Want to know how to make stronger cannabis tincture? Fordee’s method is a double infusion cannabis tincture — take your already-made Green Dragon tincture, add fresh decarbed cannabis (or hash), and run it through the Magical Butter Machine a second time. He went from 9.5 mg/mL to 14.4 mg/mL — a 51% cannabis tincture potency increase in one extra 4-hour session.
How to Make Stronger Cannabis Tincture: The Double Infusion Method
The concept behind a double infusion cannabis tincture is simple: alcohol can hold more cannabinoids than one infusion cycle typically extracts. By running a second infusion with fresh cannabis material — in this case, 11–12g of decarbed hash at ~40% THC — you push the alcohol closer to its saturation point, significantly boosting the final concentration.
3 Steps to Reinfuse Green Dragon Tincture
Here’s exactly how Fordee did the reinfuse green dragon tincture process to achieve the tincture mg per ml increase:
- Step 1: Add your existing tincture to the Magical Butter Machine. Pour in ~500ml of already-infused 190-proof (95%) alcohol tincture — the starting point was 9.5 mg/mL from the first infusion. You can see it’s that deep green color — the dragon is out.
- Step 2: Add fresh decarbed cannabis material. Fordee used 11–12g of decarbed hash (~40% THC). You can also use decarbed flower or concentrate — whatever you have. The key is it must be decarboxylated first. Set the machine to 160°F on the alcohol setting (4 hours).
- Step 3: Strain and test. After 4 hours, strain the tincture (a filter and syringe work well for TCheck testing). Use a potency tester — Fordee’s TCheck 2 read 14.4 mg/mL. That’s a 51% increase over the starting 9.5 mg/mL, without having to dilute the tincture down to stay below 15 mg/mL.
Safety Warning: Electric Heat Only
When working with high-proof alcohol, never use a gas burner — fire and alcohol equals an explosion risk. Use an electric stovetop or an infusion machine like the Magical Butter Machine that controls temperature safely. This is especially important when trying to how to make stronger cannabis tincture with 190-proof spirits, which are highly flammable.
Tincture mg Per mL Increase: Results and Notes
The tincture mg per ml increase from this double infusion was significant: 9.5 → 14.4 mg/mL, an improvement of ~4.9 mg/mL. Fordee expected around 5 mg/mL of gain based on the amount of hash added and its potency — which was spot-on. A few important notes:
- Absorption limit: Alcohol can only hold so many cannabinoids — it’s not possible to keep re-infusing forever. The alcohol will reach saturation at some point, and you’d need to dilute or accept diminishing returns.
- What cannabis to add: You can use flower, hash, or concentrate — whichever is available. Hash and concentrates are already more potent per gram, so you get more THC per gram added.
- Decarb is essential: Raw cannabis won’t contribute THC. Everything added in the second infusion must be decarboxylated first.
- Storage: Keep your tincture in an airtight bottle (wine bottle stoppers that remove air work well) and store in a cool, dark place to preserve potency.
Frequently Asked Questions
Can you double infuse any cannabis tincture?
Yes — the double infusion technique works for any alcohol-based cannabis tincture. The principle applies to Green Dragon (high-proof alcohol) as well as lower-proof tinctures, though high-proof alcohol (190 proof / 95%) is far more efficient at extracting cannabinoids. You can also apply a similar double-pass concept to oils and butters, though the temperature limits are different.
How do you know when to stop re-infusing?
The practical limit is the absorption capacity of your solvent. For alcohol, each milliliter can only hold a finite amount of dissolved cannabinoids — estimates vary, but you’ll know you’re approaching the limit when additional infusions produce diminishing results. Testing with a potency device like the TCheck 2 after each infusion is the most accurate way to track progress and determine when re-infusing stops being efficient.
What proof alcohol is best for tinctures?
190 proof (95% ABV) is the most effective for extraction — it pulls more cannabinoids per gram of cannabis than lower-proof options. 151 proof (75.5% ABV) or Everclear 151 is also widely used and easier to source in many regions. Avoid anything below 60% ABV (120 proof) as the water content interferes with extraction efficiency and can lead to a weaker, cloudier tincture.
