Rosin Puck Tincture (QWET Method) — Complete Step-by-Step Guide

This is the most important part of a clean rosin puck tincture.

You must freeze BOTH:

• Decarbed cannabis material
• Ethanol alcohol

Freeze time: Minimum 24 hours

Why?

Cold temperatures dramatically reduce chlorophyll extraction and keep your tincture lighter in taste and color.

Step 3 — Choose the Right Alcohol

The ideal solvent is:

190 proof (95%) ethanol

You can use weaker alcohols, but here’s what happens:

Water content pulls unwanted compounds — so higher proof = cleaner tincture.

Step 4 — The QWET Wash

Take the frozen jar and frozen alcohol out of the freezer.

Pour just enough ethanol to fully cover the material.

Seal tightly and shake gently for a few seconds.

Then follow the timing cycle:

1. Freeze 5 minutes
2. Shake briefly
3. Freeze 5 minutes
4. Shake again
5. Freeze 5 minutes

Total wash time: ~15 minutes

Do NOT continuously shake — grinding damaged cell walls and aggressive agitation releases chlorophyll.

Step 5 — Filtration (Do NOT Rush This)

Set up:

• Cheesecloth
• Bottle or jar
• Funnel

Pour the mixture through the cheesecloth and let gravity do the work.

⚠️ Important:
Do NOT squeeze or press the material.

Because the pucks were ground finely, forcing filtration pushes plant particles and chlorophyll into the tincture, ruining flavor and color.

Patience here equals quality.

What Color Should It Be?

Your finished rosin puck tincture will likely appear green — that’s normal with reused material.

A darker green usually means:

• More plant compounds extracted
• Slightly harsher taste

Potency Expectations

Rosin pucks vary wildly, but typical ranges:

• Mild press leftovers: ~10 mg/ml
• Average: 20–50 mg/ml
• Strong batches: 75+ mg/ml

Light-based testers can struggle reading tinctures with heavy chlorophyll because the particles interfere with optical measurement.

In other words — if it won’t register, it may actually be very strong.

Tips for Cleaner Results

Use shorter washes
Longer = greener

Keep everything frozen
Temperature controls extraction selectivity

Don’t over-agitate
Shaking pulls plant waxes and pigments

Never press the cheesecloth
Biggest quality killer

Can You Use Regular Flower Instead?

Yes — the same process works perfectly with standard cannabis.

The only difference:
Flower usually produces a lighter, better-tasting tincture than rosin pucks.

How to Use the Finished Rosin Puck Tincture

Start low and slow.

Suggested beginner dose:
0.25 ml – 0.5 ml

Hold under tongue for 30–60 seconds before swallowing.

Onset time:
15–45 minutes (sublingual)
1–2 hours (swallowed)

Final Thoughts

Making a rosin puck tincture is one of the best ways to recycle pressing leftovers and recover valuable cannabinoids you already paid for. With proper freezing, short wash times, and gentle filtration, the QWET method produces a surprisingly potent and usable extract.

If you’re pressing regularly, you should never throw pucks away again — they’re basically edibles waiting to happen.
