How to Make a Cannabis Tincture with Grain Alcohol

In this guide, we'll walk you through how to make a cannabis tincture with grain alcohol, step by step. We'll also cover tips to make sure you're getting the potency you want — and how tools like the tCheck THC and CBD potency tester can help you measure your results with confidence.

🌿 Why Choose a Cannabis Tincture?

Fast-acting (when used sublingually): Drops under the tongue can take effect in as little as 15–30 minutes.

Discreet & portable: Small bottles make dosing easy on the go.

Long shelf life: Properly stored tinctures can last over a year.

Versatile use: Can be taken sublingually, added to drinks, or even infused into recipes.

If you want control, convenience, and effectiveness, tinctures are hard to beat.

🔬 How to Make Your Own Cannabis Tincture

Before diving into the step-by-step process, it helps to understand why grain alcohol is the gold standard solvent for cannabis tinctures.

🌿 Why Grain Alcohol Makes the Best Cannabis Tincture

Not all alcohols are created equal for cannabis extraction. Grain alcohol — typically Everclear at 190-proof — outperforms vodka, rum, and isopropyl alcohol for one key reason: it dissolves cannabinoids and terpenes without introducing unpleasant flavors or harmful residues.

The high ethanol percentage (95%+) ensures thorough extraction of THC, CBD, and minor cannabinoids from your decarboxylated cannabis. Lower-proof spirits leave water behind, which can cause cloudiness and reduce extraction efficiency. Food-grade grain alcohol is safe to consume and produces a clean, shelf-stable tincture that can last 1–2 years when stored properly.

⚠️ Safety First: Grain Alcohol Is Highly Flammable

Before you start, understand the risks. Grain alcohol is extremely flammable — never work near open flames, stoves, or any ignition source. Work in a well-ventilated area away from sparks. Use glass or stainless steel containers, not plastic. Keep the cap on the bottle when not actively pouring.

This is not meant to discourage you — millions of people make cannabis tinctures safely at home. Just treat grain alcohol with the same respect you’d give any flammable liquid in the kitchen.

🫙 Tincture Storage Best Practices

Proper storage is what gives tinctures their exceptional shelf life. Store your finished tincture in amber glass dropper bottles — the dark glass blocks UV light that degrades THC over time. Keep them in a cool, dark location: a pantry drawer, medicine cabinet, or refrigerator all work well.

Avoid plastic containers; THC can leach into certain plastics over time. Label each bottle with the date made, the strain used, and the potency (mg/mL) — which you’ll know exactly after testing with your tCheck tincture potency tester. A well-stored grain alcohol tincture can remain fully potent for 1–2 years.

What You'll Need

• • 1 ounce of cannabis flower (decarboxylated – more on that below)
  • 2–3 cups of high-proof grain alcohol (such as Everclear, at least 190 proof if legal in your area)
  • A glass mason jar with lid
  • Cheesecloth or a fine mesh strainer
  • A small funnel
  • Amber glass dropper bottles (for storage)
  • Optional: tCheck tincture potency tester to verify strength

Step 1: Decarboxylate Your Cannabis

Raw cannabis doesn't have much THC or CBD in a form your body can use. Instead, it contains THCA and CBDA, which need to be converted into their active forms through decarboxylation (heating).

How to decarb:

• • Preheat your oven to 240°F (115°C).
  • Break your cannabis into small chunks (not powder).
  • Spread evenly on a baking sheet lined with parchment paper.
  • Bake for 30–40 minutes, stirring halfway through. This step activates the cannabinoids, making your tincture effective.

Step 2: Combine Cannabis and Grain Alcohol

• • Place your decarboxylated cannabis into the mason jar.
  • Pour in enough grain alcohol to fully cover the cannabis, with at least 1 inch above the flower.
  • Seal the jar tightly and shake gently.

Pro tip: A higher alcohol-to-cannabis ratio generally leads to a smoother-tasting tincture.

Step 3: Cold Extraction (Green Dragon Method)

The most popular way to make a cannabis tincture is the Green Dragon method:

• • Store the sealed jar in the freezer for at least 2 weeks.
  • Shake it once a day to help the alcohol extract cannabinoids and terpenes.
  • After 2–4 weeks, strain the mixture through cheesecloth into a clean jar.
  • Use the funnel to transfer your finished tincture into amber dropper bottles.

For a faster option, some people shake vigorously for just 24–48 hours, but the longer you wait, the stronger the tincture.

Step 4: Test Your Tincture's Potency

Here's where things can get tricky: tinctures can vary widely in strength depending on your cannabis, decarboxylation, and alcohol ratio. Instead of guessing, you can use the tCheck THC and CBD potency tester to measure exactly how strong your tincture is.

With tCheck, you'll know the milligrams of THC or CBD per milliliter of your tincture. This means you can:

• • Adjust your recipe for future batches
  • Dose confidently without worrying about taking too much
  • Save money by making the perfect potency every time

Step 5: Dose & Store Properly

Typical dose: Start with 1–2 drops under the tongue and wait at least 45 minutes before increasing.

Storage: Keep tinctures in a cool, dark place. Amber bottles protect against light damage, extending shelf life.
