We Don't Use CRC. Here's Why

March 27, 2026

THE PUREXTRACTS LETTER A note on craft, process, and why we refuse to cut corners.

At Purextracts, we believe the final product in your hand should tell the full story of the plant it came from. That's a simple idea. But executing it honestly, at every step of the process, is anything but simple.

Let's walk you through how we do it.

It Starts With the Right Flower

We source our hemp flower exclusively from indoor cultivators in the Bay Area — growers who treat their craft the way a winemaker treats their vineyard. Two of our trusted partners are State Flower and Pearl Pharma, operations known within the industry for dialing in genetics, environment, and phenotype expression with a level of precision that outdoor and greenhouse grows simply cannot replicate.

Indoor cultivation means:

Consistent light cycles that drive cannabinoid and terpene development
Controlled humidity and temperature eliminating mold, pests, and environmental stress
Phenotype stability across harvests — so the Grape Cream Cake you loved in January smokes the same in July

We don't source based on price. We source based on profile. If the flower doesn't express something distinct and worthy of extraction, we don't run it.

Light Hydrocarbon Gets a Bad Rap. Here's the Truth.

When most consumers hear "hydrocarbon extraction," they picture industrial solvent, harsh process, and a product stripped of everything that made the plant interesting. That reputation exists — but it's a reputation earned by people doing it wrong.

Here's what light hydrocarbon extraction actually does when executed correctly:

Butane and propane, used at precise temperatures and pressures, are selective solvents. They have a natural affinity for the compounds we want — cannabinoids, terpenes, flavonoids — and a low affinity for the compounds we don't want, like chlorophyll, plant waxes, and water-soluble material.

No other solvent system pulls the full terpene profile of a living flower the way light hydrocarbon does. CO₂ runs hot and fast and leaves you with a flat, monolithic extract. Ethanol is non-selective — it grabs everything including the material that muddies flavor and color. Hydrocarbon, done right at sub-zero temperatures, is essentially a cold snapshot of the plant's chemistry at its peak.

The result? When you open one of our vape carts, it should transport you directly back to the jar of flower it came from. Same nose. Same profile. Same identity.

That's the standard we hold ourselves to.

The Step Everyone Rushes — And Why We Never Will

After extraction comes refinement. This is where most operations quietly make a decision that compromises everything that came before it.

The industry shortcut is called CRC — Color Remediation Chromatography. It involves pushing extract through filtration media — bleaching clays, silica, activated carbon — to strip color and produce a product that looks clean and premium. Bright, clear, visually appealing.

The problem: CRC doesn't just pull color. It pulls terpenes. It pulls the very aromatic compounds that give your extract its identity — the reason you chose that strain, the reason it works the way it does for you. What you're left with is a visually attractive product that has been quietly emptied of its character.

CRC exists because it makes remediation fast, cheap, and cosmetically appealing. It papers over poor starting material and sloppy process. It is, at its core, a way to make a bad extract look like a good one.

We will never use CRC. Not on our live resin. Not on our vape carts. Not under any circumstances.

Our refinement process is proprietary — developed and refined over years of iteration — and it is built around one principle: preserve what the plant gave us. Color in a well-crafted extract is not a flaw. It's information. It tells you the terpenes are still there.

Why This All Matters in Your Cart

When you pull from a Purextracts vape cart, you're experiencing the output of a full chain of intentional decisions:
