure control and consistent temperatures. A proper press is a worthwhile investment for regular pressers.

How long does rosin last?

Properly stored (cool, dark, airtight), rosin lasts 6-12 months. It may change texture over time (budder up or become more stable) but remains usable.

Why isn't anything coming out?

Common causes: material too dry, temperature too low, not enough pressure, poor quality starting material, or bags too tight. Adjust variables one at a time.

Conclusion

Rosin pressing is one of the most rewarding ways to create cannabis concentrates at home. With no solvents and relatively simple equipment, you can produce clean, potent, terpene-rich concentrates that rival commercial products.

Success comes from quality starting material, proper temperature and pressure settings, and attention to detail. Start with good flower, dial in your technique, and keep records of what works. With practice, you'll be pressing dispensary-quality rosin in your own home.
